Collection of experiments using a Van de Graaff generator

"This is a collection of experiments using a Van de Graaff generator.

The generator uses a belt and two rollers to build up a charge in the dome on top. The electrons will jump from the dome to reach a grounded object. Since like charges repel one another, objects placed on top of the dome will become charged and then be repelled.

This is the same machine sometimes used to make someone's hair stand up in classrooms or in science centers."
