Vividly illustrate electrical charges.
- Easy to set up design
- Works with Wimshurst or Van de Graff generators
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.
