Kinetic Theory- vibrating ball type

The IEC Kinetic Theory apparatus simulates the behaviour of a gas. A quantity of small metal spheres are introduced into the slim vertical chamber and they rest on the rubber faced plate that forms the bottom surface of the chamber. A very light cylindrical float of styrene foam with a stiff paper underside is introduced into the tube above the spheres. A robust electric motor drives the plate up and down rapidly to violently agitate the spheres up into the chamber to simulate molecules of gas.
