For an in-depth look at how these machines operate, please visit our Van de Graaff generator tutorial.
Lots of objects – from fluorescent light bulbs to the hair on your head— can be used with the generator to demonstrate electrostatic principles.
This tutorial shows how soap bubbles can illustrate attraction and repulsion.
