STEPDive presents: Expanding Air
This video visualizes the physics behind the need to always keep your airways open and blow bubbles as you come up from a dive. 2 flattened bottles of air are brought to the surface. One is closed off and greatly expands as it comes up. The other is open, ‘blows bubbles’ as it comes up, and keeps it shape and size.
DO SEEK OUT PROFESSIONAL INSTRUCTION! The information from this video should only be used only as a supplement to competent personal instruction from a licensed SCUBA professional.
