Thanks for the education, Professor Kyle (♥️show). Question: Could dead animals in the drowning machine cause another 👉"spillover"👈 event? Pun intended ...but seriously, could it? 😳
I'm qualified to canoe grade A rapids here in South Africa. We're taught about these 'drowning machines' as part of the training. First prize is obviously to never get stuck in one of these but your best chance of escaping is actually to swim down and then out. The water closest to the river bottom flows the fastest without tumbling (you can see in the diagrams). Hopefully a useless bit of info but if it happens to save someone's life then it's worth it!
I am a rescue diver, and I am certified in swift water rescue. These drowning machines truly are as dangerous as this video indicates, probably even more so. These types of water rescue situations are often the worst cases we encounter. As the video stated, others that try to help end up caught in these washing machines. Sadly they often have tragic endings. Thank you so much for making this video and bringing awareness to this hazard.
How do you even rescue or recover someone from one of these? We have several of them on the river which flows through our county and people have drowned in them often.
It’s funny if we abandoned something on public property, we get sued Government does it, “eh give em a sign and some pabnflits” cuz you know wars have been lost cuz people didn’t print enough pabnflits
I got caught at the bottom of a waterfall like this once. Luckily I kept my head and thought the only way out was along the river bed. You have to dive down and push off away from the fall. I almost drowned but was able to use the huge river rocks to pull misled far enough away from the fall base that I could swim again. If you just try to swim you’ll tire and drown. Doing the exact opposite of what your body is telling you to do is really terrifying.
I live near a river which has many old low water dams across it. It's very good advice to stay well away from them if swimming or tubing. I remember somewhere around 20 years ago a guy died trying to kayak over one. He got caught in the vortex and drowned.
Glad I'm not the only one who thought this. I was thinking a machine that's submerged in water, and can't be removed, which causes all machinery within a certain radius around it to start drowning. Like, full-on spontaneous generation of the same type of liquid in which it resides, which could easily be manipulated (so long as no less than a small %age of the original liquid remains) by replacing it with whatever liquid the tester can think of. This could easily solve several societal woes (water shortages, blood shortages, food shortages [so long as that food is liquid-based]), but too bad, because the Foundation MUST maintain secrecy. If we wanna go darker, we could also have a small % chance of a small %age of machines within its aoe become fully-functional copies of itself, with it having the innate "understanding" that machinery means *anything* man-made, [*DATA EXPLUNGED].

I nearly died in one of these. There was a concrete bowl under the water at the bottom of a dam, we would "ride" around in the bowl which was like 3 feet deep on the slap of concrete, but one time I slid down the damn and missed the slap and landed beside the bowl where it was about 15 feet deep. I remember being tossed around under water for something like 45 seconds to over a minute, I was at that very last second where I ran out of breathe and started inhaling water , and that was when I was shot up to the surface and when I got to the surface, I was about 150 feet downstream and was at the rivers edge. Someone above was looking out for me that day cause I honestly should be dead. I never went back in that river and I'm afraid of swimming now. Sadly someone died in that very spot the next summer. Caledonia ontario canada.
A commonality I’ve found amongst ppl in the comments who have survived drowning machines is that either they swam down, using the force of their legs to push off the bottom/the wall of the dam to get out, or they were launched out of the vortex after going limp. It’s crazy how the two best ways to avoid drowning in this situation is swimming AWAY from the surface or just doing nothing lmao
Yes Jesus Christ was looking out for you and me and my family by keeping us from going over the crescent of a low head dam. He's faithful to save. Even save us for all of eternity. Romans 10:9
Cheryl M - i think they mean a ramp from the bottom point up in direction of water flow... a literal rock ramp. We have them here in SC for this reason at some dams and they mitigate the jump effect substantially.
@@casedistorted Why? We have 1 land bridge here in WA, over I-90. It cost millions of dollars to construct when only a handful of animals actually use it. Why waste millions of dollars on something like that which has no real benefit. A better solution would be to build a deer fence. Much cheaper, much more effective, can protect a larger portion of highway, requires minimal maintenance, easy and cheap to repair, and more visually appealing as most people probably won't even notice it.
To be fair, as a fellow Niagaran, most of the Niagara river is essentially a 'drowning machine.' Class 6 and class 5 rapids downstream, and the rapids + control dam upstream of the waterfall.
You know, I have one simple request, and that is to have sharks with frickin laser beams attached to their heads... Swirling eternally in a drowned jump.
My father got caught in one when he was a kid. He remembers being sucked down and being unable to escape, running out of breath, and then nothing. The people he was with saw him pop back up far away and rescued him. When he went limp as he started to drown and fell unconscious, he stopped struggling and the water just spat him out like a watermelon seed.
@@absolarix Look at their username and pfp of Fidel Castro. Communism is without debate, by far the most deadly ideology in history. You and I wouldn't be tolerating a fascist in the comments section, yet somehow a communist is OK by you?? Even though communism has killed over 16.5x more people than fascism
@@spaghetti-zc5on LOL. Over 100 million people (at a low estimate) have been killed by communism.. To put it into perspective, fascism has killed 4 million. They're both equally evil ideologies, but one has had way more destructive effect than the other. Why does that one get a pass, but the other doesn't?
If it was, why was there so many famines in communist countries? Why did all communist countries embrace the free market (except for North Korea and Cuba, but these are shit show). Communism isn't fine
Taking off a life vest and paddling all around and hoping to get spat out is a persons best hope, the victim might sink deep enough into the fast flowing water at the deepest point and get spat out before they float up again. They have drowned rescue specialists trying to get trapped people out of them though, there are videos of inland coastguard boats trying to rescue people and unfortunately they end up in the water when the boat hits a cavitation zone and lost buoyancy and tipped the rescuers into the water who also become victims. It really isn't something someone should try, or place themselves in the risk of an accident placing someone in one.
Yeah, sure. "Challenge accepted" it, idiot. It's so disturbing to think, that given stupid things people will do just for attention today, i believe 100% that there is someone out there who will actually say this and do it.
Great explanation. My friend got into a drowning machine ( in Germany we call them washing machine). He was in the German underwater rugby national team at that time. He is a very experienced swimmer/diver/freediver and about as good as you will ever get for this kind of thing. The only reason he survived was our friends used a rope and someone went in and got him out after he became unconscious after maybe 3-4 minutes of fighting it. They had to do 20min of cpr before the ambulance arrived. He made it without any longtime issues. But if you get into this there is no escape without outside help and the helper needs to know what he is doing!
My great uncle drowned in one during the 80s. The motor on his fishing boat gave out, and he stayed to save the boat while his friends swam for shore. After going over the weir, he was repeatedly slammed into rebar at the bottom of the water. They said the motor started just as the boat went over. His bloated body was found a couple days later.
Victims: in order of priority 1. try to stroke perpendicular to the current 2. pray the sides aren't vertical - you AREN'T going to have the energy to do much other than roll onto a gentle beach. 3. don't give up - every second you sucessfully fight it is another second for rescuers to help There's your 2.3% increase in survival - that's all a book can help on that one. Rescuers: in order of preference. 0. turn off the water flow (If it's a spillway, you might actually be able to) 1. get a boat. 2. pull the victim to shore with a rope or pole 3. if (and only if) you are an experienced diver, with a support team, tie a rope under your shoulders, swim out and wrap around the victim - then pray your support team can haul you in before you are as screwed as the original victim. Good Luck, it's been an honor, sir.
i surf in lagoons that fill up with water on high tides and release a flow back out to the sea at low tides. the flow lasts about 40 minutes and they make standing waves in the rivers.sometimes they form drowning machines. usually the bottom changes enough to release you before you drown. i saw a friend caught for over 40 seconds and go blue in the face. another person jumped in and knocked them free / as your getting sucked down river underwater you feel the bad ones that are drowning machines pull you upward as you go through the back side of the flow . through manipulation of your body opening up and crunching into a ball or dive position you can sometimes pop out of the washing machine i went for 2 or 3 cycles on a big river that had 3 meter stranding waves got lucky layed sideways as i went over and punched out the back with a dive move throwing my boogie right as i went through the back.some hydraulics are inescapable but this might help someone escape in a borderline situation
Wait a second. Those rules apply to riptides. I feel the need to stress how unsafe submerged weirs are. You will not escape. The water has far too much air incorporated into it and that significantly reduces your buoyancy. Avoid these at all costs. Also, if you are caught in a riptide, do NOT FIGHT THE CURRENT. Every second that you do that wastes energy. If you submit to that urge, it significantly reduces your chances for a successful recovery. Swim parallel to the shore, or even let the riptide cary you out. The current gets dramatically weaker about 30 meters from the shore. Once you get out there, all you need to do is swim parallel for a bit (no more than 5 meters is necessary), then swim back to shore.
@@VibesOfVinegar yes, they do, only at a weir the current is trying to drag you down instead of out. And yes, you probably won't survive a weir flume - but you might get lucky, if you try. (Stay out of them, but if you find your self in one, that's your best chance, and that's still not a good chance)
Once when I was a child I was pulled out by the riptide and wasn’t aware that you should swim perpendicularly, do I swam to shore with my boogie board and after 5 minutes I was able to reach my uncle who was also boogie boarding way out from shore. After seeing him I felt relieved and we swam together back to shore
@@muninrob Darling, I am studying for a degree in engineering with a specialty in fluid dynamics. Everything you said to do does not help the victim, and may even hurt them.
Was caught in a riptide (natural drowning machine) when I was 3-4 years old, my dad's best friend (who was an active EMT at the time) swam out to save me, almost died himself. I can still remember when he got to me, even at that age, I could tell he was scared also and even tho I was almost at the point of exhaustion after being pulled under water several times I did everything I could to kick my legs and help him. When we got to shore he immediately collapsed on the sand and I ran to my mom (who was sunbathing at the time). In listening to him recount the story, I would later go on to find out that he did in fact almost drown himself. He said he was almost certain he couldn't make the swim back and had he only had himself to worry about he surely wouldn't have been able to summon the strength to fight through it. I was terrified of leaving the shallow end at pools for many years after that. I'm a very strong swimmer now and get kind of a kick out of treading water in the "danger zone" at wave pools for as long as I can.
When I saw the title I thought that they were man made machines specifically designed to make sure you would have the smallest chance of escaping from drowning possible once inside. Like damn who green lit that?
I got caught in a natural "drowning machine" at a small water fall I was swimming around. The ultra strong current kept pulling me and without anything to grab, I planted my feet and jumped out past where the water fell and hit the lower pool of water. I went under and swam back up giving my friends the thumbs up until I was out of nowhere sucked underneath without warning. I got lucky because it was a very shallow drowning machine so it pushed me to the bottom and out and away from the waterfall. I was absolutely fine but I know there were many ways that could have gone and none of them were good. My advice, don't panic, just hold your breath and be patient. Even if you think you're in the clear, keep swimming away because it can suck you back under.
A waterfall is one thing, but in our local river there are many low water dams which are quite dangerous. The best advice is to stay well clear of them.
I almost drowned in one of these drowning machines, but I was saved by a person with a lifeboat. He grabbed me and pulled me out of the water. Edit 1: He used proper equipment and was trained! Edit 2: I would like to explain what happened once again, but this time with more details. I was in an aquapark. One of its attractions was designed very badly and therefore it was very dangerous. It created a drowning machine. A lifeguard was and still is always on guard there because of the dangerous design. When I got caught in the machine he saw me and used a lifeboat and a special stick, that I can't remember the name of, to save me. The design is still the same but luckily no one has died in the park as far as I know, but some people got hurt there. Not only can you drown, but you can also physically hurt yourself, because of the bad design. That is by far the most dangerous attraction in the park and a lifeguard is always there to ensure the safety of the people. Still the design of this place might claim a life one day. I still visit the park every summer, but now I am more careful around this specific attraction. Also if you are asking yourself why am I going in an aquapark in the middle of a pandemic, to you I say that in my country we actually did social distancing and the summer the cases per day were so low (7 per day), that the government reopened everything. Edit 3: Grammar. Edit 4: So many people are asking why does the attraction still work, if it is so dangerous. They actually did some things after my accident. First, now there is always a lifeguard on duty. Before there wasn't. I got lucky that one passed by and saw me. Second is that they changed the boats so it is harder to fall in the water. That's all. The problem is that there is no warning sign to this day. You should know that the design is dangerous, otherwise you will be saved by a lifeguard just like me (at least now there always is one). The design simply is bad and really maybe I should have sued them, but I forgot to mention that I was a small kid when this happened. I thought I simply wasn't a good swimmer. After I grew up I understood it wasn't my fault. I heard that the park actually got sued for this attraction by someone else. That's why now there is always a lifeguard. This is the only dangerous attraction. Everything else is safe. I think that when it was designed, people thought, that no one will fall of the boats. But I did. I survived and didn't sue them. I also didn't tell my parents until the next time we visited the park, which was over a year later. People regularly still fall off the boats. Most of them don't get caught in the machine and simply forget. The few that do are saved immediately now and there is no danger NOW. Before there was. I'd also like to mention that this is by far the SAFEST aquapark in Bulgaria I've been to. I had it easy, because this year my brother actually broke his foot in a different aquapark. The aquapark has already been sued multiple times for being too unsafe (mostly people who broke a bone). My brother fully recovered and is ok, and now you Americans know how bad safety is in most aquaparks here in Bulgaria. Now please let my fingers rest. Bad design! That's it. The designers forget the human factor. Also I would say, that when my brother broke his foot, it was mostly his fault. He was being reckless. That's why we (me and my brother) didn't sue them. Still safety in this aquapark is a low priority. All I say is that my brother is the only one responsible, for breaking his foot. Ok I am done. Please don't ask me any questions! Edit 5: I have Covid now. Edit 6: I have recovered (not fully, because I cannot smell or taste anything).
@@shroomer3867 yeah of course, thats the one advantage of the internet. I bet I would be a real stupid piece of shit if I'd live in a time were I had to go to a library to learn stuff! hahah
@@kylestanley7843 yessir but its still a mildly terrifying one lol jesus I'd never want to get stuck on a washing machine 😭 forever getting hit with sticks or other items. Thats just a big OOF.
canoeing is one of the most spiritual and amazing things to do... just learn the waters and used the safety gear PFD, follow the safety codes... I live in Bristol UK .. when the water warms up..... come along.... let's paddle together... please never go near one of these... the more knowledge and safe practice the more you can enjoy the waters...
Where I come from we call the "Drowning Machine" an undertow. I used to fish on a dam at Bernadotte IL like he mentioned. If you entered the river about 25 meters down stream from the damn and started wading towards it you would eventually start to feel the water pull you up stream, that's when you know to stop. There's been times I've seen logs and other debris roll around in the "dead zone" for a couple weeks before the river lowered (slower current) or raised (faster current) that would send it down stream. They are no joke. Word of advice, if you see a bulge in river water and the surface is roiling, avoid it. It could be an undertow. Side note, the Dam at Bernadotte was constructed for a WW2 camp called Camp Ellis for training and a POW facility. Interesting history if you're in to it.
Those are separate things. The drowning machine is the weir itself and the tumbling water at the bottom. The undertow is the undertow- an underwater current that travels "backwards" from the waves or current on top. If you ever swim in the ocean, you'll feel it if you're near shore every time a wave breaks and then pulls back though unless it's really rough and waves are large, it generally isn't strong enough to bother you or be dangerous.
@@Project2457official Wrong. Undertows don't kill people specifically. They are dangerous because people caught in them don't know what to do, panic and drown. Or they try to swim against it and tire out and drown. But the actual drowning part isn't caused by the undertow itself. Undertows are also easy to get out of as they are small. They are also temporary.
There is one of these after the “falls” at my grandpas. It was fun to get pinned underneath because I liked practicing my breath holds. I only had the confidence to do so because getting out is as easy as hugging the bottom. I understand how dangerous it can be to someone uneducated or in a panic. Kind of disturbing that I used to do this unsupervised as a kid though
As I assume anyone watching Kyle Hill has probably heard of multiverse theory, I'd like to say that there are probably many, many parallel universes where you died in a drowning machine.
I also got caught in a hydraulic jump when I was about 8 years old, the water was forcing me down with so much pressure I could not swim up to the surface it was like having someone sitting in your shoulder while trying to swim up wards !! But someone saw me and pulled me out thank God !!
@@imjustmetoo7419 Lmao God was the one who made the person see that this guy was about to drown. If God ignored This guy, he would have let him drown and not Make the person who saw him drown in the first place see him
Yea, I havenever seen a "drowning machine" sign in the US near a dam or high water road crossing/spillway warning, Just danger signs , risk of drowning, do not swim, etc. Key thing is don't swim or raft near a dam or go into a flowing spillway.
The local river here has plenty of dangerous low water dams, but I've never heard them called drowning machines or seen signs like that. In fact, there are no warning signs at all.
I haven't been stuck in a Drowning Machine, but I've done the surfer's almost-equivalent: wiping out with really poor timing on the first wave of a big set and having the next three breakers land on your head one after the other. One of those moments where you seriously feel like there maybe aren't going to be any more moments.
I love swimming, but there is nothing worse than bad timing a set of waves. Whenever they say calm heads prevail, I think of the times I have come up for air only to meet resistance or more water. You just have to rally, time it, and find it. Nothing like the rush of another chance.
dude this exact thing happened to me i felt my body contort to the wave and i really couldn’t get out, i relaxed a bit and let the waves wash me up on the beach, what was like 30-40 seconds felt like my life flashing before my eyes
I heard from a diver for the core of engineers if you’re ever caught in that turbulence swim strain towards the bottom as far as you can go then strait out
Similar idea to swimmers caught in whirlpools. Swim with the spin as fast as you can for two revolutions - even though you're being sucked down - so you can use more momentum when you try to burst outward. Although, of course, it's better to recognize and avoid a whirlpool before you get sucked too close.
That's correct! The water flowing out of the drowing machine is at the bottom, the water flowing in is at the top! So the only way to get out is to get to the bottom and then swim as hard as you can along it.
There were several of these dam on the small river in my town that were used to power/run the various old mills, however since the mills had all been closed for decades, while I was in highschool it was decided to remove them after a large spike of deaths occurred over 2-3 years including 3 of my classmates. They are incredibly deceptive too as the one here that claimed the most lives could just barely be seen if you looked at it head on when going up stream but if you were going down stream then it's be invisible until you were right on top of it at which point you'd get sucked in and stay there.
@@DeathSabr3 I don't understand that in today's day and age, where 'safety' is such a buzzword thing, they wouldn't make these dams safe. I mean, it's not like it's fucking rocket science or anything to just design a dam that either doesn't have a drowning machine or has safety mechanisms that prevent you from getting stuck in one... It does probably cost a bit more money though.. which just goes to show you how much a human life is áctually worth. :)
@@ayporos oh I agree. The community i live in is much more invested in putting every last tax dollar into their football programs and bibles rather than listening to a scientist or think of other people's safety
@@ayporos Perhaps put a fence in the water or a net that just makes it impossible for people to cross the threshold without noticing. I dunno at least that sounds like a cheap easy to do fix for that situation but I'm no engineer.
There's actually one of those low dams at a nearby river where I live. It's completely unmarked though because it's incredibly shallow, and you can stand in where the actual vortex is just fine. I actually got caught it it briefly once as a toddler because I was itty bitty, but my parents were always watching when we were next to it. Interesting how if the water was a bit deeper, I could have easily died. One of my common play places as a child.
This sounds like a joke, it's not. I tried it once as a kid. My friend smoked some of this stuff and described to me me how he went on a ten minute adventure into the floor. I smoked some too, and all that happened to me was that I became convinced that my friend had called the cops, so I hid in the bathroom. At the time, salvia was totally legal.
@@TheRusty In non-Euclidean geometry a circle doesn't have to have 360 degrees. If it has more, you could spin around multiple times and still not reach the direction you were facing when you started. If it has less, you could potentially see in every direction around yourself (in front, the sides, behind) at the same time by looking straight ahead. Crazy stuff.
This freaks me out in hindsight as I go fishing at a local resovior and I would stand on a low head dam to get fish. I couldn’t imagine what would happen if I fell over the other side, this is a certain type of hell.
The scary part is if you get cought in something like this, you have to go against your intuition and try to go deeper into the water which actually forces you away from the dam. Any attempts of going up meets you with reverse current which again pushes you back to the dam and the vortex
Stand User in the Crowd, hopefully in the future we are responsible time travellers and block all access to 2020. I’m sure that’ll lead to some people using jail broken time travel machines to circumvent the block, but it should deter the vast majority of time travellers. On a side note, what if 2020 is the way it is because of some irresponsible time travellers?
I went over one of those damns in Colorado about 5 years ago, scariest experience of my life. Luckily I had a life jacket and got churned out somehow. Would not recommend, 0/10
I went over something like a dam it wasn’t as intense but atleast I had a life jacket on. I was trying to go down it backwards on a tube because I thought that was smart and fun. I got flipped and I could feel myself being sucked under even with the life jacket. I lost my paddle though
I had been over it 4 times before going straight that’s why I went backwards but my uncle who brought me on it said he once went over it without a life jacket and almost drowned so he uses life jackets when he goes on rivers now. And he isn’t one of those safe people he doesn’t even wear masks or use sunscreen unless told so that just tells you how bad it was.
It's really cool how your theme of deadly science is reflected in the lab "setting" your series takes place in. If you ever run out of ideas, it would be super cool to see you analyze famous fictional sci-fi like Jurassic Park or Half Life or ALIEN and see how close it got to science fact, and if tech in those stories could feasibly exist at some point
0:02 As the administrator Me: Of what? Kyle: Facility filled with dangerous machines, laboratory equipment and non-eucledian organisms that defy traditional classification. Me: THE SCP FOUNDATION!!! Hes the adminstrator!!
When I was little I was caught in one of these low head dams drowning machine. I just got extremely lucky and grabbed super heavy rocks at the bottom and crawled my way out
These are also known as "holes" in the kayaking scene. I guess it's pretty obvious why they call them this way. They not only form artificially at dams but also in nature. Fast flowing rivers with big rocks in them. If you go kayaking in dangerous rivers, you know these are absolutely everywhere and are extremely dangerous for the ones who fall in and the rescuers.
So there are a few rescue techniques that we learn in kayaking for getting people out of “holes” (whitewater terminology for one of these types of hydraulics). Most of them involve reaching in with a solid object (paddle, typically) to try and give them something to grab if you can get close without entering the water yourself. Throw ropes aren’t recommended because they will circulate around the victim and potentially tangle them up with something under the water and make things worse. The best one (by sheer coolness factor), though, is a last-ditch rescue called a “live bait” rescue. By attaching a rope to the back of a rescue pfd (which has a quick release loop for such things) a rescuer can jump into the hydraulic, grab the victim, and then get pulled out by friends on shore. This is risky, for the same reason that throw ropes are, but allows you to keep the rope more taught and is easier to get the victim attached (especially if they’re disoriented and/or unconscious). I don’t recommend anyone without training try this, as it is risky for sure, but it is a cool thing to know about.
From what I've heard, there are a small amount of these "Drowning Machines" that occur naturally. One of these is in quite a wild rafting route in Norway.
As I mentioned in my own comment, the coral reef surrounding Guam causes one of these, and also consequently is an underwater meat grinder because of said razor sharp reef.
I love how this comes across as a kids science TV show and then at 5:50 shows the increasing fatalities over recent years and is in general about a DROWNING MACHINE :)
I guess I'm one of the only survivors of a drowning machine!! When I was around 18 I was taking a walk on a bike path by a river in Fort Collins, Colorado. I decided to take a swim in a part of the river that was upwards of a small damn which had 2 divots (the drowning machines) on either side of a small ramp that the water flowed down. The water that I was swimming in was very slow, so I wasn't that worried about getting caught up in the stream. Well, then there goes my dumb but, just lazily floating on my back for fun, I feel like I'm picking up speed. I had floated down stream to one of the divots, where I could see that the water rushing over the edge looked very violent. Unfortunately for me I was to late to swim out of the current and I had lodged myself into the divot. With only my arms holding me against the damn, the water pressure was trying to push me over the edge, I remember the water rushing over my body and head, making a small space of air where I could still breathe without drowning. I could lift up my head but the water pressure kept me from breaching the surface for long, luckily I was able to yell for help and some other people out on walks heard me, and tried to help. They couldn't really help ofcourse, so I had to let go of the damn and let the water push me over the edge. Lucky for me that the drop was only 4/5 feet deep, and I could easily stand in the shallow hole. I swam out and have been mentally scarred since. Edit: I don't remember if they had the sign out there though
There is also another one you could make a video about. My father worked at wastewater plants for 30 years. The aerator tank. It's one that holds about as much water as two or three typical swimming pools, with many tanks beside eachother... same size over. (Greatly depends on plant size. He worked at a 5MG per day plant) They have huge air pumps with pipes under mounted on the bottom, they are designed to separate solids from the waste so the "sludge" can be pumped out and processed later. When the aerators are on its pretty wicked looking. The way it rolls the water. My dad used to do demonstrations for videos dropping a basketball in a simulated tank. It will sink to the bottom immediately. As would a human. You cannot swim in a aerated tank. All the airbubbles create dead space and you sink like an anchor. I used to go onto the catwalk all the time to see it working. Another fun fact. My dad designed the most commonly used programing at SBR wastewater plants used today. And also developed one of the best aerator systems and was close friends with one of the developing fathers of the SBR plants creation. In fact. My middle name was named after him. He wrote many books back in the 60s and 70s developing it. As well as studying the types of bacteria to insert to "digest" the poop
@@CEbbinghaus what level of aeration is it? What CFM? What type of distribution? Tank size? It's not a hard experiment to set up with a fish tank. If you think you are an expert after watching a video of it being OK
@Cebbinghaus mildly aerated tanks are fine. It's like saying heat melts steel. What steel and what level of heat? The aerated tanks have to work at SBR plants. That's what makes poop and other solids SINK, so it can get sent to a digester or belt system to remove it. Otherwise it all floats.
I was an avid whitewater kayaker in college, and that is exactly what we called low-head dams, or any unnaturally straight ledge with no easy exit at the sides. Smaller ones were also called "keeper holes". The most dangerous ones looked deceptively calm. If you don't know the river, scouting and river-reading skills are a must.

I went white water rafting when I was a kid, and I remember there was a part of the river where we had to row to shore, walk down a slope with our raft and everything, and then get back into the river farther upstream. And it was exactly because of the hydraulic jump that caused all the air bubbles. They pointed the “drowning machine” out to us and said “if you go into there you will literally drown in air. A couple years later, apparently someone wasn’t able to get to the shore before they went over the fall and they ended up drowning. I think about that a lot.

I got caught at the bottom of a waterfall like this once. Luckily I kept my head and thought the only way out was along the river bed. You have to dive down and push off away from the fall. I almost drowned but was able to use the huge river rocks to pull misled far enough away from the fall base that I could swim again. If you just try to swim you’ll tire and drown.

Glad I'm not the only one who thought this. I was thinking a machine that's submerged in water, and can't be removed, which causes all machinery within a certain radius around it to start drowning. Like, full-on spontaneous generation of the same type of liquid in which it resides, which could easily be manipulated (so long as no less than a small %age of the original liquid remains) by replacing it with whatever liquid the tester can think of. This could easily solve several societal woes (water shortages, blood shortages, food shortages [so long as that food is liquid-based]), but too bad, because the Foundation MUST maintain secrecy.
If we wanna go darker, we could also have a small % chance of a small %age of machines within its aoe become fully-functional copies of itself, with it having the innate "understanding" that machinery means *anything* man-made, [*DATA EXPLUNGED].

I nearly died in one of these. There was a concrete bowl under the water at the bottom of a dam, we would "ride" around in the bowl which was like 3 feet deep on the slap of concrete, but one time I slid down the damn and missed the slap and landed beside the bowl where it was about 15 feet deep. I remember being tossed around under water for something like 45 seconds to over a minute, I was at that very last second where I ran out of breathe and started inhaling water , and that was when I was shot up to the surface and when I got to the surface, I was about 150 feet downstream and was at the rivers edge. Someone above was looking out for me that day cause I honestly should be dead. I never went back in that river and I'm afraid of swimming now. Sadly someone died in that very spot the next summer. Caledonia ontario canada.
A commonality I’ve found amongst ppl in the comments who have survived drowning machines is that either they swam down, using the force of their legs to push off the bottom/the wall of the dam to get out, or they were launched out of the vortex after going limp. It’s crazy how the two best ways to avoid drowning in this situation is swimming AWAY from the surface or just doing nothing lmao

Taking off a life vest and paddling all around and hoping to get spat out is a persons best hope, the victim might sink deep enough into the fast flowing water at the deepest point and get spat out before they float up again. They have drowned rescue specialists trying to get trapped people out of them though, there are videos of inland coastguard boats trying to rescue people and unfortunately they end up in the water when the boat hits a cavitation zone and lost buoyancy and tipped the rescuers into the water who also become victims. It really isn't something someone should try, or place themselves in the risk of an accident placing someone in one.

Great explanation. My friend got into a drowning machine ( in Germany we call them washing machine). He was in the German underwater rugby national team at that time. He is a very experienced swimmer/diver/freediver and about as good as you will ever get for this kind of thing. The only reason he survived was our friends used a rope and someone went in and got him out after he became unconscious after maybe 3-4 minutes of fighting it. They had to do 20min of cpr before the ambulance arrived. He made it without any longtime issues. But if you get into this there is no escape without outside help and the helper needs to know what he is doing!
My great uncle drowned in one during the 80s. The motor on his fishing boat gave out, and he stayed to save the boat while his friends swam for shore. After going over the weir, he was repeatedly slammed into rebar at the bottom of the water. They said the motor started just as the boat went over. His bloated body was found a couple days later.

1. try to stroke perpendicular to the current
2. pray the sides aren't vertical - you AREN'T going to have the energy to do much other than roll onto a gentle beach.
3. don't give up - every second you sucessfully fight it is another second for rescuers to help
There's your 2.3% increase in survival - that's all a book can help on that one.
Rescuers: in order of preference.
0. turn off the water flow (If it's a spillway, you might actually be able to)
1. get a boat.
2. pull the victim to shore with a rope or pole
3. if (and only if) you are an experienced diver, with a support team, tie a rope under your shoulders, swim out and wrap around the victim - then pray your support team can haul you in before you are as screwed as the original victim.
Good Luck, it's been an honor, sir.
i surf in lagoons that fill up with water on high tides and release a flow back out to the sea at low tides. the flow lasts about 40 minutes and they make standing waves in the rivers.sometimes they form drowning machines. usually the bottom changes enough to release you before you drown. i saw a friend caught for over 40 seconds and go blue in the face. another person jumped in and knocked them free / as your getting sucked down river underwater you feel the bad ones that are drowning machines pull you upward as you go through the back side of the flow . through manipulation of your body opening up and crunching into a ball or dive position you can sometimes pop out of the washing machine i went for 2 or 3 cycles on a big river that had 3 meter stranding waves got lucky layed sideways as i went over and punched out the back with a dive move throwing my boogie right as i went through the back.some hydraulics are inescapable but this might help someone escape in a borderline situation
Wait a second. Those rules apply to riptides. I feel the need to stress how unsafe submerged weirs are. You will not escape. The water has far too much air incorporated into it and that significantly reduces your buoyancy. Avoid these at all costs.
Also, if you are caught in a riptide, do NOT FIGHT THE CURRENT. Every second that you do that wastes energy. If you submit to that urge, it significantly reduces your chances for a successful recovery. Swim parallel to the shore, or even let the riptide cary you out. The current gets dramatically weaker about 30 meters from the shore. Once you get out there, all you need to do is swim parallel for a bit (no more than 5 meters is necessary), then swim back to shore.
@@VibesOfVinegar yes, they do, only at a weir the current is trying to drag you down instead of out. And yes, you probably won't survive a weir flume - but you might get lucky, if you try. (Stay out of them, but if you find your self in one, that's your best chance, and that's still not a good chance)
Once when I was a child I was pulled out by the riptide and wasn’t aware that you should swim perpendicularly, do I swam to shore with my boogie board and after 5 minutes I was able to reach my uncle who was also boogie boarding way out from shore. After seeing him I felt relieved and we swam together back to shore

Honestly tho
Was caught in a riptide (natural drowning machine) when I was 3-4 years old, my dad's best friend (who was an active EMT at the time) swam out to save me, almost died himself. I can still remember when he got to me, even at that age, I could tell he was scared also and even tho I was almost at the point of exhaustion after being pulled under water several times I did everything I could to kick my legs and help him. When we got to shore he immediately collapsed on the sand and I ran to my mom (who was sunbathing at the time). In listening to him recount the story, I would later go on to find out that he did in fact almost drown himself. He said he was almost certain he couldn't make the swim back and had he only had himself to worry about he surely wouldn't have been able to summon the strength to fight through it. I was terrified of leaving the shallow end at pools for many years after that.
I'm a very strong swimmer now and get kind of a kick out of treading water in the "danger zone" at wave pools for as long as I can.
When I saw the title I thought that they were man made machines specifically designed to make sure you would have the smallest chance of escaping from drowning possible once inside. Like damn who green lit that?
well they're man made and you haven't a sliver of a chance to get out of them so yeah you'd be right
While not intentional or malicious, you are still 100% correct.
well...you're not wrong
@@jeffwei yeah lol
Thats what i thought too
I got caught in a natural "drowning machine" at a small water fall I was swimming around. The ultra strong current kept pulling me and without anything to grab, I planted my feet and jumped out past where the water fell and hit the lower pool of water. I went under and swam back up giving my friends the thumbs up until I was out of nowhere sucked underneath without warning. I got lucky because it was a very shallow drowning machine so it pushed me to the bottom and out and away from the waterfall. I was absolutely fine but I know there were many ways that could have gone and none of them were good. My advice, don't panic, just hold your breath and be patient. Even if you think you're in the clear, keep swimming away because it can suck you back under.
@@lotusmau9062 Then you shouldn't be near drowning machines in the first place.
"I survived and all you get is this comment"
A waterfall is one thing, but in our local river there are many low water dams which are quite dangerous. The best advice is to stay well clear of them.
Riptides, baby, I narrowly escaped one in Cali once
Sounds like riptides from where I’m from but they just pull you out.
I almost drowned in one of these drowning machines, but I was saved by a person with a lifeboat. He grabbed me and pulled me out of the water.
Edit 1: He used proper equipment and was trained!
Edit 2: I would like to explain what happened once again, but this time with more details. I was in an aquapark. One of its attractions was designed very badly and therefore it was very dangerous. It created a drowning machine. A lifeguard was and still is always on guard there because of the dangerous design. When I got caught in the machine he saw me and used a lifeboat and a special stick, that I can't remember the name of, to save me. The design is still the same but luckily no one has died in the park as far as I know, but some people got hurt there. Not only can you drown, but you can also physically hurt yourself, because of the bad design. That is by far the most dangerous attraction in the park and a lifeguard is always there to ensure the safety of the people. Still the design of this place might claim a life one day. I still visit the park every summer, but now I am more careful around this specific attraction. Also if you are asking yourself why am I going in an aquapark in the middle of a pandemic, to you I say that in my country we actually did social distancing and the summer the cases per day were so low (7 per day), that the government reopened everything.
Edit 3: Grammar.
Edit 4: So many people are asking why does the attraction still work, if it is so dangerous. They actually did some things after my accident. First, now there is always a lifeguard on duty. Before there wasn't. I got lucky that one passed by and saw me. Second is that they changed the boats so it is harder to fall in the water. That's all. The problem is that there is no warning sign to this day. You should know that the design is dangerous, otherwise you will be saved by a lifeguard just like me (at least now there always is one). The design simply is bad and really maybe I should have sued them, but I forgot to mention that I was a small kid when this happened. I thought I simply wasn't a good swimmer. After I grew up I understood it wasn't my fault. I heard that the park actually got sued for this attraction by someone else. That's why now there is always a lifeguard. This is the only dangerous attraction. Everything else is safe. I think that when it was designed, people thought, that no one will fall of the boats. But I did. I survived and didn't sue them. I also didn't tell my parents until the next time we visited the park, which was over a year later. People regularly still fall off the boats. Most of them don't get caught in the machine and simply forget. The few that do are saved immediately now and there is no danger NOW. Before there was. I'd also like to mention that this is by far the SAFEST aquapark in Bulgaria I've been to. I had it easy, because this year my brother actually broke his foot in a different aquapark. The aquapark has already been sued multiple times for being too unsafe (mostly people who broke a bone). My brother fully recovered and is ok, and now you Americans know how bad safety is in most aquaparks here in Bulgaria. Now please let my fingers rest. Bad design! That's it. The designers forget the human factor. Also I would say, that when my brother broke his foot, it was mostly his fault. He was being reckless. That's why we (me and my brother) didn't sue them. Still safety in this aquapark is a low priority. All I say is that my brother is the only one responsible, for breaking his foot. Ok I am done. Please don't ask me any questions!
Edit 5: I have Covid now.
Edit 6: I have recovered (not fully, because I cannot smell or taste anything).

Who? Asked
Just Jeff For sure. Sucks the lead guy passed.
@Just Jeff Agreed.
Where I come from we call the "Drowning Machine" an undertow. I used to fish on a dam at Bernadotte IL like he mentioned. If you entered the river about 25 meters down stream from the damn and started wading towards it you would eventually start to feel the water pull you up stream, that's when you know to stop. There's been times I've seen logs and other debris roll around in the "dead zone" for a couple weeks before the river lowered (slower current) or raised (faster current) that would send it down stream.
They are no joke. Word of advice, if you see a bulge in river water and the surface is roiling, avoid it. It could be an undertow.
Side note, the Dam at Bernadotte was constructed for a WW2 camp called Camp Ellis for training and a POW facility. Interesting history if you're in to it.
Those are separate things. The drowning machine is the weir itself and the tumbling water at the bottom. The undertow is the undertow- an underwater current that travels "backwards" from the waves or current on top. If you ever swim in the ocean, you'll feel it if you're near shore every time a wave breaks and then pulls back though unless it's really rough and waves are large, it generally isn't strong enough to bother you or be dangerous.
@@mommy2libras Wrong, the undertow in the Greats Lakes, (specifically Lake Michigan) has killed plenty of people.
@@Project2457official Wrong. Undertows don't kill people specifically. They are dangerous because people caught in them don't know what to do, panic and drown. Or they try to swim against it and tire out and drown. But the actual drowning part isn't caused by the undertow itself. Undertows are also easy to get out of as they are small. They are also temporary.

There is one of these after the “falls” at my grandpas. It was fun to get pinned underneath because I liked practicing my breath holds. I only had the confidence to do so because getting out is as easy as hugging the bottom. I understand how dangerous it can be to someone uneducated or in a panic. Kind of disturbing that I used to do this unsupervised as a kid though
As I assume anyone watching Kyle Hill has probably heard of multiverse theory, I'd like to say that there are probably many, many parallel universes where you died in a drowning machine.

Yea, I havenever seen a "drowning machine" sign in the US near a dam or high water road crossing/spillway warning, Just danger signs , risk of drowning, do not swim, etc. Key thing is don't swim or raft near a dam or go into a flowing spillway.
@@chrisperrien7055 Portage..... is the word .....
The local river here has plenty of dangerous low water dams, but I've never heard them called drowning machines or seen signs like that. In fact, there are no warning signs at all.
@@chrisperrien7055 I remember a guy once drowned trying to kayak over one here.
Yeah even downstream of Cumberland dam, the sign only says "Dangerous Currents. No swimming"
I haven't been stuck in a Drowning Machine, but I've done the surfer's almost-equivalent: wiping out with really poor timing on the first wave of a big set and having the next three breakers land on your head one after the other. One of those moments where you seriously feel like there maybe aren't going to be any more moments.
I love swimming, but there is nothing worse than bad timing a set of waves. Whenever they say calm heads prevail, I think of the times I have come up for air only to meet resistance or more water. You just have to rally, time it, and find it. Nothing like the rush of another chance.
dude this exact thing happened to me i felt my body contort to the wave and i really couldn’t get out, i relaxed a bit and let the waves wash me up on the beach, what was like 30-40 seconds felt like my life flashing before my eyes
I heard from a diver for the core of engineers if you’re ever caught in that turbulence swim strain towards the bottom as far as you can go then strait out
Similar idea to swimmers caught in whirlpools. Swim with the spin as fast as you can for two revolutions - even though you're being sucked down - so you can use more momentum when you try to burst outward.
Although, of course, it's better to recognize and avoid a whirlpool before you get sucked too close.
That's correct! The water flowing out of the drowing machine is at the bottom, the water flowing in is at the top! So the only way to get out is to get to the bottom and then swim as hard as you can along it.
There were several of these dam on the small river in my town that were used to power/run the various old mills, however since the mills had all been closed for decades, while I was in highschool it was decided to remove them after a large spike of deaths occurred over 2-3 years including 3 of my classmates. They are incredibly deceptive too as the one here that claimed the most lives could just barely be seen if you looked at it head on when going up stream but if you were going down stream then it's be invisible until you were right on top of it at which point you'd get sucked in and stay there.
This is exactly the situation surrounding the one in my area. Minus the "let's tear it down" part
@@DeathSabr3 I don't understand that in today's day and age, where 'safety' is such a buzzword thing, they wouldn't make these dams safe.
I mean, it's not like it's fucking rocket science or anything to just design a dam that either doesn't have a drowning machine or has safety mechanisms that prevent you from getting stuck in one...
It does probably cost a bit more money though.. which just goes to show you how much a human life is áctually worth. :)
@@ayporos oh I agree. The community i live in is much more invested in putting every last tax dollar into their football programs and bibles rather than listening to a scientist or think of other people's safety
@@ayporos Perhaps put a fence in the water or a net that just makes it impossible for people to cross the threshold without noticing. I dunno at least that sounds like a cheap easy to do fix for that situation but I'm no engineer.
@@Despoina_Nyx I doubt that'd work. People would get stuck on the net and also logs and other trash floating in the river would fuck that net up.
There's actually one of those low dams at a nearby river where I live. It's completely unmarked though because it's incredibly shallow, and you can stand in where the actual vortex is just fine. I actually got caught it it briefly once as a toddler because I was itty bitty, but my parents were always watching when we were next to it. Interesting how if the water was a bit deeper, I could have easily died. One of my common play places as a child.

The scary part is if you get cought in something like this, you have to go against your intuition and try to go deeper into the water which actually forces you away from the dam. Any attempts of going up meets you with reverse current which again pushes you back to the dam and the vortex

I had been over it 4 times before going straight that’s why I went backwards but my uncle who brought me on it said he once went over it without a life jacket and almost drowned so he uses life jackets when he goes on rivers now.

@@grahamfisher5436 Damn, and I thought I was having a bad day. Sorry mate.
So there are a few rescue techniques that we learn in kayaking for getting people out of “holes” (whitewater terminology for one of these types of hydraulics). Most of them involve reaching in with a solid object (paddle, typically) to try and give them something to grab if you can get close without entering the water yourself. Throw ropes aren’t recommended because they will circulate around the victim and potentially tangle them up with something under the water and make things worse.
The best one (by sheer coolness factor), though, is a last-ditch rescue called a “live bait” rescue. By attaching a rope to the back of a rescue pfd (which has a quick release loop for such things) a rescuer can jump into the hydraulic, grab the victim, and then get pulled out by friends on shore. This is risky, for the same reason that throw ropes are, but allows you to keep the rope more taught and is easier to get the victim attached (especially if they’re disoriented and/or unconscious). I don’t recommend anyone without training try this, as it is risky for sure, but it is a cool thing to know about.

Kyle: "I'm not a super villain!"
Also Kyle:
I guess I'm one of the only survivors of a drowning machine!! When I was around 18 I was taking a walk on a bike path by a river in Fort Collins, Colorado. I decided to take a swim in a part of the river that was upwards of a small damn which had 2 divots (the drowning machines) on either side of a small ramp that the water flowed down. The water that I was swimming in was very slow, so I wasn't that worried about getting caught up in the stream. Well, then there goes my dumb but, just lazily floating on my back for fun, I feel like I'm picking up speed. I had floated down stream to one of the divots, where I could see that the water rushing over the edge looked very violent. Unfortunately for me I was to late to swim out of the current and I had lodged myself into the divot. With only my arms holding me against the damn, the water pressure was trying to push me over the edge, I remember the water rushing over my body and head, making a small space of air where I could still breathe without drowning. I could lift up my head but the water pressure kept me from breaching the surface for long, luckily I was able to yell for help and some other people out on walks heard me, and tried to help. They couldn't really help ofcourse, so I had to let go of the damn and let the water push me over the edge. Lucky for me that the drop was only 4/5 feet deep, and I could easily stand in the shallow hole. I swam out and have been mentally scarred since.
Edit: I don't remember if they had the sign out there though

There is also another one you could make a video about.
My father worked at wastewater plants for 30 years.
The aerator tank. It's one that holds about as much water as two or three typical swimming pools, with many tanks beside eachother... same size over. (Greatly depends on plant size. He worked at a 5MG per day plant)
They have huge air pumps with pipes under mounted on the bottom, they are designed to separate solids from the waste so the "sludge" can be pumped out and processed later.
When the aerators are on its pretty wicked looking. The way it rolls the water. My dad used to do demonstrations for videos dropping a basketball in a simulated tank. It will sink to the bottom immediately.
As would a human. You cannot swim in a aerated tank.
All the airbubbles create dead space and you sink like an anchor.
I used to go onto the catwalk all the time to see it working.
Another fun fact. My dad designed the most commonly used programing at SBR wastewater plants used today. And also developed one of the best aerator systems and was close friends with one of the developing fathers of the SBR plants creation.
In fact. My middle name was named after him.
He wrote many books back in the 60s and 70s developing it. As well as studying the types of bacteria to insert to "digest" the poop

@@CEbbinghaus what level of aeration is it?

It's like saying heat melts steel. What steel and what level of heat?
The aerated tanks have to work at SBR plants. That's what makes poop and other solids SINK, so it can get sent to a digester or belt system to remove it. Otherwise it all floats.
