Van de Graaf generator
Van de Graaff generator: A motorized rubber belt carries charge up to the metallic sphere. As the charge accumulates the voltage grows. Long, bright sparks will jump from the top of the Van de Graaff generator to a grounded discharge sphere. Using the strong field caused by the high voltage, hair can be made to stand on end; sharply pointed pinwheels will revolve; a string wig can be made to "float" of the top of the generator, and light can be generated from a discharge through a gas at low pressure.
