i hate to get technical, but, scuba is Self-Contained Underwater Breathing Apparatus. what he is using is a Surface Supplied Breathing Apparatus. nice effort tho
Very scary part is the hand air pump. Typically there is a thin film of oil that helps seal the piston to the wall of the cylinder and THAT becomes extremely poisonous when breathed in, especially under pressure.
My grandfather built a diving helmet in the fifties out of metal (Not sure what kind) so its heavy enough to weigh you down. It also uses a bicycle pump with a long cable to supply air. Really cool I’ve messed around with it in a pool a few times. He used to use it to explore ponds and lakes with it. Sounds kinda creepy to me.
To fix the CO2 problem, get a rubber tube that is long enough to connect from your mouth to the side of the helmet. This way, you can breath the fresh air with your nose and exhale the CO2 with your mouth. Keep in mind you must tape the end of the tube to the helmet so it doesn't float around you. (To keep it stabilized) Also, I recommend adding a mouthpiece to the front of the tube to make it more comfortable. :)
Hi everyone! Thanks for watching this vid. I see there's people wondering about the science behind the Scuba helmet. Honestly - I don't know how it works! I took a risk and I figured that I wasn't going to be underwater for a long time and I also had a very qualified diver filming me and watching out for me. I looked into how the helmet would work and the explanation I give in the video is how I interpreted it. To be honest I didn't think this video would reach this many people. However, I am planning on building a bigger, better diving bell next year and I WILL make sure I get the science right! I'm sure one of you guys knows the correct way the scuba helmet works and I'd love to know, too! So keep commenting below and subscribe to keep updated. Thanks everyone
+TREADER TUBE Ya know, you really, really ought to go to a local dive shop and have them give you a short tutorial on the physics of diving. It's really pretty simple and you can get some info that might actually keep you from killing yourself. For example, air from a tire pump is NOT usually poisonous as someone suggested, but it's lubricated with oil and tiny particles of oil can get into the air and then into your lungs. If you get enough, your lungs cease to work and you suffocate. You probably did some damage with this one dive but obviously nothing serious but you'll never be able to fix what you've done and if you keep doing it, the affect is cumulative. And that's also why most diving air compressors are electric because there's no exhaust gas to be picked up and compressed with the air going into your lungs.The sad part about all this is that you're risking your life because you don't have a clue about what you're doing and the information is right around the corner and readily available in books.Experimentation is great. That's how man has made so much progress over the years. People have died trying to gain knowledge about such things as diving. But, that occurs to serious experimenters when the body of knowledge is sparse. In this case, it's not sparse and you're not going where no man has gone before. It can be incredibly dangerous even in shallow water if you don't know what you're doing.Please, don't hold your breath while you return to the surface. It can kill you in just a few feet. Your dive shop can tell you why,
+I'm Grateful Thanks for posting a structured comment. Totally appreciate your points made. As I wrote above I never thought this video would reach as many people as it has but a lot of the comments have helped me realise that this was more dangerous than I thought. However, one of the craziest things was trying to get the right information in the first place. People weren't too forthcoming when I said I wanted to make a scuba diving helmet out of a plastic bottle. I understand it's stupid and they thought I was an idiot but without any learned guidance I had to muddle through the best I could. I like how you mentioned that 'mankind makes progress by experimentation', and despite me not recommending anyone copies this, I do believe in trying things yourself - even if they've been done before. Anyway, despite the stupidness it was a project built on fun. I've got less-dangerous vids on my channel. Thanks again
I know this Steven Henderson But I dont have the money for it.... im broke, but ive got an empty water bottle an a hose pipe :-D I will catch the lobsters to buy scuba gear then... then I will catch shit loads of them lobsters and scollops... i'll be making all kinds of fish money ;-) Thanks TREADER TUBE
+ Chris Elliott -- There's no need for that if a better pump is used. The fresh air coming in from the pump will displace the CO2 in the helmet if the flow volume is high enough, just as it has been doing for hard hat divers for more than 180 years. The problem here was that the hose got kinked in several places and so the fresh air flow was restricted. (And the bicycle pump probably was not providing enough air to begin with. The deeper you go the more air it takes to fill your lungs, so a bigger pump is needed to be actually usable for any extended period.)
Hi Johnny, definitely agreed - no one should do this alone - or without support. The video doesn't really show it but we had a pony bottle with regulator down there, Rob (the diver) was there with me the whole time and we weren't in deep water or in an isolated location. We had a lot of fun and this video got a lot more attention than I ever thought! Thanks for you comment
I saw the pony bottle at the bottom and the divers with you. The biggest problem would have been not staying straight up and the jug filling with water if put on it's side.
I am a commercial diver as well. As you know the deeper you go the pressure increases. At 1ATA 33' the pressure double and volume of air iinside the hat would decrease and it would get to the point where it would cover your face. To over come this would require more weight and a lot more air. So this would only work in shallow water and the likelihood of in major trouble would be negligible. I can think of a few ways to over come this but then it could get you in some trouble.
+THE UNKNOWN there could be a possible way to avoid that. If there was a substantial supply of oxygen entering the helmet to balance the loss of pressure from the co2, it could possibly work. However, I haven't taken physics so don't quote me on it

If your air source is on top pushing downward and carbon dioxide is heavier than o2, the excess gas should 'spill' out of the bottom of the bottle once it gets too full. So as long as your friend is pumping more fresh air than the amount of carbon dioxide you are producing you should be fine
Now you know why the old hardhat diving helmets were big heavy brass and glass contraptions. Add about 8lbs of weight to the lower edge to achieve a more neutral bouyancy. Might take moreweight than that, but start out light. And you will want some weight at waist level or below. You want to naturally float vertical or nearly so, head upward of course, with any open helmet type system, so you don't spill your air. Releasing too much air by leaning the helmet will instantly send you toward the bottom until you recover your bouyancy control. Some of the weight should be held on by some sort of releasable mechanism. You should always be able to dump some or all of your weight. Also it would be helpful if you could build some sort of BCD, or bouyancy control device. This is a vest type afair that is inflatable from your air supply and has purge valves at all possible high points to release excess air. Add air to increase bouyancy. Release air to sink. When it is right on the money you can maintain your depth by controlling the amount of air held in your lungs. As you sink you will sink faster and faster. As you rise you will rise faster and faster. This is due to the change in your bouyancy with change in pressure. Reducing the volume of your helmet will improve performance. At least partially enclosing the bottom will help prevent air spillage, too. There is no reason why you could not homebrew a full 1920's style dive suit and helmet, actually. Since it would not be acceptable as a serious diving outfit, you would of course confine yourself to very shallow depths such as the depth you tested your water cooler bottle helmet in. It would be a fun and educational project. Just be sure you don't get the ultimate lesson, and get bent or dead. Even with real professional equipment, brass hat diving was a very hazardous undertaking. Also there are lots of DIY plans and instructions out there for rolling your own hookah compressor, some of which will kill you and some of which might not. Might be better than a buddy on a bicycle pump. And you need some filtration in your system. You might not think so, but you do. If you save your nickels long enough, you could get SCUBA certified and learn a lot about diving that might save your life some day. Plus you would learn about more practical equipment, and be able to get tanks filled, and go on organized dive trips. Real diving can be a lot of fun as well as useful and even lucrative enough to pay for your gear. There's an awful lot of boats out there that need their bottoms cleaned, and zincs that need replacing, and important stuff dropped overboard in harbors. I tried something similar to this when I was 10yo. I am lucky to be alive to admit it. Just sayin. I won't even build my own tank fill compressor or even hookah compressor. Only commercially available SCUBA gear for me, thank you.
You cant just breath with the hose floating above u sucking in the air without it being force fed into u ? I have a gas cylinder like you see at a store for the fountain drinks . I would like to buy the scuba mask and air dial knobs to convert it into shallow water dive. I have a popular swimming hole here in TX. I put on a headlight and goggles swam down to bottom about 10 ft. Or more and I saw a light shining at the bottom , I was able to go STRAIT at it . Ended up being a silver ring with a TX Star and 15 little diamonds. Now I want to be able to go down and look longer and start doing this after each summer break
Well done ! Unaware of 2000+ years of diving history, & thus uninformed by the developments in underwater breathing technology, you have reinvented the wheel.You have re-discovered the surface supply free-flow helmet. Versions of the hat have been around for hundreds of years,but they all required considerable engineering.Your hat is fantastic. You've made it very cheap & easy for anyone to take a look underwater. I see you have already noted the many warnings you received as to the many dangers you were exposed to.I hope your viewers do likewise. Commercial divers today use a development of this idea, with several safety features added to it. with your open bottomed design, you rely totally on your buddy pumping air down to you to provide the pressure to keep the water out of the hat. If he has a heart attack,you get no more air.When you breathe in,you will notice the level of water in the hat rise. When you breathe out, it will sink again.Each time you breathe in, you convert 4% of the oxygen in your body to CO2. After a couple of breaths your hat will be full of CO2 & you will pass out & die. If, on the other hand, your supply hose bursts, or comes off the pump, the hat will lose all it's air, & all it's pressure.The water at the base of the hat is being pushed down by air pressure, when that goes the water fills the hat.In seconds.So you drown. So you see the need for improvement that led to modern diving helmet technology. We add a neoprene neck dam which seals around the neck & connects around the bottom of the helmet.This stops the water coming in if you lean over. We add a non-return valve where the air comes into the hat.This prevents the air in the hat from leaking out if the supply hose comes loose or is cut. We also carry a spare air supply on our backs. Apart from that, we use your hat. Nowadays, the attention is on the air supply.Best Diving Industry Practice requires at least two independent air supplies, each capable of allowing the diver to reach a place of safety. For us, this means 2 big compressors or 2 sets of bottled air.Your system will need a better air supply. Your equipment is thus very primitive & out of date, but at the same time delightfully new. I would love to see you develop this gear. Used in benign conditions, with a little bit of guidance, you could have lots of fun. If any of my above situations occur where you are likely to use this gear, in shallow open water, you just drop your weights & come up . Your one remaining hazard is CO2 poisoning. If there is not enough flow to flush it all out of the hat, it will build up. CO2 is dangerous.It dulls your thinking & makes you clumsy.Enough can kill you.Symptoms are feeling hot, feeling anxiety, & most identifiable, rapid shallow breathing.A throbbing headache for hours after a dive suggests CO2 poisoning.I would eliminate the possibility by fitting a DV mouthpiece to your hat allowing you to blow each breath out of the hat. Your air line was kinked (visible in the video).This will cut off your air supply. We (Commercial divers) must use airline rated to 30 bar & 500kg breaking strain.You may use whatever you like. I would use the largest diameter hose pipe I could find - the entire pipe will act as an air storage device & give you a couple of breaths. Thanks for the video, I will make one of these.
Thanks for the detailed comment, lots of info! I didn't expect the video to been seen so much and I was just having some fun, I wasn't even sure if it'd work. I do wish I could go back and do it again and sort the things I chose to overlook (kink in hose etc). I know people have gotten annoyed about the vid but that's what happens when 1 million + people see something. Can't please everyone. I actually went and dived an old sunken Soviet prison - check it out: ua-cam.com/video/8bm9O1OoHII/v-deo.html
I did almost exactly this but with a bucket and lead weights in my parents pool. Worked fantastically until the air hose blew off the pump, almost immediately sucking all the air to the surface. Luckily I just ducked out and stood up.
You need to add a one way valve, a very important safety feature on all dive helmets. Myth-busters did an episode on this ua-cam.com/video/LEY3fN4N3D8/v-deo.html
For the Co2 problem just have a tube for your mouth to the underside of the jug. You going breath in through your nose and breath out through your mouth
In the first minute you said "I will be creating co2, and I'm afraid that will make the oxygen come out of the bottom". You even made a animation for it. Well the problem with that idea is as you breathe your lungs use the oxygen, and turn it into co2. It is an equal exchange. You are creating no additional material, you are only using all of the oxygen in your helmet. Furthermore, you have additional air being pumped into your helmet, but no where for this additional air to go. Which then causes the problem you just got done mentioning "air coming out of the bottom". Smooth.
in the early days of scuba there were no scuba shops only mags that explain how to make your own scuba gear and called it a water lung. most parts needed were from military depo's, like old airplane parts. now we are so unlearned using our own hands we cut open waterdispencer tanks and call it a scuba helmet
Improvise a type of snorkeling tube for your mouth to run under your diving bell, in through nose, out through mouth c02 problem solved. For the design make sure there are plenty of counter bends to make sure water doesn't flow into your mouth inadvertently, and stabile for multiple angles
Physics my friend. Take a cup, put it upside down, push it into the water. The water creates a seal on the bottom of the container preventing the air from escaping. As soon as he turns sideways the seal is broke and the water will float up. It's kinda hard to explain. The container keeps air from passing through it and the air is lighter than the water so it can only go up. It can't go down to escape the container.
+Carrie Marsyla not if you pressurize the "hose" correctly. I personally wouldn't use a hose. Only so much air can escape if you create a small exit at the topside end of the hose. The most difficult task is finding out just how big or small the exit has to be.
sorry if this has already been said, but its not a "scuba helmet" as it is not self contained it has a supply from the surface, scuba means self contained underwater breathing apparatus
just got an idea, so, if you put an opening with a tube going to your mouth, you be able to exhale out the mouth, and inhale with your nose, now water getting into the tube can be fix, probably, (I'm not genius so), just put a spring loaded flap on the front, so that when you exhale, it pushes the flap, and when your done exhaling, it closes because of the spring. :)
to fix the problem of carbon dioxide, you should add a little hose that is connected to the bottle, going inside, with something that prevents water from getting in. of use a snorkel instead of a hose
That was brilliant, just 2 comments: coat the internal wall with abit of edible oil to dispel the fog, and if you don't want the mix of CO2 in the tank, have a pipe to breathe out of.
Denser liquids go down and less dense liquids go up. With the CO2 molecule being heavier than the O2, it would make it go down and not up as you suggested. The close enclosure and constant flow coming from the pump and your breathing would mix the gases, so there would not be a clear "gas A" would be pushed down and "gas B" remains on top. Taking into consideration that humans only absorb about 4-5% of the oxygen contained in one breath and the constant pumping of air, your "light headedness" was probably psychological. This could be easily tested with an O2 measurement device.
+ Ryan Bowden -- Commercial divers have been using -- and still often use -- surface-supplied air from compressors for more than 180 years. And the air in your scuba tanks comes from compressors as well. You just have to use the right kind of compressor.
I have a idea I do t know if you will see this or still ha e the helmet but you should drill a hole in the side and put a snorkel I. It leading out into the water so when you breath out you breath out through the tube so their is less co2 in the helmet
Why not have another tube. The one with oxygen from the pump at the bottom and the one taking air out to the surface. If co2 will rize to the top it should get pushed out through the top tube
I'd love to give it a try. My friend has done some and she said it was amazing. But she moved back to London and practiced in the bath but she said it 'just wasn't the same'. I believe any type of breath control training has a lot benefits
Great try!! Can't figure out how you sealed it at the neck, or where your CO2 went? But you're going to invent something fantastic. Keep inventing "DaVinci"
0:34 Problem fixed by having another tube that goes from your mouth under the rim. You brethe the good air in threw your nose and you exhale into the exit tube which bubbles the carbon dioxide out to the surface. Using your nose and mouth like a simple valve. :) Of course you could just breathe threw a tube.. in threw your mouth and out threw your nose.. But hey.. The snuba helmet looks really cool. :)
The carbon dioxide is heavier so that will get pushed out of the helmet as he pumps air into the helmet before the air gets pushed out so that isn't a problem
Hi. anyone can tell me where i can buy underwater helmet or unerwater scooter? i am over three mounth searching where to buy on or another kind of under water brething helmets
You could have a tube that goes under the helmet to exhale into. So you have the tube in your mouth, you breath in through the nose and breath out through the tube. Would solve the co2-problem cheaply.
Two things one because co2 is heavier it will sink to the bottom of the container and be pushed out so that’s not a problem However this is dangerous as impurities in the pump such as oil and rubbed off bits of metal will be breathed in causing lung damage
you should drill holes in the side for your ears so you can hear the fish laughing their asses off
But you won't hear them because you already drowned.
*the whole point*
+Waddle Dee u could when u get nitrogen narcosis :d
I was gonna say that
where does this fantastic humorous sarcasm come from?! You should be making money out of it :D srsly

It's all fun and games until he turns sideways
ikr lmao
NoAvailabeUsernames why? What would happen if he turned sideways?
Mark burns dip an empty water glass into water upside down. If it's strait no water gets in, turn it sideways and it fills right up
I don't know? At least he is not alone.
He could take it off and surface
North Korea's space program could use your test data.
he meant it as a joke
Haha awesome comment. What if I was actually using their plans for when building my helmet - would make equal sense :)
My grandfather built a diving helmet in the fifties out of metal (Not sure what kind) so its heavy enough to weigh you down. It also uses a bicycle pump with a long cable to supply air. Really cool I’ve messed around with it in a pool a few times. He used to use it to explore ponds and lakes with it. Sounds kinda creepy to me.
So would it work with a air mattress electric pump? It would supply constant air without having someone pump
Good question!
It would rip your head off as you try to submerge
why
I don't think it would have enough pressure to get into the helmet
It would not work because your lungs would explode
You are the first guy on earth who try to dive with plastic bottle, respect!!
Nah, he's just the first guy to tell anybody about it.
says "CO2 is heavier than air" then shows a diagram of CO2 being lighter than air
Antonio .Botic 😂😂😂😂
looks like a nice stream , lots of flowing clean water and deep.
I built one a while ago, to prevent co2 from building up i breathed out using a tube that went outside the helmet thing.
If the co2 is heavier then the air why shouldn't I float on the bottom of the bottle and been pushed out by the pump???
Office Manager: "Hey, has anybody seen the water bottle?"

You could seat the snorket outside of the helm, and keep it (the mouth piece) in your mouth. no contact to the air in the helmet, no problem.
If your air source is on top pushing downward and carbon dioxide is heavier than o2, the excess gas should 'spill' out of the bottom of the bottle once it gets too full. So as long as your friend is pumping more fresh air than the amount of carbon dioxide you are producing you should be fine
You should make an air compressor buoy that you drag around as you swim/walk.
That would be super cool
TREADER TUBE Especially since you just need foam to keep it afloat and batteries to keep it running as you have the hose already.
1:48 the tube wasn't even connected?
This is cool. My grandfather made basically the same thing years ago, but it's made out of metal.

ok Thank you! :-)
One thing you could do is have a 2 vale system that has a ball in it that relesise co2 but dos not let water in
+The angel Of dream that is a great idea!
use an electronic air pump for mattresses so u can go to beach and have more air
Why dont u use a tube to exhale CO2? so it wont mix with the O2
You cant just breath with the hose floating above u sucking in the air without it being force fed into u ? I have a gas cylinder like you see at a store for the fountain drinks . I would like to buy the scuba mask and air dial knobs to convert it into shallow water dive. I have a popular swimming hole here in TX. I put on a headlight and goggles swam down to bottom about 10 ft. Or more and I saw a light shining at the bottom , I was able to go STRAIT at it . Ended up being a silver ring with a TX Star and 15 little diamonds. Now I want to be able to go down and look longer and start doing this after each summer break
Well done !
Unaware of 2000+ years of diving history, & thus uninformed by the developments in underwater breathing technology, you have reinvented the wheel.You have re-discovered the surface supply free-flow helmet. Versions of the hat have been around for hundreds of years,but they all required considerable engineering.Your hat is fantastic. You've made it very cheap & easy for anyone to take a look underwater.
I see you have already noted the many warnings you received as to the many dangers you were exposed to.I hope your viewers do likewise.
Commercial divers today use a development of this idea, with several safety features added to it.
with your open bottomed design, you rely totally on your buddy pumping air down to you to provide the pressure to keep the water out of the hat. If he has a heart attack,you get no more air.When you breathe in,you will notice the level of water in the hat rise. When you breathe out, it will sink again.Each time you breathe in, you convert 4% of the oxygen in your body to CO2. After a couple of breaths your hat will be full of CO2 & you will pass out & die.
If, on the other hand, your supply hose bursts, or comes off the pump, the hat will lose all it's air, & all it's pressure.The water at the base of the hat is being pushed down by air pressure, when that goes the water fills the hat.In seconds.So you drown.
So you see the need for improvement that led to modern diving helmet technology.
We add a neoprene neck dam which seals around the neck & connects around the bottom of the helmet.This stops the water coming in if you lean over.
We add a non-return valve where the air comes into the hat.This prevents the air in the hat from leaking out if the supply hose comes loose or is cut. We also carry a spare air supply on our backs. Apart from that, we use your hat.
Nowadays, the attention is on the air supply.Best Diving Industry Practice requires at least two independent air supplies, each capable of allowing the diver to reach a place of safety.
For us, this means 2 big compressors or 2 sets of bottled air.Your system will need a better air supply.
Your equipment is thus very primitive & out of date, but at the same time delightfully new.
I would love to see you develop this gear.
Used in benign conditions, with a little bit of guidance, you could have lots of fun.
If any of my above situations occur where you are likely to use this gear, in shallow open water, you just drop your weights & come up
. Your one remaining hazard is CO2 poisoning. If there is not enough flow to flush it all out of the hat, it will build up. CO2 is dangerous.It dulls your thinking & makes you clumsy.Enough can kill you.Symptoms are feeling hot, feeling anxiety, & most identifiable, rapid shallow breathing.A throbbing headache for hours after a dive suggests CO2 poisoning.I would eliminate the possibility by fitting a DV mouthpiece to your hat allowing you to blow each breath out of the hat.
Your air line was kinked (visible in the video).This will cut off your air supply.
We (Commercial divers) must use airline rated to 30 bar & 500kg breaking strain.You may use whatever you like. I would use the largest diameter hose pipe I could find - the entire pipe will act as an air storage device & give you a couple of breaths.
Thanks for the video, I will make one of these.
Thanks for the detailed comment, lots of info! I didn't expect the video to been seen so much and I was just having some fun, I wasn't even sure if it'd work. I do wish I could go back and do it again and sort the things I chose to overlook (kink in hose etc). I know people have gotten annoyed about the vid but that's what happens when 1 million + people see something. Can't please everyone. I actually went and dived an old sunken Soviet prison - check it out: ua-cam.com/video/8bm9O1OoHII/v-deo.html
whit a small mod you can get read of CO2 just adding a pipe where you can
breathe out in tho the wather
You couldn't bring one of those inflatable sofa inflating pumps?
What part of the lakes were you in?
Hi Silas, we were down in Grasmere.
ahh good ol grasmere
Don't you need a tube for the co2 to go out of?
someone tells me how is water can not be put under the hole of the Caneca
Anyone know where I can book a trip with this genius?
You said CO2 is more dense than air so why would the dry air not push the co2 out the bottom
I did almost exactly this but with a bucket and lead weights in my parents pool. Worked fantastically until the air hose blew off the pump, almost immediately sucking all the air to the surface. Luckily I just ducked out and stood up.
Haha! What a nightmare! Good effort though :)
I almost garentee you started shaking.
^ that spelling though
You need to add a one way valve, a very important safety feature on all dive helmets. Myth-busters did an episode on this ua-cam.com/video/LEY3fN4N3D8/v-deo.html
if carbon dioxide is heavier than air, shouldn't it float down instead of up? which causes the carbon dioxide to be pumped out????
For the Co2 problem just have a tube for your mouth to the underside of the jug. You going breath in through your nose and breath out through your mouth
get a contractor garden hose to keep it from kinking on you. Awesome video!
+John Garet thanks for the advice, John. And thanks for watching 😎👊🏼
In the first minute you said "I will be creating co2, and I'm afraid that will make the oxygen come out of the bottom". You even made a animation for it. Well the problem with that idea is as you breathe your lungs use the oxygen, and turn it into co2. It is an equal exchange. You are creating no additional material, you are only using all of the oxygen in your helmet. Furthermore, you have additional air being pumped into your helmet, but no where for this additional air to go. Which then causes the problem you just got done mentioning "air coming out of the bottom". Smooth.
fun idea but why a bike pump? why not a air bed pump? it makes greater airflow then a bike pump
or an o2 tank
or a scuba set
in the early days of scuba there were no scuba shops only mags that explain how to make your own scuba gear and called it a water lung. most parts needed were from military depo's, like old airplane parts. now we are so unlearned using our own hands we cut open waterdispencer tanks and call it a scuba helmet
back in the day when we were kids, we just evolved back into fish.
okay
What kind of bike pump did you use cuz I need it.
so what would happen if he tilted over
I'd have to drink a lot of water pretty quickly!
Dose the bycile pump give enogh air
Improvise a type of snorkeling tube for your mouth to run under your diving bell, in through nose, out through mouth c02 problem solved. For the design make sure there are plenty of counter bends to make sure water doesn't flow into your mouth inadvertently, and stabile for multiple angles
should try a leafblower not a bike pump it keep the air fresh
Sick idea!
how is there no water flowing INTO the bottle? It's not sealed around his neck?
Physics my friend. Take a cup, put it upside down, push it into the water. The water creates a seal on the bottom of the container preventing the air from escaping. As soon as he turns sideways the seal is broke and the water will float up. It's kinda hard to explain. The container keeps air from passing through it and the air is lighter than the water so it can only go up. It can't go down to escape the container.
is this a diving bell?
you mus make an extra hose to the serfese for draining the co2
An open hose to the surface would supply air to rapidly escape forcing water up into the helmet
+Carrie Marsyla not if you pressurize the "hose" correctly. I personally wouldn't use a hose. Only so much air can escape if you create a small exit at the topside end of the hose. The most difficult task is finding out just how big or small the exit has to be.
wait... if CO2 is heavier than air, would'nt it sink to the bottom?
sorry if this has already been said, but its not a "scuba helmet" as it is not self contained it has a supply from the surface, scuba means self contained underwater breathing apparatus
From mad lam?
use a snorkle when you exhale , it will prevent most of the oxides out of the helmet while you're pumping fresh air in
can you try to go into space with this?
Great idea! Imma need a space ship.... next build video perhaps?!?
just got an idea, so, if you put an opening with a tube going to your mouth, you be able to exhale out the mouth, and inhale with your nose, now water getting into the tube can be fix, probably, (I'm not genius so), just put a spring loaded flap on the front, so that when you exhale, it pushes the flap, and when your done exhaling, it closes because of the spring. :)
That sounds pretty logical. I'll put it in the plans for scuba helmet #2
TREADER TUBE cool
I think hose is not conected to pump on 1:45
to fix the problem of carbon dioxide, you should add a little hose that is connected to the bottle, going inside, with something that prevents water from getting in. of use a snorkel instead of a hose
That was brilliant, just 2 comments: coat the internal wall with abit of edible oil to dispel the fog, and if you don't want the mix of CO2 in the tank, have a pipe to breathe out of.
+Lawrence Ho Thanks! That sounds like a great idea
+TREADER TUBE Just make sure the edible oil wont hurt ya lungs. If possible use legit non-toxic defog used in diving. Then no die xD
Denser liquids go down and less dense liquids go up. With the CO2 molecule being heavier than the O2, it would make it go down and not up as you suggested. The close enclosure and constant flow coming from the pump and your breathing would mix the gases, so there would not be a clear "gas A" would be pushed down and "gas B" remains on top.
Taking into consideration that humans only absorb about 4-5% of the oxygen contained in one breath and the constant pumping of air, your "light headedness" was probably psychological. This could be easily tested with an O2 measurement device.
okay good I'm glad I'm not the only one
hope at top with tube going out of water to release co2
You should hook up an air compressor so you don't have to pump the air in
Good idea!
That's good you're Scuba certified Ryan. But you obviously know fuckall abut surface supplied.......
+ Ryan Bowden -- Commercial divers have been using -- and still often use -- surface-supplied air from compressors for more than 180 years. And the air in your scuba tanks comes from compressors as well. You just have to use the right kind of compressor.
TREADER TUBE no it’s not don’t do that as they are very dirty and the oil could cause a blackout
Did any one else think he looked like a LEGO figure?
+Clifford Moeller 😂
Why didn't you integrate a snorkel and breath out the co2 with that and breath in o2 with your nose
it kinda works, need a better air pump to force the co2 out and some weight to the helmet.
What does snuba even stand for?
"Can you see the Air coming out?" LMAO
Hi there, where abouts is this??
Couldn't you just hook 2 Electric pumps 1 faster than the other that way their would be oxygen and co2 exchanged?
you should use a small air compresser
I have a idea I do t know if you will see this or still ha e the helmet but you should drill a hole in the side and put a snorkel I. It leading out into the water so when you breath out you breath out through the tube so their is less co2 in the helmet
Nice shirt dude, great taste in music
Nice video, thumbs up from us and cheers from sunny IGY Simpson Bay Marina, Sint Maarten in the Caribbean.
Thanks! What a beautiful location :)
saint maarten, I got my dog from there at the I love my island dog association
where ankle weights and and a chain around ur waste with weights hanging off...pretty awesome
+ChArLiE BeAtZ good suggestion
+TREADER TUBE Thank You, you can also use an air pump, for less manual labor
+TREADER TUBE I wonder if u can rig an aquarium pump, to your apparatus
You can actually get a bucket and put it on your head and it's like a air pocket so you can breath you don't need a pump to pump air in
+Padric McGrath I've already done it before
And I didn't run out of air
+Tyson Morris you will if you're down there long enough. The bucket will fill up with co2
+Tyson Morris you wouldnt necesseraly know you're not breathing the right stuff until its too late.... You just didnt get to that point
where is this lake at???
how do you equalize on that?
Where was this
Why not have another tube. The one with oxygen from the pump at the bottom and the one taking air out to the surface. If co2 will rize to the top it should get pushed out through the top tube
Can you please make a video how you made the Scuba Diving Helmet plz!!!!!!!!
How does he clear his ears?
This is some next level sandy squirl
Where in the lakes are you. I'd like to meet you guys and go for a swim. I'm 15
Hey George, I don't live in the Lakes, I just visit often. I'll let you know when we're up there next
+TREADER TUBE thankyou
Do you ever freedive
I'd love to give it a try. My friend has done some and she said it was amazing. But she moved back to London and practiced in the bath but she said it 'just wasn't the same'. I believe any type of breath control training has a lot benefits
+TREADER TUBE Javea Spain is best for it. me my parents and my siblings all go there every year
Great try!! Can't figure out how you sealed it at the neck, or where your CO2 went? But you're going to invent something fantastic. Keep inventing "DaVinci"
+Marykat Sundahl It doesn't seal. And its hardly a new concept...
+r. decline didn't think concept was new; just appreciate anyone trying diys
0:34 Problem fixed by having another tube that goes from your mouth under the rim. You brethe the good air in threw your nose and you exhale into the exit tube which bubbles the carbon dioxide out to the surface. Using your nose and mouth like a simple valve. :)
Of course you could just breathe threw a tube.. in threw your mouth and out threw your nose.. But hey.. The snuba helmet looks really cool. :)
The carbon dioxide is heavier so that will get pushed out of the helmet as he pumps air into the helmet before the air gets pushed out so that isn't a problem
Hi. anyone can tell me where i can buy underwater helmet or unerwater scooter? i am over three mounth searching where to buy on or another kind of under water brething helmets
You could have a tube that goes under the helmet to exhale into. So you have the tube in your mouth, you breath in through the nose and breath out through the tube. Would solve the co2-problem cheaply.
bike pump sir isnt good for you either is compresor sir becarefull theres specisl airtanks for a reason
+Olivier Beaulieu How do you think they fill the airtank's up?
+GlennDHS They have compressors with special filters for air cleaning and water removal.
+Markus Birth (mbirth) yeah
lol i meant air not sir
You could use a snorkel to exahle. Then if you inhale with the nose and exhalr trough a snorkel , no carbodioxide would stay in you jelmet
You should have had an escape route for the Co2 out of the top of the bottle.
What if you got a plug in pump
Two things one because co2 is heavier it will sink to the bottom of the container and be pushed out so that’s not a problem
However this is dangerous as impurities in the pump such as oil and rubbed off bits of metal will be breathed in causing lung damage
How do you clear your ears
That's a beautiful river.
It is! I'm heading back there in the summer.... no homemade snuba helmet with me next time though
+TREADER TUBE
Happy trip!
Homemade snoober diving?.
why the water come,s inside
