Cartesian Diver

Comments (0)

Produced by the Institute of Physics, this Physics to Go video shows a short demonstration that can be used to engage your students. The teacher notes include the equipment needed, tips and contain a full explanation of the physics involved.

This classic demonstration helps to get students thinking about how pressure can influence the volume, and therefore density, of a gas.

The Cartesian diver demonstration also links in with the understanding of density, floating and sinking.
