a nice illustration of the way our lungs contrats due to boye's law when we freedive. at -10m the volume of air is already reduced by 50%.

When I took scuba lessons in the late 1970s, we performed a similar demonstration in reverse. We filled a balloon on the bottom of the pool, then watched it expand and finally burst as it rose to the surface.
It was a very vivid demonstration of why divers with an air supply absolutely must never hold their breath while ascending.

nor freedivers ever accept air from a scuba diver.
