The Energy Ball or "UFO Ball", is a fun device for students to explore electric circuits where they become the circuit!

The Energy Ball is a light-weight, 1.5-inch ball with two small metal electrodes. When the two electrodes are touched simultaneously, the ball flashes and sounds a tone. The flashing Energy Ball utilizes a field effect transistor so even the slightest conduction between the two electrodes activates the Sphere. The Energy Ball (UFO Ball) is completely self-contained and requires no additional batteries or energy source. Demonstrate closed and open circuits, just line up your students in different "circuits" and complete the connection.
