This exhibit consists of a small ball that sounds and lights up when its two terminals are connected by a conductor. The exhibit user places touches both terminals with his/her fingers and be surprised that the Energy Ball turns off, proving that the human body is a conductor. The user can even join hands with several people and let each person at both ends touch one of the terminals. The Energy Ball will turn on just the same.

Energy Ball is available in the "I AM a Scientist" travelling exhibit package.
