Just touch both ends yourself or with a ring of people holding hands to create forks of lightning within the tube.

Start flashing lights and buzzing sounds in this fascinating energy stick simply by touching each end to complete a human circuit. How it works is really simple! The Energy Stick has a highly sensitive circuit that’s able to detect very small amounts of electricity that travel across your skin. Put a hand on each of the foil ends of the Energy Stick and the flashing lights and buzzing let you know that you’ve completed the circuit. Try forming a circuit with several friends. If a person takes hold on one end of the Energy Stick and a friend holds the other, simply touching hands will be enough to make a connection and light up the energy stick. No batteries required.
