Safely demonstrate open and closed series circuits without any danger of electric shocks! When the tube is "turned on", the red, green, and blue lights light up and it makes an eerie fluttering tone. Activating the tube is the fun part - just touch the metal ends with both hands. Your body forms the conducting material that bridges the gap between the two metal strips and closes the circuit! 7" x 1.5".
