I'm thinking of getting a scuba license and before that I wanted to toy around homemade equipment.

I saw some youtube videos about using coke bottles full of compressed air to breathe underwater, but then I found pic related. It's an 8l-liter hand-pumped bugspray.

I don't know the science behind "the bends" but I know they exist. Should I worry about them if I don't plan on going underwater more than 15 mins, and never more than 10 meters?

Any scuba experts here?

In case it's not clear, I plan on pressurizing this with pure air and going in, breathing when needed just by activating the release switch.

Would this work?

It cost just 25 usd, but I'd like to know if my idea is even remotely plausible to work. I have absolutely no other use for this thing.

There's a pretty good description here of how to build a simple, safe, compressor supplied diving helmet. There's some DUDE WEED LMAO but ignore that.

This style of diving has a proven history and is much harder to fuck up than trying to DIY a scuba cylinder, especially without a regulator.

I skimmed over this article but seemed to be too gonzo for what I'm looking for here. I'm not looking for a fun read, but rather someone who has attempted this before.

As for the regulator, I don't plan on using this on anything bigger than a swimming pool, so any "life support" devices might be overkill.

>>667621

It's quite possible it is a terrible idea... but I still don't know why. I will absolutely desist if given a good reason.

Moreso, I plan on gifting this as a toy to my nephew (fuck a wii-u, you can breathe underwater. how cool is that) whom I love very much so If this is bad I'm very interested in knowing why.

You don't understand. The regulator is necessary to ensure you get air at the correct pressure. Otherwise you are liable to injure yourself.

Because you don't know what you're doing and are liable to be responsible for his death.

Consider just buying him a spare air: http://www.spareair.com/

It's properly designed to PADI standards and will give him a few minutes of breathing underwater before it needs to be refilled, either from a fullsize scuba tank or the compressor at a dive shop.

Thanks. That's what I was looking for.

I'll research on that before I come back asking again.

Okay, here's a few things:
Those tanks are not designed to hold pressure. Without a regulator, they will crush underwater, forcing the air out and into your lungs when breathing.
It's ludicrous to think you could get 15 minutes out of an unpressurized container like this.
I hope your thing is new. Even thoroughly washed and rinsed, you'd have to be mad to breathe air for extended periods of time out of a fucking pesticide container.
Even if it worked, gifting such a thing to a child is irresponsible at best, short of being a qualified diver yourself.

A terrible idea, but you can practice in waist deep water with no danger. Give it a try and let us know how it went. Those things cannot hold much pressure, so you get only a few deep breaths from a tank so the 15 min dive wont happen.

Fuck off fag. Having something even marginally better than a snorkel for 25 usd is neat.

But dying is not desired or worth it.

Would it at least be good enough for 5m deep?

I'm a little afraid of rupturing a lung due to acutely not knowing what the fuck I am doing.

I remember JBS Haldane researched a lot on explosive decompression and mentioned lots of horrible things like ruptured lungs, eardrums, exploding teeth and that bizarre drunkenness that I have no idea what causes it. Also, the dreaded bends.

Anybody has any experience on this pressure-induced bizarre states of mind?

Just buy a full one from any gas station, duct tape a garden hose, and inhale. Takes 5min.

I don't think that's practical for a dive.
I need a way to mount it to my back or a harness.
For the tank to mouth piece I'll probably need some type of adapter and I assume a regulator?

yeah man propane has the nice blue flame because they mix like 30% oxygen with it to sell more fuel for a lower price and have a cleaner burn with less soot. Air has 21% oxygen...

You can also use a propane pressure regulator. Like >>667913, use a garden hose, hook it up to your facemask and off you go!
Don't forget to use teflon tape on the threads. And don't worry about the propane, the molecules are too big to pass the lung membrane, you breathe out the propane and the body takes up the O2 in the mix.

Just don't smoke in the boat or on the dock.

So, wait, you're going to give your nephew an empty bug spray container and tell him that he can breath underwater by pumping it full of air and sucking through the hose?

The full plan was to ask you guys, then try it on myself (35 year old guy) and then give it to him.

I wish him no harm of course. I just think breathing underwater is much cooler than another action figure or a 3DS.

In any case, if this is risky I'd love to know why. I'll probably have my answers when I enroll in scuba classes this winter.

Yes, this is extremely risky, because the air supply is totally unregulated. I have read case studies of children being admitted to the ER with a stroke after having an air embolism in their brain. The children had placed a weighted bucket on their heads, so they could walk around on the bottom of a swimming pool as a "scuba diver." Going even a few feet down compressed the air in the bucket, and the air in the children's lungs. When they surfaced the air bubbles in their blood streams expanded, and they stroked out. Not worth doing to anyone you love.

I sat at the bottom of a 12 foot pool with the hose and nozzle from an electric air compressor for around an hour when I was 10. Nothing bad happened but horrible idea. Just get a cert. it's more fun then dying.

Then get him this: www.spareair.com

If you do the scuba classes you'll be able to buy a full size scuba tank and get it refilled as needed. Your nephew can then refill the spare air directly from the fullsize tank plenty of times before it needs refilling as well.
