Description
A hand-held electrophorus can produce significant amounts of charge conveniently and repeatedly. It is operated by first frictionally charging a flat insulating plate called a "cake". In Volta's day, the cake was made of shellac/resin mixtures or a carnauba wax film deposited on glass. Nowadays, excellent substitutes are available. TeflonTM, though a bit expensive, is a good choice because it is an excellent insulator, charges readily, and is easy to clean and maintain.
