Electric Plume

The electric plume has a number of colored ribbons attached to a vacuum cup.

When mounted on the dome of a Van de Graaff generator, the ribbons will slowly acquire a charge, even though they are normally thought of as insulators or non-conductors. 

As the charge builds, the ribbons will stand away from the dome and from each other.  This is a vivid demonstration showing that like charges repel one another.

Diameter of the vacuum cup is 6 cm.

Recommended for use with our 25470 Adjustable Speed Van de Graaff Generator.
