The Famous Plasma Ball, 7"
The 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. The height of the product is 10.2". The globe is 7" diameter and the base is 4" in width.
