Glass Cartesian divers

A Cartesian diver is a scientific novelty. If you place it in a plastic bottle full of water and screw on the top, as you squeeze on the bottle the diver sinks and rises on your command. Modern versions of this novelty can still be purchased, although they are likely to be made out of plastic.
