Van de Graaff Bench
A Van de Graaff generator is mounted to charge an electrically insulated hanging bench. Anyone who sits down on this bench (analogous to laying hands on the toroid of the classic VdG) is automatically electrically charged. Playfully and with a lot of fun the electric field can be discovered. For example, confetti that visitors hold in their hands can rise into the air as if by magic.
The exhibit is staged with an entrance and exit. At the exit, there is a device for safely discharging the person.
