About: Wimshurst Electrostatic Machine

This 1884 machine was used to generate static electricity. It could throw a constant stream of sparks up to 30 inches long and was the largest ever built by scientist and engineer, James Wimshurst. The disks rotated in opposite directions, picking up a full charge even before a single revolution was made. It was one of many such machines in the late 19th century when electrostatic generators were very popular and used for everything from scientific demonstrations and experiments, to parlor games in people’s homes.
