Description:
Diving Bell -Underwater exploration has fascinated us since we first started sailing
the seas. The diving bell in one form or another has allowed us to
breathe under water. Used by such notables as Alexander the Great,
Bernoulli and Pascal, it is essentially a submerged container filled
with air, the air pressure holding the water at bay. Our simplified demo
contains a bell, syringe, connecting tube and instructions. First draw
the air out with the syringe; then place the ball in water and watch it
sink. When you inject air slowly back into the ball, it rises.
