PIRA Code(s): 5A50.10 Set up time:2 minutes Operation: Place the four (two large, two small) balls on the poles in the front about 1 inch apart. Turn the crank. Physics and Science Concepts: Electrostatics Safety: Do not touch any metal portions of the generator
PIRA Code(s): 5A50.30 Set up time:10 minutes Operation: Plug in the generator. Turn on the rocker switch and adjust speed using potentiometer on the base of the Van de Graaff.
Other suggested uses include combining this with other electrostatic demonstrations found under a 5A50 heading. Also, throwing packing peanuts or taping strips of paper to the Van de Graaff are popular demonstrations. Physics and Science Concepts: Static Electricity, Friction Safety: The rod works best on dry days with the blue wig. Care should be taken when operating. Do not approach the generator while it is running. Use the grounding rod to discharge.
