Two pith balls are suspended by a silk threads from a non-conductive stand. When they are not charged, they hang down loosely and touch each other (Photo 1). When the pith balls are charged by touching a charged object, they have the same polarity charge and repel each other (Photo 2). The distance between the balls is determined by the amount of the charge. Photo 1 of 2.
