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.
