Light: This is a USB plasma ball. (6/365, niftyken)


Make that a USB plasma ball staring at itself in the mirror. These things are so mesmerizing with their constantly changing motion. How does this clear orb, filled with a low pressure mixture of gases and driven by high frequency alternating current at high voltage generate bolts of light which extend from the inner electrode to the outer glass container?
