Hollow Sphere

Static charges lie only on an outside surface, and this is the device that shows it.

Charge the sphere by touching it to the dome of a generator.

When a proof plane is touched to the outer surface, a charge will be acquired, but when it is touched to the inside surface, no charge will be transferred.

The sphere's re-entrant hole is 4 cm.

The sphere is 10 cm in diameter, and the device height is 26 cm.

Recommended for use with our 25470 Adjustable Speed Van de Graaff Generator.
