UFO Energy Ball

It may look like a simple ball with two pieces of metal, but when both pieces are touched, the ball lights up.

This UFO Energy Ball magically lights up and makes a sound when touched. It is an excellent demonstrator of closed and open circuits.

Complete the circuit by yourself or with a group of people to experiment with the basic principles of conductivity. Safe for ages 5 and up.

Diameter:
