Underwater breathing. No scuba tank, no compressor just with your own muscles.

[@DriftWorn]

Pretty neat! Love your out of the box thoughts

[@BrickyMPG]

just like the exo lung this is good!

[@Mr.Trembling-eye]

I had a system similar to this, I dived up to 2 meters under water and hung, but no air came, then I drowned and died terribly.

[@normtekani4453]

Very clever!!

[@anthonyblaise7804]

Oh thats looks great

[@theoldsailmaker6408]

There was a commercial made produkt called 'diveman' . I used it a lot . Guess it had a bit more volume, was pretty hard at 20feet to use.

[@Uhi-puhi]

that maybe something that would work 2-3 meters deep max. the deeper you go the harder you need to work to pump air from the surface. The harder you work - the more you need to breathe. The more you need to breathe - the warder you need to work. Hope you see where it goes)

Thanks for the awesome video on how it works! Is the diaphragm PVC or Hypalon and what technique did you use to glue it? Cheers!

[@JashTheLandlord]

Interesting stuff

[@robertmuller7391]

Wondering how deep you have gone?

[@shanebrennan4657]

I have been thinking of this myself and surprised to find someone has done this. How many litres of air would you say each stroke brings into the air chamber when you straighten your legs?

if the section is circular the calculation at 5 meters gives me: 1.5e5*.1^2*3.1415/4=1178 N or about 117 kg. It is not a force that the legs are not able to apply. I weigh about 100 kg and I am able to carry several tens of kg, so I think that the legs can apply this force without difficulty. Let's say that 5 meters seems to be the operating limit. Which is not very little: it is comparable to the operating limit of an oxygen rebreather.

In America we call this Jerry-rigged scuba diving. Clever--yes. Risky--yes. Stay safe.

R.I.P Mr. random scuba man on KZbin🙏🏻

[@roadstar499]

Pretty cool..but a good hookah setup has advantages over this..thanks for sharing

[@luisgomez8635]

Diving? I just want one of these for the jacuzzi

[@nikachxaidze4574]

Wheare i can bay?

[@joshschannel4409]

I remember seeing a video on here about a product like this one. I believe it's called EXOLUNG?

[@RobbyRockaholic]

Yeah it’s like exactly the same I’d like to see one with a hand pump

[@carlbroker]

Always carry bailout IMO, be safe and have fun!

[@andysworkbench]

Absolutely! Thank you very much for your comment😀

[@timtim8468]

I'd recommend to put side release buckles everywhere, to get rid of it all if needed.

[@fredvela6994]

I'll buy one if you are willing to make it for me. I just dont have the time to do it myself. I'm only g diving 15 feet, no more than that.

[@engineer0239]

This only works slightly below the surface. The deeper you go, the harder it becomes to pull. With a 10cm diameter pipe, at 5 meters depth, you would have to pull on that string with about 1500 Newtons, which is about 150kg or 330 lbs! For general purpose diving it's completely unusable.

Sorry, honestly, I don't know what either of us are calculating anymore. In the beginning he says it to be a 125mm tube. The cross sectional area is (12.5cm/2)^2*π= 122cm^2. At 5 Meters, you have 0.5 bar, or 5 N/cm^2. So 122*5= 610N or 62kg, which is doable. Sorry again, I was probably high or smth...
