Turn your body into a human conductor of electricity! The Giant Energy Stick helps children learn about electricity as it comes to life in the palm of their hands. Comes with an instruction card for teaching young scientists about open and closed circuits, conductors and insulators. With electrodes on each end of the stick, children simply place one hand on each end to complete the circuit, sparking sound and fun flashing lights. Have several students hold hands to further demonstrate the concept of circuits. Test the conductivity of different objects by adding them in the middle of the student chain. For ages 4 and up.
