This is Otto von Guericke's friction electrostatic machine replica.
Otto von Guericke made the first electrostatic generator.

* Essential Materials
1. Poly carbonate ball (Ball light cover)
2. Aluminum can
3. Conductive brush (from laser printer)

* Experiment environment
1. Humidity : 30%, temperature 23℃
2. Right side Aluminum can & human body grounded.


Otto von Guericke was a German scientist, inventor, and politician.
His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion.
