Boyle's Law Diving Science #2

Dedicated to Miss Gidds :)
It is one thing to tell new divers about Boyle's Law but it is another thing altogether to show them. In this video we want to show you what happens to the lungs, and air contained in therein, when a freediver descends to 14m.

We sunked 2 empty clear glass bottles.
Left side bottle cork is open
Right side bottle mounted yellow baloon and wraped with red tape to fix baloon to a bottle neck

Free divers on videos
Dive 1 and 2 Nik Vatin
Dive 3 Scott Swanson
