  Iron lung diving snorkel setup. Allows you to overcome the pressure and use a 15m long snorkel!

  And you accidentally set it to the wrong depth and blow up your lungs.

      Overpressure, 10m deep is roughly double the pressure at sea level.

        But wouldn’t the excess pressure and air just go out the bottom of the helmet? it’s open to the water below, similar to shallow-water helmets, which are used by untrained tourists.
