The Sensor Stick lets you experience first hand the science of electricity and circuits. Use your hands and the Sensor Stick to open and close your human circuit.
Long-lasting LED lights flash and a buzzer buzzes when the circuit is closed; open the circuit and the electricity stops! Learn about electricity, circuits, conductors, electrons, and more!
Just place hand on the top silver bar and the other hand at the bottom and voila! Lights flash and buzzer sounds to indicate you’ve just closed the circuit, allowing electricity to flow from one hand, through the tube, through the other hand and your body.
You are a human circuit! Remove one hand and you’ve opened the circuit and the flow of electricity stops.
