Pith Balls on Stand
A pith ball is a very small, lightweight object that picks up electric charge quite well. A charged pith ball works well to show the Coulomb force between two charged objects. If a glass rod is rubbed with silk, the silk rubs some electrons off the rod. The rod thus becomes positively charged.
