How to build a home made scuba diving tank - DIY

This is how you build a home made scuba diving tank.
Never use a sprayer that have been used with chemicals, never dive alone, don't use it in the sea, and always have a certified diver with you when using this.
This video is meant for entertainment purpose only, and we recommend that you don't build and use this. Scuba diving can be dangerous without proper equipment and training.
If you are going to do it anyway, here is what you need for the project:
Garden sprayer: amzn.to/2qxZ9ey
or smaller gardensprayer: amzn.to/2qxYlWP
Weights: amzn.to/2pZLZ7l
Weight belt: amzn.to/2qDASC4
Bagage straps: amzn.to/2pZvrwp
And ducktape: amzn.to/2pZWGql

Zachariah Pohopin I don't think there going deep enough for there to be different pressure in there lungs

[@poekz228]

@Hahshs Hshshs: Because as you go up the air in your lungs expands. If you don't let it out of your lungs your lungs can basically burst and you would have some serious medical issues.

[@poekz228]

@c u: To be practically honest, you are probably right. But you never know how big of a breath they may take down there (they may take the biggest breath they can) or how far down they may try to go. The pool I got certified in was 17' feet deep. That is about another 0.5 atm of pressure on the air in your lungs. If they took a breath at the bottom, the volume of air in their lungs would increase by 50% when surfacing (assuming you are at sea level.) ex: 4 liters would become 6 liters of air. The change would be greater if they were higher than sea level.

[@phillipzx3754]

Although he's using really low PSI, this reminds me of an advanced open water Scuba class I took while stationed in Okinawa back in the early 70's. Part of the training was to breath directly from the tank..NO REGULATOR. The purpose being if your regulator failed, you'd be trained in how to deal with using that high PSI air from the tank. Sort of scary at first. But once you get the hang of controlling the valve, not all too hard to do. These days, backup is the norm.

[@cartervinson4753]

Don't attach the lead weights to the bottle. attach to your waist so that in case of emergency, you can just unlatch it very fast. However if attach to the tank, you have to get those two clips off and then try to take the weights off the tank.

[@herdeefrancisco9161]

4:46 I know I was wrong hearingn it’s funny 😜 thinking he said try and die✌🏼😜

[@hobbesthebrainslug12]

So my understanding is that when he's breathing the pressurized air under too great a depth, and he surfaces, the pressurized air expands inside his lungs and can hurt him, right? So, could someone avoid such injury by "un-pressurizing" the air into a separate tank? Say you had one tank under pressure, and a second one that was not, and the first tank fed into that tank before you breathed it.

[@Fullftronix]

Nope, the problem isn't that he has compressed the air into the tank. It's fact that under "pressure" air can be compress and when you dive the water pressure is what is doing the compressing. So say you take 1 litre of air in a bottle at see level (0m) and then you dive down to 10m. There is still 1 litre of air in bottle but it will be compresses to around 500ml or half the amount of air and has crushed itself. (because of the water pressure around you) Now you want to fill a second 1litre bottle (at 10m still) but if you note the bottle we fill at the surface has half as much air, So where going to need to but 2litre of air. Now as we return to the surface the first bottle begins the return to normal but the second bottle in beginning to swell up. The further up you go the more the second bottle swells up and then BANG it's bursts. The same thing can happen to your lungs when you breath in underwater.

[@americanallthewayredneck3917]

Justin David its pressure and volume effected by atmosphere..every 33 feet an atmosperic change to pressure and volume occurs...Holding your breath below 33 feet and coming to the surface could cause an embolism...over inflation or bursting of the lungs...

[@macadoua4847]

Ryan Xuereb: Although its true that the water is doing the compressing, the air pressure inside the tank is still higher at sea level. As well as this, as far as I'm aware, and I could be wrong, I haven't taken SCUBA lessons, the tanks do not get compressed by the water because of their rigidity.

[@macadoua4847]

Justin David, you are smart. Why didn't I think of that. Of course you could be wrong, but it seems true.

[@rubinmendoza13]

[@jennakatze5401]

YouToob or don't use this for depth because it has no regulator or any way to bring the air to the correct pressure

[@alextell7019]

@David Chatterton because he doesnt breath in while underwater its pretty fucking simple, when you breath in under water the gas is more compressed so when you surface it expands which can rupture your lungs

[@TARS20]

You can hold your breath underwater as long as you're neutrally buoyant and don't ascend nor descend.

Jenna Tolls why exactly does a regulator increase safety? A regulator just brings the pressure of the air to environment pressure, but its the same air. Its more like a comfort thing

[@jennakatze5401]

[@Berkcam]

No, you won't get 90 seconds - this guy doesn't even get 2 breaths from it. Plus, if you have normal sized adult lungs the volume of air required for swimming would be around 28 - 35 litres per minute at surface pressure. This piece of plastic shit is just over 8 litres volume which equates to 1 and a half breaths surface pressure. It cannot be pressurised to anything near the pressure required to provide more than 1- 2 breaths at just 1m depth. From a Professional Diver of 40+ years.

[@tidybananas3954]

Is this safe for a 5 ft deep pool and is having pressure air in lungs safe

[@russelrlthomas]

No it is not safe for an untrained person to breath compressed air even at 5 ft, because air embolisms where air expands as you get closer to the surface have injured people at shallower depts than that. A trained scuba diver could probably use this reasonably safely because they are trained to release air as they surface to avoid embolisms, but should not and it is unlikely that even 1% of trained divers would be foolish enough to use such a contraption. .

[@andyroberts4089]

People trying your idea can sustain a lung over expansion injury (i.e. air embolism) in just 4 feet of water if they fail to breathe continuously as SCUBA divers are trained to do. This is a serious and life threatening injury. You have been warned by a number of commenters. Now you should be liable for people who are injured by implementing your instructional video.

[@andyroberts4089]

A lung over-expansion injury happens when air breathed at depth is held in the lungs while ascending to the surface. The air expands and ruptures the alveoli in your lungs causing massive hemorrhaging. Your alveoli are only one cell layer thick between the air in your lungs and your blood supply. It does not take much force to sustain this injury and the damage is permanent if you live.

[@-BWS-]

Nah, If people get injured t's their fault for doing this DIY.

[@andyroberts4089]

I do happen to dive for a living. So that makes me a pro by definition. 😬 I'm just concerned kids or even adults will try this and sustain a life-long injury.

[@andyroberts4089]

Island Mike you have absolutely no idea what you are talking about.

[@engineer0239]

Oh my god you dont know anything about what your talking about, but ok lets Do the maths. If you inhale at 4 feet depth and then go to the surface thats a pressure drop from about 1.1 Bars to 1 bar. Every 1 bar a Gas doubles its volume so if you inhaled 5l at the surface you have 5.5l in your lungs. So whats the big Deal? After all getting a lung overexpansion by holding your breath is very hard and it will force you to exhale.

[@dfmdlp4358]

+Christian Wedoy hey, amazing Project, I want to build it too, but before I want to know how often you can breath under water, until the tank is empty?

[@Christian_Wedoy]

+DFMD LP it says in the video. 2-4 min

[@Daniel-vp7gw]

Would this be okay for a 13 year old in a 1-3 meter deep pool?? I am really fascinated with scuba diving but I have a low budget.

[@fjc_adventures4359]

If you let your children do this, they should be taken away from you and placed in someone else's care.

[@DroneMee]

😂 what a terrible idea. In a pool okay the guy that takes this into the ocean 💀lol

[@predator6707]

Do not try that that is so dangerous you do not want to hold your breath while you're underwater breathing air I would not recommend this to anyonedangerous dangerous dangerous

[@summerb7579]

ppl scuba dive...

[@djvendetta2325]

bro put a regulator on it it's not that hard

[@srirachadolphin3782]

Still gonna make it

[@kjetilavset9503]

hi Cristian, i tryed this with a spray tank that you fill with a compressor to 8 bar. had a ok dive to 15-20 meters. When i was emty of air i whent up. but after I came up I had some pain in my elbow and sholder, it whent away after a week or so... do you think tjis hs something to do whit the air quality?? 🤔

[@z-RT-z-iq3cn]

Dude u know that u need to blow air from your lungs when you go to surface? Because air is more compressed underwater(it means ur lungs could explode)

[@bradkiviaho9712]

I have a question:) I have a homemade 7.5L Garden sprayer scuba tank can I get the bends if I go down more than 6m? Thank you please reply to this message I want to know

[@amfbat1]

No you can not. But when you don’t breath in breath out !!!! So protect your lungs. And I don’t recommended this if you are not a experience diver. // instructor Ps I found probably like to try it out in a safe place whit some dive friends. Dive safe

[@DontScareTheFish]

You won't get the bends (DCI) as there isn't enough air in the sprayer. You would however have a good chance of getting a barotrauma. A barotrauma is where the lungs get over pressurised and burst and can happen in as little as 2 meters.

[@lucagreen7436]

Guys i have a PADI and i have made one of these with two tanks and it can be dangerous but if you only dive like one metre it won't kill you i have dived multiple times with my homemade one and i have yet to die.

[@tomernovikov3650]

LG Epic i want to build one too

[@djvendetta2325]

it's not hard to buy a second stage regulator so you can breath in and out through it I don't see too big of a problem with that

[@srirachadolphin3782]

Finally one positive one

[@mcpuckles1459]

Instead of taking the risk using this just get certified and buy your equipment

[@matthewstutts273]

i hope he understands that while that might work in shallow water, it could easily and catastrophically fail at depth. (unless his sprayer has adjustable pressure valves)

[@hemmy2276]

How deep can u go with the limited air u got? Also does it work well in a lake?

[@Christian_Wedoy]

+FaZe Neon Not deep. I would not recommend going other places then the pool with this

[@samuraijackxx3945]

Super dangerous, use a proper tank when diving

[@dinkelheit88]

SamuraiJack xx It's a public pool not a dive

[@ferrosplice8460]

It really isnt that dangerous. People are going to use this because they wanna dive at crazy depths. They use this because they wanna explore a lake near their house, or swim down a rive and see the fish without have to surface for air as often, little things like that.

[@jamppa4693]

Your just like my mother :)

[@georgegdl3606]

I would not recommend this

[@MegaRogelio23]

Good video some people are just criticize but I don’t see them doing a video to show better. I think is a good video.

[@dakotakarow3041]

Thank you I made my own scuba tank from this video

[@RadddahTat]

Remember to release the air out before you surface or your lungs will explode

[@jennakatze5401]

RadddahTat they won't explode they just will get badly damaged because it's missing a regulator

[@engineer0239]

Jenna Tolls what??? A regulator prevents your lungs from overexpansion??? That Are two completly separate things?! Its lot like its a magic pipe going in your mouth and keeping your lungs together?! If you hold your breath even a regulator cant Do anything

[@richardrounce7138]

Is this not dangerous? If I were to try this with a small water sprayer as a spare air tank, how would I do it safely?

[@youtubechannel8155]

How do you know how much weights you need

[@brettkramer]

Epic Bad Idea, for the sake of your own safety, do not try this. This is a PADI Divemaster, Certified Rescue Diver and Certified Emergency First Responder talking !

[@jennakatze5401]

Brett Kramer sadly no one listens

[@marcinw5642]

Can i ask why? I had the same idea as the author of this video, but fortuantley i found this video before trying to dive with this "equipment". Is it really so dangerous? I wanted to go like max 4 meters underwater for 5 breaths from this bottle. Would it kill me?

[@paraphenaliac4657]

Marcin W YES

[@magiclarry7688]

Brett Kramer people who don’t heed your advice are likely to need your services one day.

[@Berkcam]

If I had to build and use something like this to escape from a communist prison camp... I would. However, in normal life there is no need to risk drowning or a burst lung with such a piece of crap. Someone on here has already commented that they 'forgot' to clean out the spray tank before use - do you not see how dumb this thing is when there are such dumb people in the world? No one has considered what would happen should anyone swim down to 10m with this plastic thing on their back but I can tell you this; It will most likely implode very quickly - leaving you sucking water through that hose. You can check my credentials through my underwater videos on my channel, they were all filmed by me - a former military and now professional oilfield diver and strongly advise you all to pass this idea bye.

[@CanIbeWithThee]

I hear you but so long as a person only used something like this in shallow water, no more than 20 feet, I think it could be relatively safe... of course there are a lot of idiots out there. Nevermind 😉

[@feedbak007]

Couldn't agree more (Certified 16years, rescue diver, Nitrox qual.)

[@themightywog1018]

Berkcam Would this be safe in a pool no deeper then 2 meters?

[@Berkcam]

@@themightywog1018 no, you can suffer a burst lung from even that depth. Just look at the piece of crap 😆

How to pass out and die 101

[@seikibrian8641]

Notice how the video keeps cutting away; we never see him actually take more than one breath from this piece of junk.

[@seikibrian8641]

So most people wouldn't be interested in a "scuba tank" that only gives one breath, but there is no evidence that this piece of junk can do otherwise.

[@ferrosplice8460]

Or maybe the video cuts away so we dont have to just watch a dude chillin under the water for a minute. Just a crazy, crazy idea of mine.

[@engineer0239]

Theoreticly this thing can Provide 10l * 4bar (typically max for one of those) -10l is 30l of air which is about 4-6 breaths At that depth depth doesnt really matter

[@ddlux]

at 4.47 you said and them go die? because i heard that maybe you said dive but idk

[@LoveWins]

I highly recommend using flex tape as it would be waterproof as duct tape is terrible in wet environments.
