Unique Gadgets & Toys 8" Plasma Globe offers you a safe, fascinating way to demonstrate how lightning works as well as explain the concepts of potential differences and electron orbital jumping. A small Tesla coil produces a large potential difference between it and the glass of the surrounding globe, similar to a cloud and its potential difference with the ground. This potential difference uses inert gases inside the globe to complete a circuit and release its potential to the outer glass, just as a cloud releases its potential to the ground. The result? Bright, harmless, violet lightning bolts that respond to touch and sound. Approximate size is 12" tall with a 8" ball and 5"x5" base. A.C adapter is included. Not recommended for children under 8 years.
