Cartesian Diver is supplied with hollow glass diver, with a 10” x 1.5” glass
cylinder, a rubber sheet and rubber band. Fill the cylinder with water,
drop in the diver so he floats, fasten the sheet totally across the top and
then gently depress the sheet. The diver will dive, his speed depending
upon the pressure you place on the sheet, release the sheet and the
diver returns to the surface. The diver’s behaviour illustrates the uniform
transmission of pressure in all directions, the compressibility of gases
and Archimedes Principle.
