You can make the Sci-Fi Tube light up and make sounds simply by touching the silver-wrapped electrodes on each end at the saem time. It might sound like science fictions, but it’s true! The human body conducts electricity, and by touching the child-safe electrodes 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, the circuit will power your Sci-Fi Tube! Excellent for conductivity demonstrations in the classroom, or fun experimentation at home!
