A Cartesian Diver is a closed system used to demonstrate Archimedes’ Principle. Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

Cartesian divers are made with an air bubble, which causes them to just float when placed in water. In a sealed bottle of water, the Cartesian diver will just float at the surface. When the bottle is squeezed the pressure inside goes up and the air bubble gets smaller. As the bubble is compressed the diver fills with water causing it to lose buoyancy and sink.

Releasing the pressure causes the bubble to expand again pushing out water and allowing the diver to float again.
