Anyone who says you should be qualified to know what your doing is not 100% right... I mean I've dived with PADI (Put Another Dollar In) OW certified people who had no idea what they were doing at times. With the video... just watch your self guys like @mattmanavy said.. over-expansion of the lungs is serious shit.
yes JOIO84 but there are good dive stories and videos on the net also. Try the myscubastory site. Type myscubastory into google and its the first one .. enjoy
Sorry - but kids shouldnt be doing this type of stuff. There is a lot of actual science behind diving. You need to take lessons to understand what you are getting into. This is the type of video that should be pulled by youtube due to the dangers someone can get themselves into
lowman22 there is also another site called myscubastory that has diving stories like accidents shark encounters etc. type myscubastory into google and its first one i think.. good luck
It´s a cool hobby, really risky, but cool. Hope you don't get killed. Anyway if you are serious about building these kind of stuff you should consider taking a "real" altenative air source with you in case something fails and also a better BCD system with a dischargable weight belt. Just an idea! I'll stick up to my "comercial" equipment anyway ;)
a full breath of air taken down as little as 1/5th of an atmosphere (6ft) underwater and held while you assent will pop your lungs and you wont even realize it until you caugh up blood and get a brain hemmorage. Important things like this are the reason people undergo dive training so they don't kill themselves...be careful kid..
@mattmanavy Yes indeed. the volume of your lungs will increase 100% from 10 meters if breathered under pressure! Another danger of over expansion is that you pop a lung just enough to get air in your chest cavity stopping you from breathing in....horrid way to go! :(
@mattmanavy So would it be accurate to say that if I were at 10 meters and ran out of air, if I had one breath still in my lungs to surface with, I should let it out little by little as I ascend?
@slunkmonky That would be correct if you inhaled the air under pressure while under water. If you are holding your breath from the surface then you don't need to but it wouldn't hurt you if you did.
ya not safe cool but not safe even traces of other gases other than oxygen and nitrogen can cause convultions at depth and like what xm4tr1x said trace oil particles from a standard compressor can kill you...be safe and certified.
with real scuba gear the regulator delivers air at the the ambient pressure. Meaning the air is at the pressure of the water surrounding you. thats what keeps your body from imploding. you should not go any deeper than pool depth with this.
@1237jjm There's no way you'll implode with a self contained system like this. I can't see if they're using a demand regulator but I'd guess that for the price they aren't and instead opted for a manually controlled air valve. Too little air and they just can't take a breath.
The biggest issue for them is if they panic and clamp on the mouthpiece and don't shut off the air valve or if they hold a full breath and ascend more than a few feet. Both cases will give them an embolism.
@1237jjm Your body is mostly liquid. It will not implode. And your lungs can fluctuate as they do everytime you breathe or freedive. The danger here is holding a breath of compressed air and ascending. This will cause an overexpansion injury. Even from the shallow depths of a pool.
dont listen to them, you are not going to get decompression sickness in a 10 ft pool. The maximum no decompression limit is 130ft for 10 mins. Its perfectally safe as long as there was no chemichals used in that container previously.
@planer002 You are right about the no deco limit. But that does not mean you can not get the bends at less depth. The deco limit only tells you when it is absolutely necessary to make regular deco stops.
Also, there are several medical conditions that can lead to a higher absorption of nitrogen into the blood stream. And I witnessed first hand a diver getting the bends at only 15 feet. Just seach google for bends shallow dive I unfortunately can't post a link in here :-(
Lipoid Pneumonia. Look it up. Making your own SCUBA gear, especially the way you have designed it, CAN and WILL kill you! Even if that tank is a basic hand pump pressurized chemical spray tank, oils and lubricants exist to keep it working smoothly. Those oils vaporize under pressure and enter the bronchial passages and damage the lungs. SCUBA air is cleaned, filtered, and processed to remove impurities. You are playing with danger and will likely end up dead or seriously ill if you continue.
Its not a bad concept. As long as you are certified (as you guys mentioned you are) you have the basic skills to react in an emergency. Even with name brand gear, most accidents are a result of user error. Stayin above 15' and you will be okay. I actually like this idea and may give it a shot for my own sake (I too am certified). Be safe and have fun!
DIY SCUBA, Nice, But at least learn the basic how not to Die. Like, if you were to run out of AIR on the bottom" YOU CAN NOT HOLD YOUR BREATH TO COME TO THE SURFACE!' Type lung overexpansion into your browser. Good luck!
Good for you! I'm a long time scuba diver and disagree with those that go nuts and tell you you're crazy to do this. My advise is: 1) breathe - never hold your breath, especially when ascending, 2) Don't go below 30'. Hey, fun stuff is sometimes dangerous. Getting certified doesn't guarantee safety. Just be aware that the chances of equipment failure is FAR more likely with this home made stuff and act accordingly.
ive been wanting to make some homemade scuba gear for a while ive tried many ways. this is great for diving less than 15 ft but anything else u definitely need proper gear i can honestly see why this would cool cuz u can have just as much fun diving in 10 ft of water compared to 100 ft. and yes its very expensive to dive properly u can get certified for under 300 400 dollars and rent gear but to actually but gear costs thousands of dollars.
I just bought my setup tonight, and it did come to about fifty dollars. This is how my setup goes... First off I grabbed a 2 Gal. sprayer tank rated at 65psi. I then got some high pressure line and a pneumatic tool pressure regulator to bring it down from 65psi to around 20psi. I'm in the process of building it. I plan to make a nice detailed video with a test run and post it for further improvements!! If anyone has ideas post!
Haha. I wouldn't dive with that on but "should not be attempted by anyone without proper scuba training (like us)".. Okay, you dont have proper training.
I believe that's not safety because you aren't using dry air.
Ingenious. People are ANAL!!! haha. It is understood that is can definitely be dangerous, but jesus... if these guys knew enough how to build this then they are obviously not incompetent morons. Great job, keep it up. The world needs more people like this.
As far as I am concerned scuba should either cost $5000 to get certified or be a 5 months long program. I would have to say that majority of recreational diving fatalities or injuries are attributed to new divers. Get certified in 2 weeks, fly to cancun and capow another person was rushed to a hospital with little chance of recovery. I travel all the time and you would not believe how many stupid stupid stupid newly certified divers are out there. New divers have no place to dive at 90ft .
Lets not start making assumptions on what is safe. Safety stop is there for a reason. If you spent an hour under water and went straight to the surface you will get bends. There is no way around it. Now you might get light version of bends and feel like crap for next 4 days or you may pass out on the boat. Scuba diving comes with responsibilities and that is why you are required to get a certification and thus learn how to dive safely. Kudos to these 2 guys swimming in the pool. Just be safe.
How the H*** will uspend an hour under water with a tank that holds 2 us gallons of air at 40 Psi.???? Just like someone else sain just don't hold ur breath on the way up ... PS PADI is a raquet to make sure that only those wealthy enough to pay THEM 4-5 hundred bucks to get 'certified' can dive. Y does it take 500 to learn that
P1V1=P2V2 and that as u go down pressure goes up and gasses compress that and gas soulibility goes up w/ pressure ... if u took chem or physics u should know that.
You can't go and buy a full set of scuba gear and fill tanks with the knowledge of physics and/or chem - it's a regulated industry, paying the $500 makes life a lot easier than trying to argue the point that you're more educated than they are..
Scuba tanks require filtered "dry air". 1st ;so the moister in the air wont corrode the tank and 2nd; and more importantly, so the moister doesn't condense in your lungs and give you phnemonia. Looks like a fun experament but be careful.
@xm4tr1x xmilkman can correct me if i'm wrong but it looks to me like they used a pump style chemical sprayer in their design. No motor driven compressor involved. hopefully no chemicals either ;-) Clever!
@AquariumMania Did you really just call me stupid? A pump sprayer has a hand pump on it, you don't use an air compresser, and of course its filled with compressed air
I'm a diver and I must say, this looks fun. But I would never consider any real diving with it ;-)
The trouble with diving and dept/pressure is this:
If pressurised, more air fits into your lung. This makes you absorb more nitrogen in your blood than under surface conditions. When you go up too fast after a longer dive, the excess nitrogen is released from the blood too fast. Like opening a soda bottle that has been shaken. These bubbles can then destroy tissue. It's called "The Bends"
@dedch1 I'm quite certain they won't be hitting their NDL's with 2 minute dives. If anything the sawtooth dive profile would be the cause of issues but even still I think that is very slim. If they were to get to any depth than their bottom time would diminish rapidly enough as the ATM pressure increased that there still wouldn't be any on gassing. Just my two cents.
Deep diving with this!? That would be a one way ticket :P
Anyway if somebody's willing to try this - instead of builing a homemade scuba gear, you may consider tieing a rock to your neck - not only easier but also more effective.
@dedch1 yeah, but you can still get deco sickness with proper scuba gear. the thing i would warn this kid about is to not hold your breath while you're ascending so you don't go and pop a lung. All that aside, props for a sick setup
Don't forget though that you can't reallly "on" gas and load up with nitrogen above 9 meters. So 8 meters, 7, 6 etc would be fine...they are no stop dives...
@dedch1 Aww man the bends is not cool a buddy of mine got when we went scuba diving for spring break! He had to go into one of those decompression chambers for a while! And if this kid holds his breath and come up he can get that lung over expansion crap that hurts really bad!
I think you might want to recheck your numbers. 60ft if you were under for an hour you would have to do a deco stop before surfacing, other wise there is a good chance for DCS
No need to do safety stop at 60 feet as the dived did not go within the three presure gtoups of the RDP or 100 Feet. If the diver did go to 100 feet, he or she need to do safety stop. Though it's a good practice to do so.
I made a "UBA" (it's not self contained:) ) a while ago I have a 1.5 cu. ft. helium tank which I pressurize to 100psi. the tank sits on the edg of the pool and I have a 20ft. hose. I can stay 8 ft. underwater for 20 minutes.
Ok so people make it sound extremely dangerous to go beyond 10 ft I guess cause when coming back up to the surface you risk expansion or whatever my question is how far down could I swim without gear just holding my breath is there much any risk to it? I am also not what you would consider small if that makes any difference I have some muscle mass to me. Ive never been diving really other than swimming in a pool.
There is no risk to swimming with no scuba at whatever depth, the reason why there is an inherent danger to fast ascents with scuba gear is that the deeper you go the higher the pressure that you need to maintain in your lungs to breath comfortably. Quick example, at the surface, you breathe at 1 bar pressure, at 30m, you breath at 4 bar, if you surface with 4 bar pressure in your lungs, your lungs will expand to 3 times the size and tear. Don't hold your breath with scuba!
This is actually ingenious, but what makes it dangerous is if you know the science behind diving or not. Do you know you can 'blow a lung' by ascending just 1 foot when breathing compressed air? I hope you did your science first. If you did, then BRAVO! Yes, I agree with the other poster who said, "if some moron told jaques not to make the aqualung where would we be?". So, do the science, form a hypothesis, control the experiment. I hope you did that!
i did this about three months ago and my i couldnt breath because my chest was compacted from the water. is there anyway that i could get around that?
pretty sweeet i tried this today and i went 3:30 with it, thanks for posting this vid.ive tried a long snorkle before but the pressure makes it so u cant inhale it just forces all the air out of ur lungs
It is ingenious and i think its great that they like diving but maybe im just an idiot who takes things to cautiously but if they dont know what they are doing i still dont think its a great idea if they do then more power to them
i mean, unconventional yes, but why disapprove someone trying to experiment, invent, and expand their knowledge of diving? if some moron told jaques not to make the aqualung where would we be? diving with any equipment has its risks. not to mention maybe they are scuba qulified, and can handle if the apperatus didnt work and how to come to the surface and avoid Pulminary overinflation syndrome or other problems, its not like they dont have readily available access to the surface.
I am a PADI instructor and I would have never imagined in 100years to factor a working homade scuba tank in that fashion you have to be proud of yourselfs "BRAVO BOYS" "BRAVO !!!!"
you people posting negative comments are idiots. these boys have come up with and ingenious home plan for an underwater breathing devise I'll bet if Jaques were alive today He would be very impressed. and the boys were never in any danger of overlung expansion in the shallow water they were in, and probably new it, and more than likely have some education of scuba or would not have known how to build it in the first place. I think its brilliant.
As a Padi master level diver i think you guys are idiots
i think its great that you want to dive but get certified and buy real gear serious damage to your body can result if you arent careful diving is fun and safe if given the respect it deserves
Thats because PADI idiots make everyone believe they have to spent thousands of dollars in gears and instructions before getting your body 2 ft down the surface.
Air compreses when you are deeper underwater and expands as you approach the surface. Imagine your lungs as a balloon filled with air. On the bottom of the pool the balloon would be compressed and take up less volume, as you surface, the balloon would expand. For this reason, you should never take a full breath of air on the bottom of the pull and hold it as you are surfacing.
That's ok and all... but I can hold my breath for at least 3 minutes. Creative though. Ever think of getting actual gear and go scuba diving for real? - have fun!
Oh, and another thing, always make sure someone's there with you when you experiment with your dive gear. Yeah, and my friend, the one i work on this stuff with, wants you to try and beat our underwater record. 31min 13sec underwater( and that was two of us using the same system, we had a third guy watching out for us)Best of luck!
See if you can design one yourself! You'll stay under longer! Ive been experimenting with stuff like this since 5th grade(freshman in college now) and i know a few tricks and methods to make things more efficient. If you got any questions let me know!
The ambient pressure from the surrounding water actually compresses the air in the tank for me, so its ready to breathe. I believe your system looks like a free flow system with an on/off valve. Mine does as well. The only problem with mine is that its not nearly as portable. I must say that portability is a good thing.Got a challenge for you though, me and my buddies are working on an truly on-demand regulator( already got one now but only works at low pressures) built from scratch.
Nice work! very creative using a garden sprayer as a tank. Ive got a similar setup, but the air tank is an inverted plastic bucket(5 gallons) weighted down, ideally to the very bottom of a pool linked to a compressor by 20 ft hose. The compressor keeps the bucket full as i breathe from another hose, also connected to the bucket. the breathing hose is attached to a on/off valve and a mouthpiece with purge.
at least the one's that didn't kill themselves. Just get proper kit and training if you plan to go anywhere deeper than your swimming pool. And be sure to breathe out as u surface if something does go wrong, burst lungs are not going to be a nice experience, and most commonly happen in shallow water. (Read about Boyles Law)

Now you might get light version of bends and feel like crap for next 4 days or you may pass out on the boat. Scuba diving comes with responsibilities and that is why you are required to get a certification and thus learn how to dive safely. Kudos to these 2 guys swimming in the pool. Just be safe.

How the H*** will uspend an hour under water with a tank that holds 2 us gallons of air at 40 Psi.???? Just like someone else sain just don't hold ur breath on the way up ... PS PADI is a raquet to make sure that only those wealthy enough to pay THEM 4-5 hundred bucks to get 'certified' can dive. Y does it take 500 to learn that
P1V1=P2V2 and that as u go down pressure goes up and gasses compress that and gas soulibility goes up w/ pressure ... if u took chem or physics u should know that.
immcguyver07 2 years ago
You can't go and buy a full set of scuba gear and fill tanks with the knowledge of physics and/or chem - it's a regulated industry, paying the $500 makes life a lot easier than trying to argue the point that you're more educated than they are..

zorcthedestroyer 2 years ago
Scuba tanks require filtered "dry air". 1st ;so the moister in the air wont corrode the tank and 2nd; and more importantly, so the moister doesn't condense in your lungs and give you phnemonia. Looks like a fun experament but be careful.

joesteed7 3 years ago 2
I'm a diver and I must say, this looks fun. But I would never consider any real diving with it ;-)
The trouble with diving and dept/pressure is this:
If pressurised, more air fits into your lung. This makes you absorb more nitrogen in your blood than under surface conditions. When you go up too fast after a longer dive, the excess nitrogen is released from the blood too fast. Like opening a soda bottle that has been shaken. These bubbles can then destroy tissue. It's called "The Bends"
dedch1 3 years ago 13
@dedch1 I'm quite certain they won't be hitting their NDL's with 2 minute dives. If anything the sawtooth dive profile would be the cause of issues but even still I think that is very slim. If they were to get to any depth than their bottom time would diminish rapidly enough as the ATM pressure increased that there still wouldn't be any on gassing. Just my two cents.

Decompression sickness after 15 min @ 10 feets - impossible
However without proper training, if you run out of air - barotrauma is what awaits you on the surface (and it's not gonna be pleasant)

@dedch1 yeah, but you can still get deco sickness with proper scuba gear. the thing i would warn this kid about is to not hold your breath while you're ascending so you don't go and pop a lung. All that aside, props for a sick setup

@dedch1 Or DCS/Decompression Sickness :)
Don't forget though that you can't reallly "on" gas and load up with nitrogen above 9 meters. So 8 meters, 7, 6 etc would be fine...they are no stop dives...

How much pressure?
your hoses and valves are probably to small, 3 feet under water isn't much pressure.
gizmoguyar 3 years ago
there's no reel risk below 40 ft.(below as in not as deep)
evan at 60 ft. one would have to stay down an hour and then come up really fast to get decompression sickness.
Just know the science.
gizmoguyar 3 years ago
I think you might want to recheck your numbers. 60ft if you were under for an hour you would have to do a deco stop before surfacing, other wise there is a good chance for DCS
Buga8tr 3 years ago
No need to do safety stop at 60 feet as the dived did not go within the three presure gtoups of the RDP or 100 Feet. If the diver did go to 100 feet, he or she need to do safety stop. Though it's a good practice to do so.

MidnightMarrow 3 years ago
Ok so people make it sound extremely dangerous to go beyond 10 ft I guess cause when coming back up to the surface you risk expansion or whatever my question is how far down could I swim without gear just holding my breath is there much any risk to it? I am also not what you would consider small if that makes any difference I have some muscle mass to me. Ive never been diving really other than swimming in a pool.
MidnightMarrow 3 years ago
well i have a friend on the coast who dives around 50-200 ft so you should be safe diveing anywhere from 10-75 ft
gallade99999 3 years ago
There is no risk to swimming with no scuba at whatever depth, the reason why there is an inherent danger to fast ascents with scuba gear is that the deeper you go the higher the pressure that you need to maintain in your lungs to breath comfortably. Quick example, at the surface, you breathe at 1 bar pressure, at 30m, you breath at 4 bar, if you surface with 4 bar pressure in your lungs, your lungs will expand to 3 times the size and tear. Don't hold your breath with scuba!

gizmoguyar 3 years ago
This is actually ingenious, but what makes it dangerous is if you know the science behind diving or not. Do you know you can 'blow a lung' by ascending just 1 foot when breathing compressed air? I hope you did your science first. If you did, then BRAVO! Yes, I agree with the other poster who said, "if some moron told jaques not to make the aqualung where would we be?". So, do the science, form a hypothesis, control the experiment. I hope you did that!

i mean, unconventional yes, but why disapprove someone trying to experiment, invent, and expand their knowledge of diving? if some moron told jaques not to make the aqualung where would we be? diving with any equipment has its risks. not to mention maybe they are scuba qulified, and can handle if the apperatus didnt work and how to come to the surface and avoid Pulminary overinflation syndrome or other problems, its not like they dont have readily available access to the surface.

you people posting negative comments are idiots. these boys have come up with and ingenious home plan for an underwater breathing devise I'll bet if Jaques were alive today He would be very impressed. and the boys were never in any danger of overlung expansion in the shallow water they were in, and probably new it, and more than likely have some education of scuba or would not have known how to build it in the first place. I think its brilliant.

As a Padi master level diver i think you guys are idiots
i think its great that you want to dive but get certified and buy real gear serious damage to your body can result if you arent careful diving is fun and safe if given the respect it deserves

Thats because PADI idiots make everyone believe they have to spent thousands of dollars in gears and instructions before getting your body 2 ft down the surface.

AgUiLa4EvR 3 years ago
Air compreses when you are deeper underwater and expands as you approach the surface. Imagine your lungs as a balloon filled with air. On the bottom of the pool the balloon would be compressed and take up less volume, as you surface, the balloon would expand. For this reason, you should never take a full breath of air on the bottom of the pull and hold it as you are surfacing.

rossettiman 3 years ago
The ambient pressure from the surrounding water actually compresses the air in the tank for me, so its ready to breathe. I believe your system looks like a free flow system with an on/off valve. Mine does as well. The only problem with mine is that its not nearly as portable. I must say that portability is a good thing.Got a challenge for you though, me and my buddies are working on an truly on-demand regulator( already got one now but only works at low pressures) built from scratch.
rossettiman 3 years ago
Nice work! very creative using a garden sprayer as a tank. Ive got a similar setup, but the air tank is an inverted plastic bucket(5 gallons) weighted down, ideally to the very bottom of a pool linked to a compressor by 20 ft hose. The compressor keeps the bucket full as i breathe from another hose, also connected to the bucket. the breathing hose is attached to a on/off valve and a mouthpiece with purge.

at least the one's that didn't kill themselves. Just get proper kit and training if you plan to go anywhere deeper than your swimming pool. And be sure to breathe out as u surface if something does go wrong, burst lungs are not going to be a nice experience, and most commonly happen in shallow water. (Read about Boyles Law)
