(1) Put a brass ball (about 200g) on an isolated foot or stick. Attach on the ball a little sheet of copper or brass (about 1 g) by glue or screw. (2)Take a rubber bar(30 cm long, 1 cm diameter) and a rabbit's or cat's fur(about 10 cm x 10 cm). Then rub the fur on the bar and the electric loads will separate. (3) Touch the brass ball with the rubber bar, in order to transfer its load. Then rub the bar again with the fur. You can add the loads of the rubber bar on the brass ball and every time you do it, the little metal sheet will separate its loose end further from the brass ball.
