F23: Cartesian Diver


Purpose: To show that an increase in pressure on a fluid is uniformly distributed throughout the fluid (Pascal's Principle), and to show the                      principle of buoyancy.



Cartesian diver

Press on the diaphram covering the top of the jar to increase the pressure on the water inside the jar. This forces water into the diver and increases its density. The diver then sinks. Releasing the pressure on the diaphram allows the diver to float to the top. This demonstration is small and may be best seen using a close-up camera.
