My dad works at a wastewater treatment plant and one of his coworkers fell in. He didn't drown but he did immediately have to be placed on large amounts of a broad spectrum of antibiotics because of all the microbes. He didn't develop any disease though so it all worked out
When I worked in a dirty water plant you would get a flu like infection at the beginning of working there, then after that colds and the flu would just bounce right off you.
@@larryleventhal1148 my dad rarely got sick before but yeah he says that he thinks he's got a stronger immune system after working there. I guess it makes sense if you consider being exposed to way more things outside of a person to person transition scenario
I worked at a Textron wastewater plant a couple of months ago and the grading fell through and I went into the clarifier... No antibiotics or anything else was needed even though I got a giant gash in my left forearm and neck. Needless to say I quit 9 days later.
I work at a sewage treatment plant and I have to say that I'd still be scared to fall into one. Not because of the buoyancy, neither because of the germs, but because of the crazy current from the inlets and zero visibility. If your eyes sink under the surface, there is almost no way to know which way to swim.
yeah there are storys of sewage treatment plant divers going into these tanks that havent been sectioned off propally and getting sucked into holes (with metal and rubber fully encapsulating dive suits) that are 10's of cm in diamiter
Exactly. A sudden change in environment as you fall in, a strong current you're trying to swim against, and a less-buoyant fluid than normal. The warning signs for these tanks is effectively the same as those at the beach warning of riptide currents.
The plant I work at has huge metal scrapers that go along the bottom(like a treadmill) Someone fell in a died before I started work there. No one knows what killed him though
Being a chemical engineer, I've visited several waste treatment facilities. I've warned my colleagues about not entering aeration tanks. The response was usually something like, "Gee, thanks, Chris. I was just about to jump into an ocean of s---, and you stopped me from doing that!"
I work at a wastewater treatment plant, the most dangerous thing when falling into any tanks is the oxygen displacement from various gases produced from the waste. We had someone die from falling into the sludge tank and even though it was only chest deep he died from asphyxiation.
There have been cases on boats’ anchor chain lockers of people dying from asphyxiation due to the lack of oxygen from the chains rusting. Pretty sure it happened on the USS Marblehead, but I know that isn’t the only example
non-bouyant water is also one of the theories regarding some of the happenings in the bermuda triangle. The theory is essentially that methane gas pockets build beneath the sludge and then release beneath ships, causing them to become less bouyant, capsizing them. I should add that this is something that doesn't have to be specific to the bermuda triangle, considering that it doesn't seem to be a statistical anomaly in the first place(in reference to the number of disappearances). It's just a theory that has been tied to the bermuda triangle for "reasons".
Actually nothing unusual happens in the Bermuda triangle. Numerous studies have shown that the rate of accidents and disappearances in that area is no different from any sea area of comparable size and traffic.
During my swift water rescue training, we had a "boil swim" where you go into the boil at the bottom of a low head or spillway. Mind you, we had rescuer PFD's on and wet suits. Hit that aerated water and went clunk on the bottom.. about 7-8' deep. I sat there for a second and got my bearings before rolling out from it. You WILL sink in aerated water and if you're not prepared, that's where they'll find you.
it relay boils down to intensity of bubbles, but yeah, in hight speed hight stress situations it's better to avoid any potential dangers because of a poor judgment due to brain being overloaded with adrenaline
@@Tommy1marg that's the hardest lesson to learn or teach, to mentally take a step back and analyze what's going on and to then take the proper steps to get out of the problem one is unexpectedly confronted with. I've been caught by rip currents, while merrily heading out to sea, evaluating what was happening and cut across the current to get out of it. I've also caught an offshore current, which was marked on nautical maps of the area that I just happened to blunder into (Coast Guard station was near the beach I was at), noticed I was quite distant from the shore and moving around 4 knots toward NYC from NJ. Seeing that and remembering the current marked on the map, I cut across the current and eventually waded back to the beach I was at. Fighting the current is the recipe for disaster, as water's a hell of a lot stronger than we are! Laughably, what brought my attention to the problem was, a shark swam between my legs, brushing against my inner thigh. As sand sharks tend to be in deeper water, when I turned toward shore, well, whoopsie that doesn't look good... The lifeguard looked quite alarmed, until he saw me cut the current and start wading back. First failure, losing situational awareness. Lesson learned. He who panics drowns.
@@spvillano "Laughably, what brought my attention to the problem was, a shark swam between my legs, brushing against my inner thigh." Hey thats one life I've heard of saved by a shark, we could cut that out of like the... 11 shark fatalities that happen per year!
As a wastewater engineer this warms my heart. Wastewater just doesn't get enough focus and recognition. I want to add that there are other factors of danger to be considered: Especially on smaller plants there isn't a lot of personnel - sometimes just one person (even though in theory it isn't allowed). So if you fall in, you are on your own. Also most aeration basins I have seen have quite the excess height at the brim so you have to get to a ladder to get out.
Props to you man. People like you are the reason human civilization still has drinkable water despite the fact major cities produce enough waste to entirely clog the rivers they sit on.
I’m a industrial electrician and my company specializes in building water treatment plants, we’ve been warned many times of the dangers involved especially with the “water full of air” as some of us call it. Glad to see this information get shared.
@@dujilli Not OP, but same profession here. It's great. I'm a union electrician and it really changed my life for the better. I would really recommend joining unions and the skilled trades if you can handle the hard work.
That's actually terrifying! The first instinctive reaction of anyone falling into one of those vats would be to swim to the edge. Based on the diagram shown at 10:16, that's exactly where they would be at greatest risk of being pulled under and drowning.
Not exactly since they would then get pushed into the center. If the force isn't enough, they can quite easily kick off the wall or just swim toward the center. I would imagine it's more of the panick that kills people, not the actual water having much of an affect
@@snakevenom4954 Part of the flow that goes back to the center is at the bottom of the tank. Not the place you want to find yourself in. Either way, aerated water would make staying on the surface more tiring, increasing the chance for drowning. Even if it was caused by panic and disorientation.
@@snakevenom4954 After that same flow pushed you down underwater. But yeah, that part that pushes you up is fine. Mind you, all we have is that cartoony diagram from the video. We have alot of presumptions about where the air nozzles are, shape of the tank and so on. Its hard to be sure.
“These signs are probably scarier than they need to be, but that’s fine when your ultimate concern is someone’s safety.” Well said! I’m an electrician. Every day I stick my hand in a 480V power box or “bucket,” I risk my life, which is why I avoid doing it as much as possible. I wish more people were willing to accept the essentially hyperbolically displayed danger on warning signs because, in the end, that *chance* at death is what those signs are working to prevent.
Yeah, I remember the first time I did some programming work at a waste water treatment plant and asked why there weren't any ladders attached to the side of the aeration basins and was quickly told it was because if I fell in there would be no swimming to the side. Definitely a fact that sticks in the mind.
@@JamesChessman well technically it was a continous aeration basin (the difference being that in an aeration basin it's filled then goes through its stages empties out and refills, and a continuous aeration basin has several section that water continuously runs through separated into the correct sections to go through the aerobic, anaerobic, and anoxic process) and yes no ladders were connected because there was thought to be no point. When maintenance was required the basin was drained and ladders put in place to work on the bubblers.
@@patrickfrost9405 Sadly, absolutely not. Even if your only trying to drain certain zones and not the entire thing there's just no way you're going to empty it in any kind of timely matter. I work at a relatively small plant but even then we still get millions of gallons per day in pretty deep ditches. On top of that you have to consider that you are likely seeing constant flow into your plant, since people don't just stop pooping on masse. To empty a ditch completely you would need to call in a contractor with vactor trucks to suck out the fluid and then go dump it somewhere that doesn't just flow back into your plant anyway as you turn all of your incoming pumps off and shut all valves. tl;dr If somebody falls in and they are able to successfully tread water and float without getting ripped under, you are far better off just throwing long ass ropes in with the whole rest of your crew there ready to haul ass and yank them out.
I worked in the wastewater industry for years and watched as a guy who was cleaning out an aeration tank stepped into a sump and fell in over his head. He was not a happy camper after he crawled out. And the entire crew was laughing at him uncontrollably. Lucky for him he closed his mouth and eyes and didn’t get seriously injured or ill.
I've experienced turbulent flows with lots of air bubbles and it's terrifying, no matter how much you're flapping your arms and legs, you're just going down.
Same things happen to ships. There's been a theory going about the Bermuda triangle and natural gas being released and that taking ships down in seconds
I used to work in the offshore drilling industry. Whenever we started a new well we'd have to have a guy spend their entire shift "bubble watching". Disturbing the seabed while drilling the first phase of the well has the potential to release large volumes of gasses, to the point where the drilling rig would no longer be able to remain buoyant.
It seems like methane bubbles would create a greater loss of buoyancy because that gas is less dense than air (there might be other gases involved but I think that methane is a lot of this). Also I believe bubbles of less dense gases would rise faster, accelerating the reduction in buoyancy. I don’t know the exact danger of this but unless you are sure it is safe I can see why they check. The
@@IncredibleMD I can't speak for any rig other than the one worked on, and no we did not. I honestly thought I was getting the piss ripped out of me the first time I was told to do it.
I remember seeing a documentary about how a ship vanished, and one theory was that an underwater eruption of some kind aerated the water making the ship lose buoyancy. They demonstrated it with a scale model and it was fascinating but it was a rogue wave that did it.
I seem to recall this was trying to explain vessel losses in the Bermuda Triangle. IIRC it was suggested that they were methane bubbles, which would also take out aircraft either by killing the engines or exploding.
I think I remember seeing the same documentary. Something about a release of methane gas from a vent below that would displace the water enough to alter the surface tension and cause a ship to get pulled under. At least that's what I remember.
WARNING! Do not go in for a swim! A collegue of mine, a chemist, fell into a water processing tank while getting samples due to ice on the walking bridge. We were able to get her up and out of the "water" within a few minutes and she spent the rest of the day in the sauna to get rid of as much bacteria as possible. Still she fell ill and was at risk of dying from fever and infection during almost two weeks after the incident. These tanks are dangerous and not for swiming... if you fall into them, you can die several weeks later from the infection.
Lmao a sauna was the worst choice. Giving germs a moist sweaty place that won't dry off is a bad idea. Moisture and warmth will almost always increase the rate of germ growth. Also a sauna would have to be too hot for a person to even use it, to even kill some germs. She should have immediately seen a doctor, they would have given her an antibiotic regimen.
@@garretth8224 Maybe not, it could induce an artificial fever which would help in the inside before the body realized that it was under attack. EDIT: I'm not a doctor.
2:13 I still remember the way my freshmen science teacher taught it to us: "Less dense things float on more dense things." It's simple and easy to remember
Another easy way to remember it: picture the surface of the water as a delicate cloth, and then imagine what would happen if you stretched this cloth tight in the air and placed a small heavy object on it, it'd go right through the cloth, but if you placed an object with larger surface area and less weight on it, the cloth wouldn't rip. Surface area also has a lot to do with it, that's how you can have ships with metal hulls floating. They have lots and lots of surface area to push against the water with. The same principle also works with parachutes. You won't float on air with a big enough parachute, however it does make your descent slower for the same reason.
It's why you can layer drinks too. Some alcoholic beverages and juices and shit are denser than others. As long as you break the momentum of its fall with a spoon, you can balance one on another.
I worked for years in the wastewater treatment industry. This was something we always had to explain to visitors when they toured our treatment plant. That, and yes, we had hundreds of poop jokes.
One WWTP the company I worked for, built from a green field, had your typical dog and pony show on completion. The aerators at this facility didn’t use spargers . It used a large pump to splash water against flat plate to aerate it. Well, the mayor fell in and you can probably guess the rest. That must have been nearly 40 years ago.
@@Ryarios sorry I can't guess the rest... Superbly interested for you to share what it is 🙂. Apologies as I've never worked in these treatment plants to fill in the blanks
Interesting idea, I wonder how often that really happens, or what the odds are of getting hit by such a thing. Seems like rogue waves are a more likely cause.
I actually learned about this in my oceanography class. My teacher said that around the Bermuda Triangle area there’s a large amount of these methane bubbles, so it’s a possible reason that so many vessels go down in the area
Hi, hello, ex diver here (Like diving boards with flips and sh*t). Anyway we actually put aerators in the bottom of the dive tank during practice for a few reasons! 1 it lets you see the surface of the water easier, and 2 if you mess up your flips and belly flop from 3 meters high the water is quite broken up (less surface tension and lots of air bubbles) it hurts a lot less. Pretty cool stuff! Aerated water definitely feels different but you can swim in it!
@@1TwistedPoet You're not wrong, but the difference between them is so small that one would have to go to extremes to actually see a visible difference... and at that point you're dead either way.
Part of it could be the large amount of CO2 released by the microbes caused those people to pass out from lack of oxygen and then drown. I remember touring the Jack Daniels distillery a couple of decades ago and they would not let you too close to the fermentation tanks because of this.
Weird side note: I once heard a theory that ships disappearing in the Bermuda Triangle could have been cause by underwater landslides, that released a large amount of gas. Said gas then aerated pockets of ocean enough for ships to sink. Whether that’s true is up for debate, but was interesting anyway.
Specifically its methane. large deposits of methane gas are trapped below the ocean floor in hydrothermal vents, and the theory is that large amounts of methane could be released at once could essentially create giant bubbles that simultaneously lower the buoyancy(Methane is less dense than air) and provide upward momentum from the bubble popping(and sometimes exploding) which cause ships to capsize. Also for aircraft, the theory is that if it happens to be flying directly above one of the massive methane bubbles popping, then then concentration in the air could be high enough to make the planes engine stall/explode.
I saw a BBC video that tested that in small scale and it looks viable... there's only one problem: As LEMMiNO's excellent video details, the Bermuda Triangle needs no explanation. Ships and planes don't disappear at an unusual rate, given the amount of traffic and the weather conditions, and people like to sloppily assign blame to it for things that didn't happen anywhere near it. (I'm reminded of the line that gets said again and again on Skeptoid in various forms. "Before looking for an explanation, confirm that what needs an explanation actually exists." The Bermuda Triangle is a classic case of writers spicing mundane things up to increase readership.)
@@ssokolow I think I remember that video. I've also seen one on how a training flight of the US Air Force I think it was got turned around and ended up perishing at sea after their compasses started spinning on their own. Turns out, they were merely blown off course by strong winds, and then got disoriented because they got confused which part of the map they were supposed to be looking at. They would have made it back to the mainland... except the flight's leader made the (incorrect) call to turn around against the advice of ATC, and ended up dooming the entire flight.
I remember hearing about non-buoyant water when I was a kid and it sounded terrifying, like quicksand. Luckily, much like quicksand, it's not something you're just gonna accidentally happen across in your everyday life.
Technically, you can't fully submerge in quicksand either - humans are buoyant in it as well. You can go to a little bit above beer belly (+/- a bit depending on sand and temperature). The hollywood trope of submerged head with overreaching arm is impossible. Just breathe, lay flat on your front (if you know what you do) or back (if there is help around) and you will be fine.
I remember hearing that The Strid, considered as one of the most dangerous streams of water despite how unassuming it looks, is actually that dangerous because of how aerated and bubbly its water is from the way the stream flows in it, meaning that if you were to fall in that water, you would only sink.
Is also unbelievably deep despite the narrow channel. That aeration is compounded by anything that sinks gets caught in the many unseen rock overhangs deep beneath the surface.
Streams or rivers flow the aerated bubbles at random. Not just going up from the bottom like a tank does. So a river wouldn't always be counter acting buoyancy like the center of a tank would. That's what makes aerated water so dangerous in nature.
I've been cliff jumping near waterfalls before and the highly aerated white water at the foot of the falls definitely makes it a lot harder to swim, without the controlled vertical flow of bubbles like in the tanks I think you lose some of that upwards force
That is because the bottom of waterfalls is essentially acting as a drowning machine. Which is pretty much what the tanks are creating in effect - with the water going up in the centre and then going down at the edges. so creating circulation in the tanks.
Pretty sure that has nothing to do with aeration rather moreso the fact that the downward flow of the fall hitting the water creates a current that pulls you down.
„I dont fight Stupidity, as it's not a Crime. I fight willfull Ignorance, cause that pushes us back." -Professor Dave, famous Sciencedenial-Debunker and Scamartist-Catcher.
@@nspring06 even where it's burbling back up and pushing downstream it's still a noticable difference, usually just have to wait till it pushes you into calmer water
that's a different thing. what youre talking about is a natural drowning machine. Kyle did a video on that and even mentions natural waterfalls. you should check it. very interesting video also.
Same effect can occur when you aerate other materials. Like sand for example. The decreased density of the sand creates a situation where there is so much air that the density is decreased enough that it behaves more like a fluid than a solid. It's really neat
Hospitals have specialty beds with a mattress made of aerated sand. The surface moves as the sand circulates. So the person isn't laying in one static position, but instead this gently undulating surface. It's good for folks with impaired circulation and pressure ulcers (bedsores).
This reminded me of the fascinating Bolton Strid in England. It's a charming, peaceful looking creek that's 6 foot wide at most and has been killing people for centuries, as it absolutely looks like a simple stream of water you can jump across it or have a dip in. I recall people saying due to the small falls that the water there is very aerated, which is part of what contributes to making it very hard to escape the water. In addition to that however there is hidden underwater caves to either side under water, very maze like structures of rock that people are sucked down into when they fall in.
I don't believe the aeration is the big issue with it. It looks like a calm creek but it's moving incredibly fast right below the surface because it gets way wider, and has the underwater caves as you explain. Its essentially the king of all undercut River hazards, aka the most dangerous thing in a river.
@@ssjgeon I agree. Those underwater caves create turbulence below the surface that your typical whitewater doesn't. Combine with much faster velocity because what was once a wide channel is now narrow and imagine that every direction you swim in is like trying to swim against riptide. There is no direction where you can swim parallel to the waters movement the entire height of the channel and therefore no way to reliably float. Although I've studied the hydrodynamics of rivers I am nowhere near expert level so take what I said with a grain of salt.
I am replaying MGS2 right now and Vamp's fight is honestly the first thing I think of when I hear non-buoyant water. It's pretty terrifying to think about.
I did that fight on the hardest setting and I found the best road to victory was when he jumps into the water, just pump stingers into him. But yes... I too immediately though of Vamp when I saw this video... Phil LaMarr really brought that character to life... As he does with all his roles.
Could be worse. It could have magic sharks attacking you like Kojima originally planned. Edit: So I was actually wrong about this. There were sharks cut from the game but they weren't magic. I got it mixed up with the character that would have summoned a dragon to fight you in the water with his tattoo. Still freaking crazy.
Ever worked around a grain silo? There's a reason it's a 3 person minimum job. That's by law in a lot of places. We have a 4 man minimum at work with big signs giving warning. Even bigger ones for the large machinery.
Might there also be a possibility of CO2 buildup at the bottom that could lead to suffocation if unattended? That's another cause of lethal accidents within deep, enclosed areas.
Huh, I always knew about the *"Dead Sea" in Jordan* where you can EASILY *float* in it thanks to its extreme *high salinity,* but I never knew about the OPPOSITE of that kind of water until this video! Thanks Kyle! :]
some quarry lakes are also known to release air bubbles from the earth under the water, causing streams of bubbles to rise up, and if you jump in the quarry in the wrong spot you'll sink 200 feet like a rock
You might also consider the risk of “splash drowning” - aspiration of water without being fully submerged - as a substantial risk when being unexpectedly dropped into an aerated pool with less buoyancy and a more fluid boundary between liquid and air. It’s a major risk for inexperienced people in whitewater exploits such as tubing.
This is actually hilarious to me now. Someone who worked at one of these places came to my science class and tried showing us what would happen if you fall into one of these claiming you would just sink and drown. But when he did his experiment to back his claim he used a fan pushing air into the bottom of a tank full of water and dropped something into the tank expecting it to sink but it floated just as it did with the fan off. He got super embarrassed and red faced and couldn't give a reason to why it wasn't working. Poor guy was just accidentally ahead of his time.
The metal gear battle over the non buoyant water was awesome whether it was non buoyant water, heavy water or just learning the different grades of water it's all pretty interesting.
@@scunnerdarkly4929 what's fascinating to me is that you can actually drink heavy water, and it's fine, more or less. It's probably not a good idea to drink it every day. But many scientists have tried it. Apparently it tastes very sweet compared to normal water. And all it is is just water but with a different isotope of hydrogen. Deuterium. It's got dueterium in it, the same thing that powers starships in star trek. And you can drink it and it's nice. And it's mainly used in very old nuclear power plants, and nuclear weapon production facilities. Apparently that's why Germany's nuclear program in WWII never got off the ground, because they needed heavy water for their design, and only could source it from one factory in Norway. And the Norwegians deliberately sabotaged all the equipment so that Hitler was screwed. They all got shot, of course. Brave, brave men. They kinda saved the world a bit. Although Germany's nuclear program probably would have failed regardless because they killed or exiled all their top Jewish scientists, who had all gone to America to work on the manhattan project instead. I always wonder what would have happened if the bombs were dropped in Germany as originally intended. Like, Godzilla wouldn't exist. We'd have a German equivalent probably, called Gottzillanschneibenleifenstagreich or something. Anime wouldn't exist either, cos anime only exists because of the American occupation of Japan after World War II. So anime would be a German creation. Anyway I digress. Heavy water sounds so cool as a name. I don't wanna try it myself, mind you. Not that I'd ever be able to get a hold of any lol. But yeah.
Actually, you would have about 10% more buoyancy in heavy water. The idea being that the water itself being heavier, means you don't displace as much. And, by the way...D2O is a poison. Many substances have an LD50, (yes, even "regular" water), however, if you drink 30% of your body mass of heavy water, you just hit the LD50 of heavy water.
@@duffman18 Dilithium is actually a real thing, literally two covalently bonded Lithium atoms, just like Dihydrogen, except Dihydrogen has two Hydrogen atoms. However, the Star Trek Dilithium crystal is 2(5)6 dilithium 2(:)l diallosilicate 1:9:1 heptoferranide (Star Trek Next Geration Technical Manual). No deuterium in it.
I visited a wastewater treatment plant in 2011 and the guys there explained basically the same thing you said about the bubble columns forming a circulating flow (Which is good for the bugs) and that that's where the danger lies, I remember him saying "We tell everyone to swim straight to the middle and stay there until help arrives," so at least not everyone is wrong about this.
Legal reason for the signs just like hot warning on coffee without it anyone can sue including people trespassing that have no clearance to be there just like if someone jumps in your backyard when you got warning dog signs can use it as proof they knew you had a dog and entered without permission so they cannot sue you.
@@Jreb1865 I assume if the heat is stuck on your skin for long enough it would cause 3rd degree burns.

As a Wastewater Treatment Operator for over 10 years, thank you for bringing Wastewater treatment to the forefront and being a topic of awareness for the public. l
This is actually quite an interesting video, when I worked offshore, we are taught that if we have an underwater gas blowout, DON'T jump into the water because you will sink. Also, on another point, there are theories that when huge tracts of frozen methane on the bottom of the ocean start to bubble, the density of the water above drops, and causes it to boil/bubble faster causing large areas of ocean to turn over. This was a theory of what causes ships in the Bermuda Triangle to disappear without a trace, that they lost buoyancy and sank.
Statistically you're *NO more likely* to sink in the Bermuda Triangle, than any other part of the Ocean. Its just since its a part of major shipping routes, it gets more attention. Plus all of the click bait articles & videos & conspiracies have made it far bigger of a problem than it actually is.
That theory is absolutely terrifying. Just imagine being on a ship and the water around you starts to bubble intensely then you feel the ship begin to tilt. Fuck that's nightmare fuel.
@@erikcarrillo7378 Even more terrifying, is some would assume (I mean without the knowledge not ever seeing/hearing about this type of event) that the ship somehow created hole in the hull, and that's why it's sinking so quick. That panic, just to see that also every lifeboat is sinking because of the same event happening underneath them. 😱
Just fyi statistically there isn’t an unusual number of lost vessels in the Bermuda Triangle compared to similar shipping lanes. There just aren’t any other islands between Bermuda and the Virgin Islands.
As someone who work with human waste every day, I’d just like to say that, even though you might not drown in the flow of “non-bouyant-poop-water”, the contamination will. Just dont take a swim in it. That is all.
I don't think I'd work near those vats without a harness and recovery rope, and I just assume they're over 12' deep. I do know you absolutely will sink in giant stills filled with booze.
Around ten years ago, I fell up to my neck in what I can only imagine were waste water sludge dumping pits (as it is right next to the water treatment facility). A very thick, gelatinous black sludge that I always referred to as the "nuclear waste dumps". The top layer had frozen over in the winter so I was shoveling it off to skate on it, and right when I was in the middle of it the ice broke. Thankfully I was able to climb out of it somehow despite my heavy winter clothes, and made the trek back to my family's house through the below-freezing temperature. I need to email the facility and find out what that stuff was.
That's nasty and crazy glad you made it out okay, but sad you were dumb enough to try and ice skate over wastewater back then. Hopefully, you'll do better.
Non-buoyant water actually existed in mythology far back too. I remember a Chinese legend where Houyi (the guy who got exiled from heaven for doing his job because apparently the Jade Emperor, like most emperors, was really fucking bad at reasoning) had to cross a perpetually burning mountain full of fire and lava, as well as a *river with water that had no buoyancy* before scaling tall, treacherous cliffs with edges sharp as blades, which, at its peak, lived the god who brewed the elixir of immortality.
Your last statement is so true. When lives are on the line, the only correct direction to fudge the warning is in the direction of increased danger. If something has the potential to kill someone, a warning sign that makes that possibility sound more present just isn't something I'd waste my time or energy trying to correct (unless the exaggeration was so crassly incorrect as to be useless).
@@complainer406 wrong context. I'm not talking about waring people out with too many warnings. I'm talking about what decision a person makes when they don't know the true danger of something, and they're forced with potentially overstating, or understating, the danger. And the decision is, in my opinion, simple. When you don't know what the true danger of something is, you err on the side of caution. Caution means you choose to overstate the warning, rather than understate it.
Quick clarification: the tanks you show at the beginning when you say "these tanks" are actually Secondary Clarifiers, where the aerated water goes to settle. The water in those tanks is no longer aerated and not "non-buoyant", only Aeration tanks that use diffusion bubblers on the bottom of the tanks to aerate the mixed liquor create the non-buoyant water.
Yup, that's a *MAJOR PROBLEM* with today's people's political beliefs, anti-science people, anti-vaccination propaganda, flat earthers(seems to have died out thankfully), Q canon believers, believing Transgender is real & not actually gender dismorphia, believing Trump is an honest man/"greatest president ever", believing Biden is 100% mentally sharp (he's freaking 75+ with dozens of years dealing with stupid politicians & their even dumber voters) and I can *go on & on, & on with many more examples* of the problem with people extremely uneducated, especially on whatever topic is at hand, using *UA-cam videos, Facebook or other social media MEMES, unverified, non-credible, or other ridiculous methods* to try & achieve their ideologies. Has a lot to do with "Crabtree's Bludgeon" & "Ocean's Duct Tape" senarios, with a lack of "Alder's Razor" (look them up, if you don't understand what I was saying by mentioning those).😉 🤷 Common sense is *NOT* so common, in fact, the common person is actually pretty dumb, & when you get a collective of dumb people in a herd mentality, its absolutely near zero possibility to change their mind, even *WITH* indisputable facts/evidence. 🙄 -Sigh 😒

When I was in primary school, we visited the local sewage treatment centre and were told about this. So, I was taught this as a young child and have never forgotten since. It's not hard a difficult concept to grasp.
I work in marine salvage and we were towing a junk barge that had "broke loose" because the company didn't want to dispose of it. Anyways stuff hit the fan and I was on the barge running pumps and compressors and because the seam split it went down fast. luckily I had a good life preserver because on instincts I ran to the bow where we'd been filling with compressed air. By the time I realized I'd done effed up it was too late. But I tried jumping in and getting away and I swam about 5ft before the water really started pushing air out😮 and I sank like a rock....life vest and all. it was no joke even though I laugh about it now because it felt like being inside a washing machine on spin cycle. I'd get close to the surface and then back down until luckily the barge turned sideways. I didn't know it at the time and I got in position and kicked off the deck far enough out of the devil's cauldron to pop to the surface where I blacked out and slept through most of my ambulance ride. But at least I was awake for the helicopter ride to Cooper😂 who were absolutely amazing❤

"These signs are a little scarier than they need to be." I mean, the one just says "risk of drowning." I'm pretty sure the scary level of the sign is an exact match to the danger level of the tanks.
I went on a 5th grade field to a water treatment facility and when we went to look at one of the aeration tanks (idk if it was one or not) the person giving us the tour said that if you fell in you would drown because of the amount of bubble in the water. (I could be wrong as my memory is fuzzy)
Bruh, I am going to solve your mystery quite simply: When you drop a toothbrush in a toilet you've pretty much written off that toothbrush forever. I am pretty sure falling into a giant vat of poop water has the same effect on your desire to keep living. "Whelp, here I am in a sea of crap...guess I'll sink to the bottom and hope I do better in the next life"
The irony is that studies show our bathrooms are often 'cleaner' than our kitchens, in a microbial sense. Toilet water isn't the risk people assume: it's usually drinking standard; the bowl is cleaned & disinfected more often than plenty of other areas in our homes & flushed on a regular basis.
In actual fact, in most North American Bathrooms, the toothbrush is dirtier than the toilet. Your kitchen sink also, very likely, has a higher bacterial load than your toilet.
The moment Kyle started this presentation, I immediately thought about the MythBusters segment with Adam Savage being the test subject. I was so pleased when Kyle referenced those experiments. And while it was not mentioned here, Savage partially experienced the smaller tank what Kyle described at the 10:30 mark. He was pushed to the wall of the vinyl drum but the flow was not strong enough to to push down. In the swimming pool, the rig was far enough from the edge that Adam was not pushed that far.
I've always wondered what would happen if someone fell into a vat of vegetable oil or mineral oil. Since as we all know from elementary school science experiments oil is much less dense than water, and the humabn body is mostly water and thus has an average density similar to water, would a vat of processed kitchen oil be much more worthy of a warning sign like this?
kitchen oil is about 8% less dense. You wouldn't sink like a stone or anything but alot of people would be close to neutral bouyancy. Instead of just floating on your back or a very light treading you would really have to keep swimming moderately to keep your mouth in the air. So you'd be more likely to drown but if you were a reasonable swimmer and close enough to a way out you would likely be fine assuming you didn't panic.
@@denmark5354 You would swim just as well as normal. Although it's thicker, you get more force back when you kick/push the syrup. Mythbusters tried it out and found you swim just as well, no difference
I'd be more concerned about the medical risks of full body exposure to biohazardous waste. Why don't they just put a big net or screen/mesh/grate over the tank? It would allow it to breathe, but not allow a person to fall in.
@@oldman8996 Some wastewater treatment plants have a mesh/grate over the tanks. It's a safety feature. You can't put a price tag on a human life. If you're afraid of hard work (maintenance work) you should stay away from hard work and build your career at McDonald's.
2:39 Technically, the water bottle floats because the fluid it displaces has the SAME mass as the entire water bottle, not more mass. Balanced forces result in zero acceleration in the vertical dimension.
Around 10% of an iceberg protrudes above the water... Because when ice freezes, it gets about 10% bigger. When an iceberg melts, all the water fits in the hole it made. The melting of floating ice dies not affect water level, in any way.
@@1TwistedPoet What about the melting of ice that isn't already in the water? Ice on land? Don't you think the increase of volume through land-ice melting into the ocean would increase the water levels of the ocean?
@@quincycarra9107 Measure the size and thickness of the Ice Sheet you are concerned with. Take the total area, in square kilometers. Take the total area of the world's oceans. Divide one by the other, to get the number of ice sheets, of that size, that it would take to cover the oceans. Slice your ice pack horizontally into that many slices, and measure the thickness. Adjust downward by 10% to account for the volume differences in water and ice, and THAT'S how much deeper the oceans would be... Now, you also need to adjust downwards, slightly, to account for the fact that as the water gets deeper, it takes up, sometimes, significantly more area. Like, if the ocean rises 1 metre... Anything at an altitude of 1 metre or less above sea-level will now be underwater, increasing the surface area as it rises. And remember, it will take decades for it all to melt, if it does. It's not the crisis you've been lead to believe. We need to stop shitting where we live, and be better Stewards of the environment... but only because it is causing disease and cancers in US. We are making the planet uninhabitable for US! We are NOT "destroying the planet". We couldn't destroy the planet if you put Darryl Gates in charge of the effort. (You can look him up. I can't go doing ALL the work.) The wild poster child for Climate Change is the polar bear. Commies love using Bears for some reason. WWF is the Panda Climate Change, the Polar Bear... They use that photo of the emaciated bear, that looks like it's starving to death, with its ribs sticking out. THAT bear WAS starving to death. ...but because it had intestinal cancer. Polar bears as a SPECIES are doing fine, their population has exploded, and they are doing just fine. But when Award Winning Zoologist, Susan Crockford dared to SAY that in public, she was silenced, deplatformed, lost all her grants and her association to her University was terminated. She had only been studying the bears for 25 years, but CLEARLY she was lying to people about the bears. After all, we've ALL seen the photo. (Queue emotional response and sad music. Do we still have any crying Indians available?) Think critically and you can tell the difference between real research and facts, and when you are being fed a line of crap, with people waving "Science" in your face, too quickly for you to see it, and refusing to engage, publish or even acknowledge the existence of those that disagree. You'll recognize it by Narrative. When you look for the information in a wide variety of main stream sources, not only will the presented facts be the same... that much is common to good research... But the actual words used in the report will be IDENTICAL. The SAME words, in the same order. They are not investigating and reporting fact, they are copying over a script of an authorized Narrative. Remember, Boys and Girls, you only need a Narrative when you are telling a STORY. When you speak the truth, FACTS speak for themselves. That's what you have with Climate Change and the Green movement. They want YOU on board to "Protect the Environment". But the Watermelon movement (Green on the Outside, but RED in the Centre), is after ONE THING. The abolition of Private Property. Klaus Schwab of the WEF is quoted... "You will own nothing, and you will be happy." But Socialism HAS no happy ending. If the Sahara were run on Socialism, there would be a shortage of sand.
There's a component of creating signage and iconography that must take into account the understanding of the layperson. The message must be clear and adequately convey the danger while assuming that the person reading the warning sign has little or no background knowledge. Like the "high voltage" signage. You can split hairs about the actual danger of amperage vs voltage, but for the lay person "high voltage" is adequate. The issues discussed here about the aeration tanks are similar in my opinion. Sure, the real danger may be different than what the warning sign implies, but it really doesn't matter at the end of the day as long as the sign adequately impressed upon a lay person the relative danger.
There's fine line at which you stop caring about saving idiots from themselves... "You will drown" is more than enough to anyone with a functioning brain. They don't have to know how it works, they were warned that they WILL drown. Which is why I have an issue with "high voltage" and similar, you could easily send the same message by telling them that your hands will grip to the wire until your last breath.
there is a bit of a difference between a tank being filled with drinking water, and being filled with sewage. sewage or brown water is less dense than plain water, this is due the solids and dissolved particulates suspended in the water. with the bubble heading up, you also get water from the top circulating down, almost like a rip tide affect.
Thank you for this, loved it. The belief that sinking ships 'suck you down' comes from the loss of buoyancy caused by a ship full of air escaping underneath you - not so much aeration as big-ass bubbles - but even then, a guy who went down with the titanic and was on the outside of the stern railing when it went under says he didn't even get wet hair.

Anyone else first learn about Non-buoyant water from Metal Gear Solid 2? I was only 10 when I played it and I remember being so freaked out as Vamp (the boss) is explaining it's properties and how you just instantly died when you fell in.
This video stirred up memories from 18 years ago (May 2004) when the concrete dome that covered one of the digesters at the Spokane City Waste Water Treatment Plant collapsed dropping three men into the sludge severely injuring two and killing my father's best friend and coworker Mike Cmos Jr. The reason 3 men were on the dome was to clean it off so the houses above the treatment plant wouldn't complain about the plant looking dirty.
This was awesome. After watching, I thought, "hey there's a treatment plant I always pass. I remember seeing fire, and it smells. I wonder if it's anaerobic treatment?" So I went to my city's page and found the water pollution control, and was probably the first person to see that page in a long time. Sure enough, it's anaerobic treatment! With 3 treatment steps, after solid removals.
If you're seeing fire, then it's probably them using burning to get rid of their excess solids. The plant I work at uses a belt press feed system instead to run the waste sludge through a series of rollers to squeeze water out and then the final (mostly dry) product is dropped out on a big pad after being mixed with lime. It's then hauled away in trucks to be used in agriculture. The area around our ditch actually smells quite nice, b/c while the bugs eat the carbon in the solids they release nitrogen gas as their "waste product", which is slightly sweet smelling and just goes up and dissipates in the air.
I appreciate how you used diagrams of both trickling filter systems and activated sludge. I work in this industry and nobody seems to find it interesting at all. They just complain about the smell
12:01 most biogas (the methane gas mixture that is released from the anaerobic digesters) isn’t “refined on site”, as it’s way too “dirty” of a gas. Most WWTP, simply run the gas through extremely minuscule refinement (put through condensers, etc), then it is run through biogas engines to produce electricity. That biogas is still ~40%-60% methane (the remaining is CO2 and other gasses); making the gas unusable (far too dirty) for actual natural gas engines and producers.
I remember reading a study showing that the improvement in energy generation from converting biogas to methane was so slight that it made it not worthwhile to spend the energy cleaning it. Better just to use it as is.
Quite an informative video. I like to think of this as aerated sand or Liquid Sand. Where, in sand, you blow air from beneath and it turns the solid sand into liquid-like and you start to drown. Hence, can be compared to this.
Imagine if there was a place on Earth where this had the same effect but with gravity and it would be possible for an unknowing victim to jump up and be shocked to find himself falling up to the sky.
Nice idea! It would affect the air, too, which I imagine would make some violent weather! H. G. Wells sort of imagined this in "The First Men in the Moon"--there's this imaginary substance called Cavorite that stops gravity, which the protagonists use to lift their spaceship. The first time they make a sheet of it, it causes this atmospheric fountain that sucks the Cavorite up the chimney. They speculate that if that hadn't happened it could have peeled the atmosphere off the Earth like an orange. Eventually they're more careful and they make these sort of Venetian blinds out of it, which are mounted above and below their ship. When they want to go into space, they just close the blinds below the ship, cancel out the Earth's gravity and get pulled all the way to the Moon. Jules Verne didn't like the story, he said "come on, Wells just made up an antigravity substance, that's cheating. I did all the math for my giant Moon cannon."
The high school I attended has a water treatment facility directly behind the track/football field with the tanks of shit being the closest structures to the school. The smell atrocious, and the staff would refer to it as our homefield advantage. After going on a trip to the plant and being above these pools of crap, we realized that it smells much worse on ground level than actually being right above it.
Incredible city planning right there lmao. Then again, my city has the waste treatment plant on an island in the middle of the city. It would be prime real estate for an incredible house, business, or park, but nope. That's where we send the poop. You smell it every day driving over the bridge.
That is because the gasses produced are heavier than the atmosphere which means that it it falls to ground level just like water does in an overflowing tub of water.
Theres also this thing where during a ship sinking, the massive columns of air bubbles can form an oxygen elevator shaft that you can fall down through. Of course not talking about the bubbles in micro scale, but the big rolling bubbles that can be over 1-2 feet in diameter.
“…Massive columns of air bubbles can form an oxygen elevator shaft that you can fall down,” bro nice imagination but there’s no way that’s real, it’s a cartoon imagination
I thought it was the undertow current from large voids in the ship being filled with water that causes the suction and sometimes unfortunately drowns people. The imagery of a column of bubbles lining up in such a way for a human to actually fall down through is interesting to think about. I guess it could happen, But they tell you to swim away from ships because of the potential undertow, I believe.
@@benwestphal4076 yes there's hydraulic forces that will suck you down too, but a large volume of air from escaping air pockets out of the ships - depending on the size of the bubbles literally make you fall through the water.
@@utley actually this was tested by Myth busters and it's FALSE. A sinking ship will not pull you down with it if you're on top of it. There's no "sinking bubbles" that'll cause you to be pulled under water when a ship is sinking.
The second I saw the thumbnail I thinked about Vamp's boss fight! Thanks for mentioning it, I was wondering if it was true since 12 years. Heck, I even remember my first encounter with him and being like "I love how this game justify everything". Other than that, very interesting video ! You are very clear with your explanations!
Right? Normally when you fall into water in games and die it's for no real reason, so I really appreciated the attention to that. Didn't matter if it was true or not just the effort to explain was enough for me, but it's so cool that it's legit!
When I was in elementary school, we took a field trip to the water treatment plant. We got to tour the walkways of the tanks and what always stuck with me was being told that if you fell in the tank, you will get pulled down and drown because it's not buoyant. You can't swim in it without drowning. Still terrifies me.
As a Technical Support Engineer for IXOM Watercare (aka Medora Corporation) I’m going to show this good little informative video around the company. Our service crews work in these ponds and where we do require the aeration to be turned off while we service equipment, I think the guys could benefit from this excellent explanation to what is going on in those cells.
Sumps filters in aquariums run in the same principle. It is why we cycle aquariums before sticking in fish to get the beneficial bacteria in the filtration.
Interestingly, without it being a biohazard, the Mythbusters tested this some time ago with a large column of water they could float in but also inject large quantities of air in. They added air to froth up the water and down they sank. Turning the air back off again allowed them to float again.
I live in a town with a few different abandoned asbestos mines. The water at the bottom of the open pits are a beautiful cyan/blue, but the amount of minerals in the water make it so swimming in it is impossible. First responders have special dive training in the event that somebody decides to try
@@rakino4418 could be completely wrong but it could be the water is less dense causing a person to sink and be unable to rise in such water like how it’s hard to sink in the Dead Sea cause it has to much salt in it making it denser than most body’s of water
I’m a waste water operator. We did this test with clean water in the tank. One type of diffuser we used would push you up. The other types we used caused a current that would pull you under and slam you into the piping and tank bottom . Nice to see videos evolving water and wastewater treatment system.
Reminds me of when Mark Rober made a pool of sand that, when activated, would send air through the sand allowing you to move free in it as if it were a liquid.
I'm only 2min in, but surprised he didn't mention Minecraft. Water above magma blocks is aerated and will drag you down (and can sink boats). Oddly, I didn't make the connection til I was now years old ;)
While definitely not a topic of everyday conversation, I found this post very interesting and informative. Your presentation was very professional without being dry and drawn out. Double Kudos!
crazy to think that in elementary school, like 3rd grad, we went to one of these on a field trip. 3 teachers in charge of 80+ 9 year olds, around these waters with no safety nets, or anything... wild times hahaha
''and so they can eat your poop'' reminds me of my little brother when i try to explain something serious and then everything just gets ruined by that interruption assigning my explanation to his joke
Wastewater treatment is such an under-appreciated topic. I work in a lab that tests wastewater samples and part of what I do is measure the amount of biodegradable organic matter (i.e. poo) in pre-treatment and post-treatment samples. Spoiler alert, the aeration tanks are highly contaminated waters (and stink to high heaven - I warn my colleagues whenever I'm about to open a bottle of aeration tank sample!)
Toilet-to-tap leftist nonsense is probably going to ruin the rest of your career, the absolute insistence that process water become potable and served to people is so obviously political when I've got farmers on my system clamoring for more water, any water. But no, no, we have to drink the poopie water. They're actually doing that so that you get nowhere with everyone since if it became apparent that water is not oil and doesn't actually disappear into entropy a leftist somewhere might lose a job or some grant money. It's actually just political fraud perpetrated using every 4th grader's favorite thing, that's their use for you, that will be your 5 minutes on TV.
8:25 his appearance checks out, that totally looks like the kind of guy who would jump into a potentially deadly sewage for the sake of self experimentation. What a badass
As a lifeguard, they are very dangerous, if you cannot float there is very little you can do to swim let alone get saved. It should only be used in a swimming capacity for diving where a damping is needed.
My dad works at a wastewater treatment plant and one of his coworkers fell in. He didn't drown but he did immediately have to be placed on large amounts of a broad spectrum of antibiotics because of all the microbes. He didn't develop any disease though so it all worked out
When I worked in a dirty water plant you would get a flu like infection at the beginning of working there, then after that colds and the flu would just bounce right off you.
@@larryleventhal1148 my dad rarely got sick before but yeah he says that he thinks he's got a stronger immune system after working there. I guess it makes sense if you consider being exposed to way more things outside of a person to person transition scenario
Yeah. Even if the risk of drowning isn't any higher, you still generally want to avoid falling into wastewater.
heard of a guy in the same situation
Every orifice of his body had to be sterilized
I worked at a Textron wastewater plant a couple of months ago and the grading fell through and I went into the clarifier... No antibiotics or anything else was needed even though I got a giant gash in my left forearm and neck. Needless to say I quit 9 days later.
I work at a sewage treatment plant and I have to say that I'd still be scared to fall into one. Not because of the buoyancy, neither because of the germs, but because of the crazy current from the inlets and zero visibility. If your eyes sink under the surface, there is almost no way to know which way to swim.
Talk about a shitty day
Well then it’s your lucky day, because you can’t swim anyway. Lol
yeah there are storys of sewage treatment plant divers going into these tanks that havent been sectioned off propally and getting sucked into holes (with metal and rubber fully encapsulating dive suits) that are 10's of cm in diamiter
Exactly. A sudden change in environment as you fall in, a strong current you're trying to swim against, and a less-buoyant fluid than normal. The warning signs for these tanks is effectively the same as those at the beach warning of riptide currents.
The plant I work at has huge metal scrapers that go along the bottom(like a treadmill)
Someone fell in a died before I started work there. No one knows what killed him though
Being a chemical engineer, I've visited several waste treatment facilities. I've warned my colleagues about not entering aeration tanks. The response was usually something like, "Gee, thanks, Chris. I was just about to jump into an ocean of s---, and you stopped me from doing that!"
Gee, thanks, Chris. I was just about to enter an aeration tank, and you stopped me from doing that!
But, there's always some numpty that needs that warning!!
Well someone would probably take a swim in it . Curiosity and the cat and all that .
Challenge accepted
Intelligence and common sense aren't the same thing :P
I work at a wastewater treatment plant, the most dangerous thing when falling into any tanks is the oxygen displacement from various gases produced from the waste. We had someone die from falling into the sludge tank and even though it was only chest deep he died from asphyxiation.
I imagine H2S is a big risk?
Thats messed up
There have been cases on boats’ anchor chain lockers of people dying from asphyxiation due to the lack of oxygen from the chains rusting. Pretty sure it happened on the USS Marblehead, but I know that isn’t the only example
Killed by the stench
lot of respect to u guys. someone has to do it. backbone of our society
non-bouyant water is also one of the theories regarding some of the happenings in the bermuda triangle.
The theory is essentially that methane gas pockets build beneath the sludge and then release beneath ships, causing them to become less bouyant, capsizing them.
I should add that this is something that doesn't have to be specific to the bermuda triangle, considering that it doesn't seem to be a statistical anomaly in the first place(in reference to the number of disappearances). It's just a theory that has been tied to the bermuda triangle for "reasons".
Gandalf the legend himself
That’s honestly crazy to consider.
Actually nothing unusual happens in the Bermuda triangle. Numerous studies have shown that the rate of accidents and disappearances in that area is no different from any sea area of comparable size and traffic.
Gandalf what the hell
Came to say this, remember watching a really good documentary about it.
During my swift water rescue training, we had a "boil swim" where you go into the boil at the bottom of a low head or spillway. Mind you, we had rescuer PFD's on and wet suits. Hit that aerated water and went clunk on the bottom.. about 7-8' deep. I sat there for a second and got my bearings before rolling out from it. You WILL sink in aerated water and if you're not prepared, that's where they'll find you.
so basically, don't swim to the SOURCE of the aeration.
it relay boils down to intensity of bubbles, but yeah, in hight speed hight stress situations it's better to avoid any potential dangers because of a poor judgment due to brain being overloaded with adrenaline
@@Tommy1marg that's the hardest lesson to learn or teach, to mentally take a step back and analyze what's going on and to then take the proper steps to get out of the problem one is unexpectedly confronted with.
I've been caught by rip currents, while merrily heading out to sea, evaluating what was happening and cut across the current to get out of it. I've also caught an offshore current, which was marked on nautical maps of the area that I just happened to blunder into (Coast Guard station was near the beach I was at), noticed I was quite distant from the shore and moving around 4 knots toward NYC from NJ. Seeing that and remembering the current marked on the map, I cut across the current and eventually waded back to the beach I was at.
Fighting the current is the recipe for disaster, as water's a hell of a lot stronger than we are!
Laughably, what brought my attention to the problem was, a shark swam between my legs, brushing against my inner thigh. As sand sharks tend to be in deeper water, when I turned toward shore, well, whoopsie that doesn't look good... The lifeguard looked quite alarmed, until he saw me cut the current and start wading back.
First failure, losing situational awareness. Lesson learned.

As a wastewater engineer this warms my heart. Wastewater just doesn't get enough focus and recognition.
I want to add that there are other factors of danger to be considered: Especially on smaller plants there isn't a lot of personnel - sometimes just one person (even though in theory it isn't allowed). So if you fall in, you are on your own. Also most aeration basins I have seen have quite the excess height at the brim so you have to get to a ladder to get out.
Props to you man. People like you are the reason human civilization still has drinkable water despite the fact major cities produce enough waste to entirely clog the rivers they sit on.

The first instinctive reaction of anyone falling into one of those vats would be to swim to the edge.
Based on the diagram shown at 10:16, that's exactly where they would be at greatest risk of being pulled under and drowning.
Not exactly since they would then get pushed into the center. If the force isn't enough, they can quite easily kick off the wall or just swim toward the center. I would imagine it's more of the panick that kills people, not the actual water having much of an affect
@@snakevenom4954 Probably also them not knowing that they should seek out the center of the tank.
@@snakevenom4954 Part of the flow that goes back to the center is at the bottom of the tank. Not the place you want to find yourself in. Either way, aerated water would make staying on the surface more tiring, increasing the chance for drowning. Even if it was caused by panic and disorientation.
@@greenanubis That's fine tho. Since the flow that goes to the center would push you into the center. And hence, push you up

I wish more people were willing to accept the essentially hyperbolically displayed danger on warning signs because, in the end, that *chance* at death is what those signs are working to prevent.
Electricity and radiation are scary because they are invisible and can kill you instantly.
Like su*cide cords??
Those signs do the opposite. An abundance of false warnings means that actually dangerous situations can't be recognized.
Yeah, I remember the first time I did some programming work at a waste water treatment plant and asked why there weren't any ladders attached to the side of the aeration basins and was quickly told it was because if I fell in there would be no swimming to the side. Definitely a fact that sticks in the mind.
Dude there’s no way that’s true, who is running the treatment plant, Skeletor or some other evil villain? No way!!
@@JamesChessman it definitely is true and he’s got a point
@@JamesChessman well technically it was a continous aeration basin (the difference being that in an aeration basin it's filled then goes through its stages empties out and refills, and a continuous aeration basin has several section that water continuously runs through separated into the correct sections to go through the aerobic, anaerobic, and anoxic process) and yes no ladders were connected because there was thought to be no point. When maintenance was required the basin was drained and ladders put in place to work on the bubblers.
@@LifeWithMatthew Oh, since it can drain, it can easily be rigged to drain if it detects the weight of a person dropping in.
@@patrickfrost9405 Sadly, absolutely not. Even if your only trying to drain certain zones and not the entire thing there's just no way you're going to empty it in any kind of timely matter. I work at a relatively small plant but even then we still get millions of gallons per day in pretty deep ditches. On top of that you have to consider that you are likely seeing constant flow into your plant, since people don't just stop pooping on masse. To empty a ditch completely you would need to call in a contractor with vactor trucks to suck out the fluid and then go dump it somewhere that doesn't just flow back into your plant anyway as you turn all of your incoming pumps off and shut all valves.
tl;dr
If somebody falls in and they are able to successfully tread water and float without getting ripped under, you are far better off just throwing long ass ropes in with the whole rest of your crew there ready to haul ass and yank them out.
I think the major sticking point for me with falling in one of these would be fear of the microbes (bugs), not the aeration of the water.
Drowning seems to be a more pressing problem, but yeah that water would be nasty.
Last thought as drowning: "Yuck"
As a germaphobe, I'd honestly rather drown quickly than deal with the psychological aftermath of having been in that water.
@@kilgirlietrout I do find germaphobia somewhat ironic, since your body is full of microbial life that is quite literally essential for you to live.
I worked in the wastewater industry for years and watched as a guy who was cleaning out an aeration tank stepped into a sump and fell in over his head. He was not a happy camper after he crawled out. And the entire crew was laughing at him uncontrollably. Lucky for him he closed his mouth and eyes and didn’t get seriously injured or ill.
I've experienced turbulent flows with lots of air bubbles and it's terrifying, no matter how much you're flapping your arms and legs, you're just going down.
That is truely horrifying
Same things happen to ships. There's been a theory going about the Bermuda triangle and natural gas being released and that taking ships down in seconds

This doesnt help my fear of bodies of water....
AHH....So you're a ghost?
I used to work in the offshore drilling industry. Whenever we started a new well we'd have to have a guy spend their entire shift "bubble watching". Disturbing the seabed while drilling the first phase of the well has the potential to release large volumes of gasses, to the point where the drilling rig would no longer be able to remain buoyant.
It seems like methane bubbles would create a greater loss of buoyancy because that gas is less dense than air (there might be other gases involved but I think that methane is a lot of this). Also I believe bubbles of less dense gases would rise faster, accelerating the reduction in buoyancy. I don’t know the exact danger of this but unless you are sure it is safe I can see why they check. The

I remember seeing a documentary about how a ship vanished, and one theory was that an underwater eruption of some kind aerated the water making the ship lose buoyancy. They demonstrated it with a scale model and it was fascinating but it was a rogue wave that did it.
I seem to recall this was trying to explain vessel losses in the Bermuda Triangle. IIRC it was suggested that they were methane bubbles, which would also take out aircraft either by killing the engines or exploding.
@@walthodgson5780 it's clearly a djinn kingdom, that's why people there disappear even while they're still eating but the ships are fine /s
I think I remember seeing the same documentary. Something about a release of methane gas from a vent below that would displace the water enough to alter the surface tension and cause a ship to get pulled under.
At least that's what I remember.

WARNING! Do not go in for a swim!
A collegue of mine, a chemist, fell into a water processing tank while getting samples due to ice on the walking bridge. We were able to get her up and out of the "water" within a few minutes and she spent the rest of the day in the sauna to get rid of as much bacteria as possible. Still she fell ill and was at risk of dying from fever and infection during almost two weeks after the incident. These tanks are dangerous and not for swiming... if you fall into them, you can die several weeks later from the infection.
Lmao a sauna was the worst choice. Giving germs a moist sweaty place that won't dry off is a bad idea. Moisture and warmth will almost always increase the rate of germ growth. Also a sauna would have to be too hot for a person to even use it, to even kill some germs. She should have immediately seen a doctor, they would have given her an antibiotic regimen.

2:13 I still remember the way my freshmen science teacher taught it to us: "Less dense things float on more dense things." It's simple and easy to remember
Another easy way to remember it: picture the surface of the water as a delicate cloth, and then imagine what would happen if you stretched this cloth tight in the air and placed a small heavy object on it, it'd go right through the cloth, but if you placed an object with larger surface area and less weight on it, the cloth wouldn't rip. Surface area also has a lot to do with it, that's how you can have ships with metal hulls floating. They have lots and lots of surface area to push against the water with. The same principle also works with parachutes. You won't float on air with a big enough parachute, however it does make your descent slower for the same reason.
so then we'll all float in mercury easy, right? Right? :D
@@Dhalin wtf
It's why you can layer drinks too. Some alcoholic beverages and juices and shit are denser than others. As long as you break the momentum of its fall with a spoon, you can balance one on another.

I worked for years in the wastewater treatment industry. This was something we always had to explain to visitors when they toured our treatment plant. That, and yes, we had hundreds of poop jokes.
One WWTP the company I worked for, built from a green field, had your typical dog and pony show on completion. The aerators at this facility didn’t use spargers . It used a large pump to splash water against flat plate to aerate it. Well, the mayor fell in and you can probably guess the rest. That must have been nearly 40 years ago.

Methane bubbles from the sea floor could, in theory, sink ships and may explain the odd disappearances of some vessels
Interesting idea, I wonder how often that really happens, or what the odds are of getting hit by such a thing. Seems like rogue waves are a more likely cause.
Interesting, not very common, but plausible, you get a sticker :)
I actually learned about this in my oceanography class. My teacher said that around the Bermuda Triangle area there’s a large amount of these methane bubbles, so it’s a possible reason that so many vessels go down in the area
@@anastasiaolson3791 No it isnt, that has been debunked ages ago. Just search for bermuda methane debunked
No they cant, this has been debunked by scientists ages ago...
Hi, hello, ex diver here (Like diving boards with flips and sh*t). Anyway we actually put aerators in the bottom of the dive tank during practice for a few reasons! 1 it lets you see the surface of the water easier, and 2 if you mess up your flips and belly flop from 3 meters high the water is quite broken up (less surface tension and lots of air bubbles) it hurts a lot less. Pretty cool stuff! Aerated water definitely feels different but you can swim in it!
Water is softer than concrete... but only a LITTLE softer.
Especially from 3 or 5 metres.
Would depend on the volume of air in the water. I'm betting you guys don't crank out the bubbles like a waste treatment center.
@@1TwistedPoet You're not wrong, but the difference between them is so small that one would have to go to extremes to actually see a visible difference... and at that point you're dead either way.
I bellyfloped on water and it hurts
I choose to believe "flips and shit" was a lonely island reference.
Part of it could be the large amount of CO2 released by the microbes caused those people to pass out from lack of oxygen and then drown. I remember touring the Jack Daniels distillery a couple of decades ago and they would not let you too close to the fermentation tanks because of this.
Weird side note: I once heard a theory that ships disappearing in the Bermuda Triangle could have been cause by underwater landslides, that released a large amount of gas. Said gas then aerated pockets of ocean enough for ships to sink. Whether that’s true is up for debate, but was interesting anyway.
Hmmm 🤔 Interesting!
Could you give us a link? This sounds incredibly interesting
Specifically its methane. large deposits of methane gas are trapped below the ocean floor in hydrothermal vents, and the theory is that large amounts of methane could be released at once could essentially create giant bubbles that simultaneously lower the buoyancy(Methane is less dense than air) and provide upward momentum from the bubble popping(and sometimes exploding) which cause ships to capsize.
Also for aircraft, the theory is that if it happens to be flying directly above one of the massive methane bubbles popping, then then concentration in the air could be high enough to make the planes engine stall/explode.
I saw a BBC video that tested that in small scale and it looks viable... there's only one problem: As LEMMiNO's excellent video details, the Bermuda Triangle needs no explanation. Ships and planes don't disappear at an unusual rate, given the amount of traffic and the weather conditions, and people like to sloppily assign blame to it for things that didn't happen anywhere near it.
(I'm reminded of the line that gets said again and again on Skeptoid in various forms. "Before looking for an explanation, confirm that what needs an explanation actually exists." The Bermuda Triangle is a classic case of writers spicing mundane things up to increase readership.)
@@ssokolow I think I remember that video. I've also seen one on how a training flight of the US Air Force I think it was got turned around and ended up perishing at sea after their compasses started spinning on their own. Turns out, they were merely blown off course by strong winds, and then got disoriented because they got confused which part of the map they were supposed to be looking at. They would have made it back to the mainland... except the flight's leader made the (incorrect) call to turn around against the advice of ATC, and ended up dooming the entire flight.
I remember hearing about non-buoyant water when I was a kid and it sounded terrifying, like quicksand. Luckily, much like quicksand, it's not something you're just gonna accidentally happen across in your everyday life.
Technically, you can't fully submerge in quicksand either - humans are buoyant in it as well. You can go to a little bit above beer belly (+/- a bit depending on sand and temperature). The hollywood trope of submerged head with overreaching arm is impossible. Just breathe, lay flat on your front (if you know what you do) or back (if there is help around) and you will be fine.
when i head about non-buoyant water at first i thought its some bullshit kojima has invented, was suprised when i learned that its real thing
Hill should do an episode about quicksand if he hasn't already. Interesting non-Newtonian characteristics.
@@arekkrol9758 hate to break it to you but metal gear is actually a documentary
@@BigFx when the tide comes in u are screwed
I remember hearing that The Strid, considered as one of the most dangerous streams of water despite how unassuming it looks, is actually that dangerous because of how aerated and bubbly its water is from the way the stream flows in it, meaning that if you were to fall in that water, you would only sink.
I have watched so many Strid videos since I found out about it. Nightmare stuff for sure!
Is also unbelievably deep despite the narrow channel. That aeration is compounded by anything that sinks gets caught in the many unseen rock overhangs deep beneath the surface.
@@SlanderFails exactly this, the river essentially turns sideways and is so deep that they dont really know how deep
The bubbliness comes from the violent motion.
Streams or rivers flow the aerated bubbles at random. Not just going up from the bottom like a tank does. So a river wouldn't always be counter acting buoyancy like the center of a tank would. That's what makes aerated water so dangerous in nature.
Drowning in human waste must be the worst way to expire.
the best way 😋🤤
Depends on your kinks.
I've been cliff jumping near waterfalls before and the highly aerated white water at the foot of the falls definitely makes it a lot harder to swim, without the controlled vertical flow of bubbles like in the tanks I think you lose some of that upwards force
That is because the bottom of waterfalls is essentially acting as a drowning machine. Which is pretty much what the tanks are creating in effect - with the water going up in the centre and then going down at the edges. so creating circulation in the tanks.
Pretty sure that has nothing to do with aeration rather moreso the fact that the downward flow of the fall hitting the water creates a current that pulls you down.

@@nspring06 even where it's burbling back up and pushing downstream it's still a noticable difference, usually just have to wait till it pushes you into calmer water
that's a different thing. what youre talking about is a natural drowning machine. Kyle did a video on that and even mentions natural waterfalls. you should check it. very interesting video also.
Same effect can occur when you aerate other materials. Like sand for example. The decreased density of the sand creates a situation where there is so much air that the density is decreased enough that it behaves more like a fluid than a solid. It's really neat
They used this as a feature of how the Shai-Halud “swim” the sands of Arrakis in Dune
I love the video Mark Rober did on that >w
This is why people have "drowned" in corn and grain silos
Hospitals have specialty beds with a mattress made of aerated sand. The surface moves as the sand circulates. So the person isn't laying in one static position, but instead this gently undulating surface. It's good for folks with impaired circulation and pressure ulcers (bedsores).
In other words...quicksand.
This reminded me of the fascinating Bolton Strid in England. It's a charming, peaceful looking creek that's 6 foot wide at most and has been killing people for centuries, as it absolutely looks like a simple stream of water you can jump across it or have a dip in. I recall people saying due to the small falls that the water there is very aerated, which is part of what contributes to making it very hard to escape the water. In addition to that however there is hidden underwater caves to either side under water, very maze like structures of rock that people are sucked down into when they fall in.
falling in is 100% fatal
i think not even one soul got out once they were in
Only people known to successfully swim it as far as I know are scuba divers in full gear.
I don't believe the aeration is the big issue with it. It looks like a calm creek but it's moving incredibly fast right below the surface because it gets way wider, and has the underwater caves as you explain.
Its essentially the king of all undercut River hazards, aka the most dangerous thing in a river.
Always been fascinated with that. Wonder if there is some way to map it out?
@@ssjgeon I agree. Those underwater caves create turbulence below the surface that your typical whitewater doesn't. Combine with much faster velocity because what was once a wide channel is now narrow and imagine that every direction you swim in is like trying to swim against riptide. There is no direction where you can swim parallel to the waters movement the entire height of the channel and therefore no way to reliably float. Although I've studied the hydrodynamics of rivers I am nowhere near expert level so take what I said with a grain of salt.
I am working in Water and Waste Water Treatment Operations. You did us proud Thanks!👍👍
I am replaying MGS2 right now and Vamp's fight is honestly the first thing I think of when I hear non-buoyant water. It's pretty terrifying to think about.
Agreed
I did that fight on the hardest setting and I found the best road to victory was when he jumps into the water, just pump stingers into him. But yes... I too immediately though of Vamp when I saw this video... Phil LaMarr really brought that character to life... As he does with all his roles.
And then Vamp goes swimming in it anyway
Could be worse. It could have magic sharks attacking you like Kojima originally planned.
Edit: So I was actually wrong about this. There were sharks cut from the game but they weren't magic. I got it mixed up with the character that would have summoned a dragon to fight you in the water with his tattoo. Still freaking crazy.

Grain voids are terrifying and deadly, good on your workplace
Is it for fear of people falling into the grain?
@@pixpusha Yeah, think quicksand, but real and worse.
Might there also be a possibility of CO2 buildup at the bottom that could lead to suffocation if unattended?
That's another cause of lethal accidents within deep, enclosed areas.
E Smith grain silos can aerate the grain from below to dry it and prevent mold growth. if it blows hard enough, the grain pretty much liquifies.
Huh, I always knew about the *"Dead Sea" in Jordan* where you can EASILY *float* in it thanks to its extreme *high salinity,* but I never knew about the OPPOSITE of that kind of water until this video! Thanks Kyle! :]
some quarry lakes are also known to release air bubbles from the earth under the water, causing streams of bubbles to rise up, and if you jump in the quarry in the wrong spot you'll sink 200 feet like a rock

7:12 He’s kinda looks like Shia LeBeouf when he does the “just do it”
You might also consider the risk of “splash drowning” - aspiration of water without being fully submerged - as a substantial risk when being unexpectedly dropped into an aerated pool with less buoyancy and a more fluid boundary between liquid and air. It’s a major risk for inexperienced people in whitewater exploits such as tubing.
This is actually hilarious to me now. Someone who worked at one of these places came to my science class and tried showing us what would happen if you fall into one of these claiming you would just sink and drown. But when he did his experiment to back his claim he used a fan pushing air into the bottom of a tank full of water and dropped something into the tank expecting it to sink but it floated just as it did with the fan off. He got super embarrassed and red faced and couldn't give a reason to why it wasn't working. Poor guy was just accidentally ahead of his time.

Once in a while those little experiments actually serve a purpose.

@@scunnerdarkly4929 what's fascinating to me is that you can actually drink heavy water, and it's fine, more or less. It's probably not a good idea to drink it every day. But many scientists have tried it. Apparently it tastes very sweet compared to normal water. And all it is is just water but with a different isotope of hydrogen. Deuterium. It's got dueterium in it, the same thing that powers starships in star trek. And you can drink it and it's nice. And it's mainly used in very old nuclear power plants, and nuclear weapon production facilities. Apparently that's why Germany's nuclear program in WWII never got off the ground, because they needed heavy water for their design, and only could source it from one factory in Norway. And the Norwegians deliberately sabotaged all the equipment so that Hitler was screwed. They all got shot, of course. Brave, brave men. They kinda saved the world a bit. Although Germany's nuclear program probably would have failed regardless because they killed or exiled all their top Jewish scientists, who had all gone to America to work on the manhattan project instead. I always wonder what would have happened if the bombs were dropped in Germany as originally intended. Like, Godzilla wouldn't exist. We'd have a German equivalent probably, called Gottzillanschneibenleifenstagreich or something. Anime wouldn't exist either, cos anime only exists because of the American occupation of Japan after World War II. So anime would be a German creation.
Anyway I digress. Heavy water sounds so cool as a name. I don't wanna try it myself, mind you. Not that I'd ever be able to get a hold of any lol. But yeah.
Actually, you would have about 10% more buoyancy in heavy water. The idea being that the water itself being heavier, means you don't displace as much. And, by the way...D2O is a poison. Many substances have an LD50, (yes, even "regular" water), however, if you drink 30% of your body mass of heavy water, you just hit the LD50 of heavy water.

This is actually quite an interesting video, when I worked offshore, we are taught that if we have an underwater gas blowout, DON'T jump into the water because you will sink. Also, on another point, there are theories that when huge tracts of frozen methane on the bottom of the ocean start to bubble, the density of the water above drops, and causes it to boil/bubble faster causing large areas of ocean to turn over. This was a theory of what causes ships in the Bermuda Triangle to disappear without a trace, that they lost buoyancy and sank.
Statistically you're *NO more likely* to sink in the Bermuda Triangle, than any other part of the Ocean.
Its just since its a part of major shipping routes, it gets more attention. Plus all of the click bait articles & videos & conspiracies have made it far bigger of a problem than it actually is.
That theory is absolutely terrifying. Just imagine being on a ship and the water around you starts to bubble intensely then you feel the ship begin to tilt. Fuck that's nightmare fuel.
@@erikcarrillo7378 Even more terrifying, is some would assume (I mean without the knowledge not ever seeing/hearing about this type of event) that the ship somehow created hole in the hull, and that's why it's sinking so quick. That panic, just to see that also every lifeboat is sinking because of the same event happening underneath them. 😱
This actually happens to a ship in a movie I saw recently, caused by a gas leak. It was pretty good imo. Called 'The Burning Sea'.
Just fyi statistically there isn’t an unusual number of lost vessels in the Bermuda Triangle compared to similar shipping lanes. There just aren’t any other islands between Bermuda and the Virgin Islands.
As someone who work with human waste every day, I’d just like to say that, even though you might not drown in the flow of “non-bouyant-poop-water”, the contamination will. Just dont take a swim in it. That is all.
I don't think I'd work near those vats without a harness and recovery rope, and I just assume they're over 12' deep. I do know you absolutely will sink in giant stills filled with booze.
Around ten years ago, I fell up to my neck in what I can only imagine were waste water sludge dumping pits (as it is right next to the water treatment facility). A very thick, gelatinous black sludge that I always referred to as the "nuclear waste dumps".
The top layer had frozen over in the winter so I was shoveling it off to skate on it, and right when I was in the middle of it the ice broke. Thankfully I was able to climb out of it somehow despite my heavy winter clothes, and made the trek back to my family's house through the below-freezing temperature. I need to email the facility and find out what that stuff was.
That's nasty and crazy glad you made it out okay, but sad you were dumb enough to try and ice skate over wastewater back then. Hopefully, you'll do better.
Non-buoyant water actually existed in mythology far back too. I remember a Chinese legend where Houyi (the guy who got exiled from heaven for doing his job because apparently the Jade Emperor, like most emperors, was really fucking bad at reasoning) had to cross a perpetually burning mountain full of fire and lava, as well as a *river with water that had no buoyancy* before scaling tall, treacherous cliffs with edges sharp as blades, which, at its peak, lived the god who brewed the elixir of immortality.

Your last statement is so true. When lives are on the line, the only correct direction to fudge the warning is in the direction of increased danger.

@@complainer406 wrong context. I'm not talking about waring people out with too many warnings. I'm talking about what decision a person makes when they don't know the true danger of something, and they're forced with potentially overstating, or understating, the danger.
And the decision is, in my opinion, simple. When you don't know what the true danger of something is, you err on the side of caution. Caution means you choose to overstate the warning, rather than understate it.
Quick clarification: the tanks you show at the beginning when you say "these tanks" are actually Secondary Clarifiers, where the aerated water goes to settle. The water in those tanks is no longer aerated and not "non-buoyant", only Aeration tanks that use diffusion bubblers on the bottom of the tanks to aerate the mixed liquor create the non-buoyant water.

When I was in primary school, we visited the local sewage treatment centre and were told about this. So, I was taught this as a young child and have never forgotten since. It's not hard a difficult concept to grasp.
I work in marine salvage and we were towing a junk barge that had "broke loose" because the company didn't want to dispose of it. Anyways stuff hit the fan and I was on the barge running pumps and compressors and because the seam split it went down fast. luckily I had a good life preserver because on instincts I ran to the bow where we'd been filling with compressed air. By the time I realized I'd done effed up it was too late. But I tried jumping in and getting away and I swam about 5ft before the water really started pushing air out😮 and I sank like a rock....life vest and all. it was no joke even though I laugh about it now because it felt like being inside a washing machine on spin cycle. I'd get close to the surface and then back down until luckily the barge turned sideways. I didn't know it at the time and I got in position and kicked off the deck far enough out of the devil's cauldron to pop to the surface where I blacked out and slept through most of my ambulance ride. But at least I was awake for the helicopter ride to Cooper😂 who were absolutely amazing❤

Yeah drowning in shit water that no matter how hard you try you can't swim in is nightmare fuel
Several gas platforms have sunk when they had a blow out at the seabed. Also sea bed land slides have sunk ships because of released gas pockets.
I went on a 5th grade field to a water treatment facility and when we went to look at one of the aeration tanks (idk if it was one or not) the person giving us the tour said that if you fell in you would drown because of the amount of bubble in the water. (I could be wrong as my memory is fuzzy)

Pretty cool! Good for you
Bruh, I am going to solve your mystery quite simply: When you drop a toothbrush in a toilet you've pretty much written off that toothbrush forever. I am pretty sure falling into a giant vat of poop water has the same effect on your desire to keep living. "Whelp, here I am in a sea of crap...guess I'll sink to the bottom and hope I do better in the next life"
agreed. Just like using 1-ply toilet paper which breaks making you scrape your asshole, that finger is gone.
I just laughed so hard at this comment. 😆😆😆😆😆
Y’all are too much 😆😆😆😆 keep up the good work fellas.
The irony is that studies show our bathrooms are often 'cleaner' than our kitchens, in a microbial sense. Toilet water isn't the risk people assume: it's usually drinking standard; the bowl is cleaned & disinfected more often than plenty of other areas in our homes & flushed on a regular basis.
In actual fact, in most North American Bathrooms, the toothbrush is dirtier than the toilet.
Your kitchen sink also, very likely, has a higher bacterial load than your toilet.
The moment Kyle started this presentation, I immediately thought about the MythBusters segment with Adam Savage being the test subject. I was so pleased when Kyle referenced those experiments. And while it was not mentioned here, Savage partially experienced the smaller tank what Kyle described at the 10:30 mark. He was pushed to the wall of the vinyl drum but the flow was not strong enough to to push down. In the swimming pool, the rig was far enough from the edge that Adam was not pushed that far.
"Up shit creek without a paddle" has a whole new meaning
I've always wondered what would happen if someone fell into a vat of vegetable oil or mineral oil. Since as we all know from elementary school science experiments oil is much less dense than water, and the humabn body is mostly water and thus has an average density similar to water, would a vat of processed kitchen oil be much more worthy of a warning sign like this?
kitchen oil is about 8% less dense. You wouldn't sink like a stone or anything but alot of people would be close to neutral bouyancy. Instead of just floating on your back or a very light treading you would really have to keep swimming moderately to keep your mouth in the air. So you'd be more likely to drown but if you were a reasonable swimmer and close enough to a way out you would likely be fine assuming you didn't panic.
You wouldn’t float. But you wouldn’t sink.
@@TheKiltach I see. Interesting.
@@TheKiltach Sounds about right.
I think a much denser ''liquid'' that would be impossible to swim in, would be something like syrup or honey.
@@denmark5354 You would swim just as well as normal. Although it's thicker, you get more force back when you kick/push the syrup. Mythbusters tried it out and found you swim just as well, no difference
I'd be more concerned about the medical risks of full body exposure to biohazardous waste.
Why don't they just put a big net or screen/mesh/grate over the tank? It would allow it to breathe, but not allow a person to fall in.
Probably hard to take of and put on every time you would want to clean it or something

2:39 Technically, the water bottle floats because the fluid it displaces has the SAME mass as the entire water bottle, not more mass. Balanced forces result in zero acceleration in the vertical dimension.
Indeed. I'm always surprised at how many people get confused when it comes to Archimedes principle.
Around 10% of an iceberg protrudes above the water...
Because when ice freezes, it gets about 10% bigger.
When an iceberg melts, all the water fits in the hole it made.
The melting of floating ice dies not affect water level, in any way.
@@1TwistedPoet What about the melting of ice that isn't already in the water? Ice on land? Don't you think the increase of volume through land-ice melting into the ocean would increase the water levels of the ocean?
@@quincycarra9107
Measure the size and thickness of the Ice Sheet you are concerned with.
Take the total area, in square kilometers.
Take the total area of the world's oceans.
Divide one by the other, to get the number of ice sheets, of that size, that it would take to cover the oceans.
Slice your ice pack horizontally into that many slices, and measure the thickness.
Adjust downward by 10% to account for the volume differences in water and ice, and THAT'S how much deeper the oceans would be...
Now, you also need to adjust downwards, slightly, to account for the fact that as the water gets deeper, it takes up, sometimes, significantly more area.
Like, if the ocean rises 1 metre...
Anything at an altitude of 1 metre or less above sea-level will now be underwater, increasing the surface area as it rises.
And remember, it will take decades for it all to melt, if it does. It's not the crisis you've been lead to believe.

Think critically and you can tell the difference between real research and facts, and when you are being fed a line of crap, with people waving "Science" in your face, too quickly for you to see it, and refusing to engage, publish or even acknowledge the existence of those that disagree.
You'll recognize it by Narrative.
When you look for the information in a wide variety of main stream sources, not only will the presented facts be the same... that much is common to good research...
But the actual words used in the report will be IDENTICAL.
The SAME words, in the same order. They are not investigating and reporting fact, they are copying over a script of an authorized Narrative.
Remember, Boys and Girls, you only need a Narrative when you are telling a STORY. When you speak the truth, FACTS speak for themselves.

There's a component of creating signage and iconography that must take into account the understanding of the layperson. The message must be clear and adequately convey the danger while assuming that the person reading the warning sign has little or no background knowledge.
Like the "high voltage" signage. You can split hairs about the actual danger of amperage vs voltage, but for the lay person "high voltage" is adequate. The issues discussed here about the aeration tanks are similar in my opinion. Sure, the real danger may be different than what the warning sign implies, but it really doesn't matter at the end of the day as long as the sign adequately impressed upon a lay person the relative danger.
Then you get the non english speaking trespassers complaining that the signs weren't in Icelandic or such.
@@ohasis8331 that's where the pictograms come in. Shouldn't need to read any particular language if the pictogram and icons used are well designed.
@@englematic True enough but I was being facetious sorry.
There's fine line at which you stop caring about saving idiots from themselves... "You will drown" is more than enough to anyone with a functioning brain. They don't have to know how it works, they were warned that they WILL drown.
Which is why I have an issue with "high voltage" and similar, you could easily send the same message by telling them that your hands will grip to the wire until your last breath.
there is a bit of a difference between a tank being filled with drinking water, and being filled with sewage. sewage or brown water is less dense than plain water, this is due the solids and dissolved particulates suspended in the water.
with the bubble heading up, you also get water from the top circulating down, almost like a rip tide affect.
the dissolved soluds and salts make sewage slighlty more dense than water

Solids suspended in water make it denser
@@itsgonnabeanaurfromme only if the solid is denser.
Thank you for this, loved it. The belief that sinking ships 'suck you down' comes from the loss of buoyancy caused by a ship full of air escaping underneath you - not so much aeration as big-ass bubbles - but even then, a guy who went down with the titanic and was on the outside of the stern railing when it went under says he didn't even get wet hair.

Anyone else first learn about Non-buoyant water from Metal Gear Solid 2? I was only 10 when I played it and I remember being so freaked out as Vamp (the boss) is explaining it's properties and how you just instantly died when you fell in.
This video stirred up memories from 18 years ago (May 2004) when the concrete dome that covered one of the digesters at the Spokane City Waste Water Treatment Plant collapsed dropping three men into the sludge severely injuring two and killing my father's best friend and coworker Mike Cmos Jr. The reason 3 men were on the dome was to clean it off so the houses above the treatment plant wouldn't complain about the plant looking dirty.
This was awesome. After watching, I thought, "hey there's a treatment plant I always pass. I remember seeing fire, and it smells. I wonder if it's anaerobic treatment?" So I went to my city's page and found the water pollution control, and was probably the first person to see that page in a long time. Sure enough, it's anaerobic treatment! With 3 treatment steps, after solid removals.
If you're seeing fire, then it's probably them using burning to get rid of their excess solids. The plant I work at uses a belt press feed system instead to run the waste sludge through a series of rollers to squeeze water out and then the final (mostly dry) product is dropped out on a big pad after being mixed with lime. It's then hauled away in trucks to be used in agriculture. The area around our ditch actually smells quite nice, b/c while the bugs eat the carbon in the solids they release nitrogen gas as their "waste product", which is slightly sweet smelling and just goes up and dissipates in the air.
Aerobic ones smell too, especially when you turn the blowers on to the digesters
I appreciate how you used diagrams of both trickling filter systems and activated sludge.
I work in this industry and nobody seems to find it interesting at all. They just complain about the smell
12:01 most biogas (the methane gas mixture that is released from the anaerobic digesters) isn’t “refined on site”, as it’s way too “dirty” of a gas.
Most WWTP, simply run the gas through extremely minuscule refinement (put through condensers, etc), then it is run through biogas engines to produce electricity. That biogas is still ~40%-60% methane (the remaining is CO2 and other gasses); making the gas unusable (far too dirty) for actual natural gas engines and producers.
I remember reading a study showing that the improvement in energy generation from converting biogas to methane was so slight that it made it not worthwhile to spend the energy cleaning it. Better just to use it as is.
Quite an informative video.
I like to think of this as aerated sand or Liquid Sand. Where, in sand, you blow air from beneath and it turns the solid sand into liquid-like and you start to drown. Hence, can be compared to this.
Whole different thing
L I Q U IDDDDDDDDDD!
Sand is interesting, behaves a lot like a liquid anyway.
@@dannypipewrench533 yesss
Imagine if there was a place on Earth where this had the same effect but with gravity and it would be possible for an unknowing victim to jump up and be shocked to find himself falling up to the sky.
I mean, if you fill an angler fish with excess air, they kinda would do that.
Nice idea! It would affect the air, too, which I imagine would make some violent weather!
H. G. Wells sort of imagined this in "The First Men in the Moon"--there's this imaginary substance called Cavorite that stops gravity, which the protagonists use to lift their spaceship. The first time they make a sheet of it, it causes this atmospheric fountain that sucks the Cavorite up the chimney. They speculate that if that hadn't happened it could have peeled the atmosphere off the Earth like an orange.
Eventually they're more careful and they make these sort of Venetian blinds out of it, which are mounted above and below their ship. When they want to go into space, they just close the blinds below the ship, cancel out the Earth's gravity and get pulled all the way to the Moon.
Jules Verne didn't like the story, he said "come on, Wells just made up an antigravity substance, that's cheating. I did all the math for my giant Moon cannon."
The high school I attended has a water treatment facility directly behind the track/football field with the tanks of shit being the closest structures to the school. The smell atrocious, and the staff would refer to it as our homefield advantage. After going on a trip to the plant and being above these pools of crap, we realized that it smells much worse on ground level than actually being right above it.
Was it in South Florida by any chance?
Incredible city planning right there lmao.
Then again, my city has the waste treatment plant on an island in the middle of the city. It would be prime real estate for an incredible house, business, or park, but nope. That's where we send the poop. You smell it every day driving over the bridge.
@@Theviewerdude wait, you DONT want to build your house in a massive vat of human waste?
That is because the gasses produced are heavier than the atmosphere which means that it it falls to ground level just like water does in an overflowing tub of water.
Bro, your videos are filled with fascinating information but so funny at the same time. You crack me up. Keep up the good work, my man!
Theres also this thing where during a ship sinking, the massive columns of air bubbles can form an oxygen elevator shaft that you can fall down through. Of course not talking about the bubbles in micro scale, but the big rolling bubbles that can be over 1-2 feet in diameter.
“…Massive columns of air bubbles can form an oxygen elevator shaft that you can fall down,” bro nice imagination but there’s no way that’s real, it’s a cartoon imagination
@@JamesChessman how so? all it is is just a stream of bubbles headed towards the surface. just because YOU cant imagine it doesnt make it not real.
I thought it was the undertow current from large voids in the ship being filled with water that causes the suction and sometimes unfortunately drowns people. The imagery of a column of bubbles lining up in such a way for a human to actually fall down through is interesting to think about. I guess it could happen, But they tell you to swim away from ships because of the potential undertow, I believe.
@@benwestphal4076 yes there's hydraulic forces that will suck you down too, but a large volume of air from escaping air pockets out of the ships - depending on the size of the bubbles literally make you fall through the water.
@@utley actually this was tested by Myth busters and it's FALSE. A sinking ship will not pull you down with it if you're on top of it. There's no "sinking bubbles" that'll cause you to be pulled under water when a ship is sinking.
The second I saw the thumbnail I thinked about Vamp's boss fight! Thanks for mentioning it, I was wondering if it was true since 12 years. Heck, I even remember my first encounter with him and being like "I love how this game justify everything". Other than that, very interesting video ! You are very clear with your explanations!

@@dannahbanana11235 yes exactly! Also seeing Vamp being so agile that he can swim into it was impressive
When I was in elementary school, we took a field trip to the water treatment plant. We got to tour the walkways of the tanks and what always stuck with me was being told that if you fell in the tank, you will get pulled down and drown because it's not buoyant. You can't swim in it without drowning. Still terrifies me.

I found the execution of this experiment to be quite poor. It would have been better not to include it in the video.
Sumps filters in aquariums run in the same principle. It is why we cycle aquariums before sticking in fish to get the beneficial bacteria in the filtration.
Interestingly, without it being a biohazard, the Mythbusters tested this some time ago with a large column of water they could float in but also inject large quantities of air in. They added air to froth up the water and down they sank. Turning the air back off again allowed them to float again.
Always liked the water and explosive episodes
I live in a town with a few different abandoned asbestos mines. The water at the bottom of the open pits are a beautiful cyan/blue, but the amount of minerals in the water make it so swimming in it is impossible.

Why is it impossible to swim there?
@@rakino4418 could be completely wrong but it could be the water is less dense causing a person to sink and be unable to rise in such water like how it’s hard to sink in the Dead Sea cause it has to much salt in it making it denser than most body’s of water

I’m a waste water operator. We did this test with clean water in the tank. One type of diffuser we used would push you up. The other types we used caused a current that would pull you under and slam you into the piping and tank bottom . Nice to see videos evolving water and wastewater treatment system.
Reminds me of when Mark Rober made a pool of sand that, when activated, would send air through the sand allowing you to move free in it as if it were a liquid.
As soon as I saw the title I was thinking of that part in Metal Gear Solid 2. The fact you referenced it has made my day.

''and so they can eat your poop'' reminds me of my little brother when i try to explain something serious and then everything just gets ruined by that interruption assigning my explanation to his joke
Gotta say even more outta pocket shit than he can. That's the key
Wastewater treatment is such an under-appreciated topic. I work in a lab that tests wastewater samples and part of what I do is measure the amount of biodegradable organic matter (i.e. poo) in pre-treatment and post-treatment samples. Spoiler alert, the aeration tanks are highly contaminated waters (and stink to high heaven - I warn my colleagues whenever I'm about to open a bottle of aeration tank sample!)
That's weird. Activated sludge shouldn't have any odour. Is this universal or from a specific plant? Are you maybe referring to the influent?
Toilet-to-tap leftist nonsense is probably going to ruin the rest of your career, the absolute insistence that process water become potable and served to people is so obviously political when I've got farmers on my system clamoring for more water, any water. But no, no, we have to drink the poopie water. They're actually doing that so that you get nowhere with everyone since if it became apparent that water is not oil and doesn't actually disappear into entropy a leftist somewhere might lose a job or some grant money. It's actually just political fraud perpetrated using every 4th grader's favorite thing, that's their use for you, that will be your 5 minutes on TV.
I'm so glad that you mentioned MGS2, that's the entire reason I've always been interested in this concept too.

The sand pit hot tub gives a good representation of aerated sand/water. It turned sand into a liquid like substance.
My god Kyle, not a single video lacks your expert quality, keep up the great work!
As a lifeguard, they are very dangerous, if you cannot float there is very little you can do to swim let alone get saved. It should only be used in a swimming capacity for diving where a damping is needed.
