Van De Graaf Bank
The Van de Graaff generator is attached to a bench so that the bench becomes statically charged. Everyone who sits on such a bench becomes statically charged, too – much like running your hand along the toroid of a classical Van de Graaff generator. This device allows visitors playfully to explore the principles of electrical fields. Small particles in the immediate surrounding such as confetti will begin to dance through the air as if by magic. The exhibit is installed with an outgoing circuit that allows visitors to statically discharge upon exiting the installation.
