This underwater breathing system does not require batteries like a hookah dive system (surface supplied air diving) and it does not require heavy scuba dive tanks.
In this video I demonstrate how to make an underwater breathing device and how this underwater breathing system works.
Homemade underwater diving or breathing systems can be dangerous.
An important diver rule is: “Don't hold your breath when you ascend.”
If you build and use this underwater breathing device and you hurt yourself, I cannot be held responsible.
