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.
