Product Overview
With Volta’s Hailstorm apparatus used in conjunction with a Van de Graff generator, you can demonstrate Coulomb’s law qualitatively and illustrate the method of smoke control based on the electrostatic removal of solid particles from the smoke stream.
The device consists of a chamber on an insulated base with ball terminal to attract electric charge. Also supplied is a small amount of conductive coated spheres to use in the chamber. When the ball terminal is brought near an operating Van de Graaff generator, the particles will bounce rapidly. They are first attracted to the upper plate but, after touching, are violently repelled downward, where they lose their charge upon contacting the lower plate. They are then ready to be attracted back to the upper plate, and so on.
