Activate this tube’s sound and light effects using only touch with this human-powered tube to demonstrate human conductivity, circuits, and electrodes!
The human body conducts electricity, and by touching the child-safe electrodes on each end simultaneously, you complete the circuit necessary to activate the lights and sound. Try it with your friends! Make a circuit of 2, 3, or even 50 people! As long as you are touching hand-to-hand or at least skin-to-skin, you’ll complete the circuit!
