ENERGY Rod turns your body into a human conductor of electricity. Watch your body conduct electricity. Touch both ends to make a human circuit. Put one hand on the top and the other on the bottom of the Energy Stick, and the flashing lights and sound maker let you know that you've completed the circuit. The Energy Stck sends out a safe electrical signal that powers the flashing lights and buzzer when you use your body to complete the circuit. Try it with a friend! Invite your friends to join the fun by holding hands and forming a large circle to test their conductivity.
