Kinetic Theory Model

Kinetic Theory Model provides in analogue form a visual representation of molecular movement in gases.
The motor is provided with a speed control. 
Higher speeds give more extensive movements of the spheres. 
A piston, in a wide perspex tube, is vibrated by a low-voltage electric motor housed in a box supporting the tube. 
For demonstrations to larger groups illumination from the side and a black background are recommended, to highlight the spheres.
The movements of the spheres are seen to be random both in direction and extent. 
Metal spheres, simulating gas molecules, are propelled upwards in a tube by the piston's vibrations.
