Demo Title: Van de Graaff - Wig and Streamers
Condition: Good
Principle: Electrostatics
Area of Study: Electricity & Magnetism
Equipment:
Van de Graff generator, wig, Kim wipe hair, cloth streamers, section of cat's fur.
Procedure:
Attach the wig to the Van de Graff generator using the Velcro. The hairs of the wig should stand up and repel each other as charge builds up on the dome. The hair may be replaced by Kim wipes or the cloth streamers for the same effect.
A section of cat's fur may be set on top of the Van de Graff if a wig or streamer is unavailable. If not taped down the cat's fur will fly off the Van de Graff.
