ABSTRACT:
The invention is a training device for illustrating electrostatic charges. The training device consists of a transparent tube that is capped at each end. Retained within the tube are a plurality of metallic beads. Each bead has a metal skin and a low density interior core made of plastic. The beads pickup electrostatic charges when the tube is rubbed and thereby demonstrate how these forces are generated.
