Discovery Mindblown - Action Circuitry Floating Ball Experiment Set

FASCINATING FACTS: An electric circuit is like a racetrack made of conductors that electrons can speed through. A battery or other power source provides a device such as a light bulb, computer or refrigerator with electrons, and their charge is converted in useful ways to make the device work. A conductor has to travel from the power source to the device and back again so the electrons can complete their cycle!
