Light & Sound Energy Ball
Provide a safe, dramatic, hands-on demonstration of an electrical circuit.
Two exterior metal strips are the circuit terminals. Children join hands to form the circuit. When the last two children touch their free hands to the terminals, the battery-operated plastic ball lights up and beeps.
Demonstrate switching by breaking and then re-linking the circuit. Batteries included. 1½" dia. Ages 7 and up.
