What is scuba diving and how does it work?
A scuba includes metal tanks which hold compressed air (or a special mix of breathing gases), a regulator to reduce the tank air pressure to breathable air, and a hose that carries the breathable air into the diver’s mouth. When a diver exhales, air is released into the water and creates little bubbles.
