  The oceangate is strong with this moron.

    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 don’t know why you’re giving him that credit; he’s almost killed himself once already.

      He also burned the fuck out of his head not long ago by doing something silly.

      Still love his videos tho.

  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 helmet 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.

      Though this is awesome and cool, but I feel like we’re waiting for the first “I have no clue about physics or what I’m doing” ending up dead

    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.
