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.
+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

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.
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. 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
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.
I did this when I was a kid around third or fourth grade and I filled a backpack full of rocks and the helmet was A 5 gallon bucket attached to the backpack so I didn't have to hold onto the bucket and I use the garden hose duct taped to the inside of the bucket. One of my cousins was pumping the bicycle pump. I spent 20 minutes at the bottom of his eight foot deep pool.
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: ruclips.net/video/8bm9O1OoHII/видео.html
I dived off Mafia Island, Tanzania with local divers who use a steel bucket connected by a hose to a compressor on a boat. As long as the compressor doesn't fail you can free dive and return to the bucket to breath and rest..
+ 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.)
This dangerous I m a commercial part one Diver learned me self from Scottish navy instructors , and I be done well for myself . I bet my instructor found this , he would really insult you as he did with all the British lads offshore . But nice one . As long you are breathing under 2 meters it’s ok . Below that level you need to test co2 . What you could do is give continuity to the air flow , and you should be alright . Once again , NICE ONE
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
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 ruclips.net/video/LEY3fN4N3D8/видео.html
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.
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
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.
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.
+ 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.
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. :)
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.
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
It would also let the water in from the bottom as the air went out the top. You need positive pressure to keep the water out unless you're in a fully-sealed system.
How about if you connect a empty hose to a bucket or something and at the top of the hose you can attach a float so the hose will float above water, giving you the ability to breath underwater! :D
+chaza Yes, but then he would have most none bouyancy so he wont float to the surface he would also get panicked and move more drasticly and use up all the oxygen. And if the pumper would still be pumping his field ov vision would be really low since there would be bubbles inside the helmet, Think before posting.
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
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

Rusty Eel I think this is why he calls it Snuba several times in the video
SSBA… hmm… catchy!
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 :)
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.
says "CO2 is heavier than air" then shows a diagram of CO2 being lighter than air

Or just brethe thrwe tube the other way?
do you even physics? bringing a snorkel in there would empty the helmet
+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

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.
I'm a commercial diver and this is so incredibly dangerous. This guy had many safety back ups but you should never try this. Especially by your self.

This is cool. My grandfather made basically the same thing years ago, but it's made out of metal.
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???
That's a beautiful river.

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
use an electronic air pump for mattresses so u can go to beach and have more air
This is some next level sandy squirl
Loving your videos Tom!
What kind of bike pump did you use cuz I need it.
That looks safe!
I built one a while ago, to prevent co2 from building up i breathed out using a tube that went outside the helmet thing.
Why dont u use a tube to exhale CO2? so it wont mix with the O2
if carbon dioxide is heavier than air, shouldn't it float down instead of up? which causes the carbon dioxide to be pumped out????
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
Dose the bycile pump give enogh air
Don't you need a tube for the co2 to go 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.
okay good I'm glad I'm not the only one
is this a diving bell?
You said CO2 is more dense than air so why would the dry air not push the co2 out the bottom
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.
where is this lake at???
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.
Awesome work
Nice experiment
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
From mad lam?
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
Nice scuba helmet!
What does snuba even stand for?
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.
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!
Greeting to australian from Indonesia..😁 good day mate..
+Leonardo Da Vinci Massolo No one really cares, plus this video was made in the Uk
He’s from the uk
You should of had a device to measure levels of co2 ect to see how much was inside bottel
+Brian farr I agree - I'd like to try this again in the future with some tech and more planning :)
Lake District goals
Where was this
How do you make it
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
wait... if CO2 is heavier than air, would'nt it sink to the bottom?
The drawings are like Leonardo davinchis DRAWINGS
just put a one way valve on the top and then the old air will get released
now when i think about it, that valve will let all the fresh oxygen out aswell
It would also let the water in from the bottom as the air went out the top. You need positive pressure to keep the water out unless you're in a fully-sealed system.
Get a snorkel to stop any danger, I've done this before, it was fun
Anyone know where I can book a trip with this genius?
How about if you connect a empty hose to a bucket or something and at the top of the hose you can attach a float so the hose will float above water, giving you the ability to breath underwater! :D
Good idea!
I cannot wait to watch this guy with his DIY Napkins and Shoe Laces Parachute...
How does he clear his ears?
1:48 the tube wasn't even connected?
good video good crew , dont be scared to improove
Thanks Hugo, we've made lots more vids. Please check them out :)
Why didn't you integrate a snorkel and breath out the co2 with that and breath in o2 with your nose
Better hope your buddy with the air pump is a REAL buddy!
He was exhausted for the rest of the afternoon after this! Thankfully he didn't stop pumping
Theonly problem with this is if you tip over you instantly suffocate.
The only
Yeah because he instantly can't hold his breath you spanner
+chaza Yes, but then he would have most none bouyancy so he wont float to the surface he would also get panicked and move more drasticly and use up all the oxygen. And if the pumper would still be pumping his field ov vision would be really low since there would be bubbles inside the helmet, Think before posting.
+Ethan Bradberry of*
so you know that thats exactly whats going to happen even tho it didnt happen eh?
How do you clear your ears
U guys r so creative
this is similar to medieval diving bells, and they were quite safe.
where can you buy wet suits
What part of the lakes were you in?
Hi Silas, we were down in Grasmere.
ahh good ol grasmere
You couldn't bring one of those inflatable sofa inflating pumps?
Brilliant mate. English eccentricity at its best!
Couldn't you just hook 2 Electric pumps 1 faster than the other that way their would be oxygen and co2 exchanged?
use a snorkle when you exhale , it will prevent most of the oxides out of the helmet while you're pumping fresh air in
whit a small mod you can get read of CO2 just adding a pipe where you can
breathe out in tho the wather
hope at top with tube going out of water to release co2
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
great job wearing orange. seriously its easy to see in water
Finally a useful DIY
