Light Leaper Accessory, 1 Each

The Light Leaper Accessory by United Scientific is an electrostatics demonstration board with a metallic conduction path broken by six gaps between two binding posts. Connected to an operating electric Van de Graaff generator, it produces six simultaneous sparks as charge flows between the generator poles. Physics teachers use it to make spark discharge and continuous charge flow visible to a whole class. It is not compatible with Wimshurst machines or hand-crank generators.
