Study electricity without getting zapped! Luminglas lightning disks make a spectacular and completely safe electricity demonstration. The Plasma Globe, a small Tesla Coil, produces an alternating high voltage potential which attracts or repels free electrons, making an awesome light show! Retrace the steps of Morse and other inventors as you conduct experiments and build a device that works as a telegraph sounder, a buzzer, and an electrical relay. Snap together electronic blocks to build over 300 different electronic circuits. No wire twisting! When the two electrodes on the Energy Ball are touched simultaneously, the device flashes and makes a warbling sound.
