The Sensor Stick lets you experience first hand the science of electricity and circuits. Just place one hand on the top silver bar and the other hand at the bottom and voila the long-lasting LED lights flash while the buzzer buzzes! You’ve just closed the circuit, allowing electricity to flow from one hand, thru the tube, thru your other hand and your body. Yes, you are a human circuit! Remove one hand and you’ve opened the circuit and the flow of electricity stops. Repeat, repeat, repeat. The fun goes on and on! Learn about electricity, circuits, conductors, electrons and more! Ages 6+
