Leyden jar

Early water-filled Leyden jarLater more common type using metal foil, 1919
Discovery of the Leyden jar in Musschenbroek's lab.  The static electricity produced by the rotating glass sphere electrostatic generator was conducted by the chain through the suspended bar to the water in the glass held by assistant Andreas Cuneus. A large charge accumulated in the water and an opposite charge in Cuneus' hand on the glass.  When he touched the wire dipping in the water, he received a powerful shock.

A Leyden jar, or Leiden jar, is a device that "stores" static electricity between two electrodes on the inside and outside of a glass jar. A Leyden jar typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil. It was the original form of a capacitor (originally known as a "condenser").
