A 2.5\" tall, hand-blown glass Cartesian diver rises and falls in a column of water as the pressure is increased and decreased. A red band around the neck of the diver helps make the diver visible during the experiment. Pressure can be increased by compressing a rubber sheet stretched over a water filled cylinder.
