- This UFO ball lights-up and makes an eerie alien sound when touched or held in your hand.
- When the two electrodes are touched simultaneously, the device flashes and makes a pleasing warbling sound.
- The Energy Ball utilizes a field effect transistor so even the slightest conduction between the two electrodes activates the Sphere.
- The Energy ball is completely self-contained and requires no additional batteries or energy source. It is often used to demonstate closed and open circuits by having two students each touch a different electrode and then activate the device by holding hands. Ball is 1.5in diameter
