      Considering how willingly he comments on the badness that can happen… And the fact he actually pressure tests his builds AND does the math … I’d say he’s a far cry from a company that pressure tests their builds with passengers. Live. Breifly.

      I appreciate his content. Its interesting and hearkens back to old youtube content before it became a glorified ad stream. Its a dude doing a thing and taking you along for the ride. If you are entertained? Cool. If you learned something? So much the better.

      Check out his videos. If anyone knows how to properly calculate pressure for any application, it’d be Hyperspace Pirate. I agree this idea is silly and unnecessary (as he acknowledges himself), but it’s done safely. He’s done many projects more dangerous than this.

          I’d give him credit for explaining (frequently) how dangerous what he is doing is… and frankly his willingness to quite literally showcase what the result of the badness can be.

          Too few channels do either. And there’s some wildly dangerous shit posted daily that is over-edited and rarely even touches on the very real dangers of what they showcase. It gives the illusion of safety to people who likely don’t understand the science / risks.

          So? He is a hobbyist who documents his projects, he isnt advocating that people do all the same stuff he does. People have accidents all the time, it doesnt negate their intelligence.

            I’m not saying this guy is too dumb

            I’m saying half the internet is too dumb for this and people with zero knowledge and experience will try to replicate this and die

    First thought was nope nope nope to diy diving helmet, but looks like it would be quick to remove so not too bad. Feels way overengineered if you just wanted to sit in your pool though.

    I know snorkels get into problems with depth as your lungs can’t inhale against the pressure. But I am curious how deep that would get you. The dead air in the snorkel is another issue but you can solve that easily with some valves or just exhaling through your nose. Bit impractical to have a very long rigid snorkel but a tube attached to a float could work. Just not sure what the depth limit would be before you can’t fill your lungs anymore. 1m? 5m?

      His design is essentially a diving bell helmet with a pressurized feed of air from an air compressor, so the lungs don’t have to overcome breathing through a snorkel. He plans to use it in shallow areas around Florida, he was only testing it in his pool.

          Considering the other content he’s produced I’d say this guy at least understands pressure reasonably well. The crab reference is a nod to the scary shit pressure can do to … Living things. (There’s some really nsfl shit out there on the topic.)

            I’m sure he understands it all

            Will all the viewers who are going to replicate this thing understand it?

              Certainly not.

              The first time I read how to make thermite, smoke bombs, etc… I definitely was too young to fully work out the ramifications of my actions.

              With that said: how many people ignore warnings that are clearly posted? That’s a human flaw. It’s not age gated. Needing to see for ourselves that the stove is hot sometimes is the only way we learn. Acknowledging this - does it mean we shouldn’t provide the knowledge because somone may do something stupid? I don’t believe that should be the case.

              In short: people are going to do dumb shit - but I don’t think that means we need to over engineer the world to protect them from themselves.

          Should be ok as it isn’t going that deep anyway. If it fails you get out and surface.

            Oh I know, and I’m not worried about the guy trying this in his pool

            I’m worried about the idiot who thinks this too will work for a 30 meter dive, because there is always THAT guy who knows it all

              I can see someone strapping the helmet to their head, then get a leak while 1m deep. They notice when it fills up. Panic and try to get it off, can’t. Surface, it’s still full of water because the leak is at the air entry hole and they designed it to fit snugly around the neck and it won’t drain without tipping upside down. Drowns while struggling to undo the straps holding it on

      My concern would be about lungs overpressure when going to the surface (and ears overpressure too, when going down/up, but less deadly).

        Yeah, it’s adding some risks of diving without many of the safety mechanisms or training.
