Touch metal strips of this electric sensor ball to complete circuit – lights flash, sounds buzz!
This ball may look like an ordinary ping-pong ball but touch it and you’ll see it’s anything but a normal plastic ball. This electric sensor ball ball lets you conduct electricity with your hands! The Sensor Ball allows you to experience the science of electricity and circuits. Just place one finger on each of the two silver bars at the bottom of the ball and voila! You have just closed the circuit, allowing electricity to flow from one finger, through the ball, through your other finger and your body.
