Charge and Carry

Charge and Carry

This site contains an activity on electrostatics. A styrofoam plate is rubbed with wool to give it a large electric charge that can be transferred to an aluminum pie pan. This electrophorus, or change carrier produces a spark that can be felt, seen, and heard. Materials needed, assembly, and an explanation of results are also provided. Also featured are directions to store up an even larger charge in a device called a Leyden jar, made from a plastic film can. This activity is part of Exploratorium's Science Snacks series.
