Product Description

Super Handy! It applies to any USB Interface
A plasma ball is a vacuumed glass ball with inert gasses inside. An alternating current, at relatively high voltages, are pumped into the sphere via an electrode in the center. This energy causes electrons to be stripped from the gasses. The arcs will congregate to and follow your touch while your finger touching the glass. It can expand a USB port into 4 which means it is combination of fun and usefulness. Of course, you can also turn off the light if you are tired of it.
