diving mask: https://amzn.to/48nIexo hookah scuba diving system: https://amzn.to/3GMID0y 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.
