This is a popular accessory for electrostatic demonstrations. An insulating printed circuit board carries a metallic conduction path with six breaks and a binding post at each end. When connected to an operating electrostatic generator, simultaneous sparks occur in each of the breaks as charge flows between the poles of the generator. Will work with Wimshurst or Van de Graff generators.
