This is the best way to demonstrate a circuit with kids (and adults too)! It is a great metaphor for connection in community and has even connected 20 people together!
Completely safe to touch and handle, the Energy Stick features electrodes on each end of its 7.5″ long tube. When these electrodes are touched simultaneously, long-lasting LED lights inside the tube flash and the tube makes a noise. Release one or both of the electrodes and the flashing lights and noise stop. Do it over and over again… it works every time!
