This device is named after Benjamin Franklin, although Andrew Gordon invented them around 1742. Franklin famously used them to detect approaching thunderstorms. The device consists of two bells on nonconductive mounts, and a small conductive ball hanging on a thread between them.

.By inducing a charge on the aluminum ball, the armature will be deflected by an amount proportional to the charge. This electroscope consists of a ball terminal on a metal rod, insulated fom a circular metal frame. A pair of metal leaves suspended from the rod separate when the ball terminal is electrically charged.
