USB Plasma Ball
This USB Plasma Ball is an awesome decor piece and a science experiment in one.
This iconic scientific lamp was originally created by Nikola Tesla in 1894, following his experiments with high voltage currents. The plasma ball demonstrates the properties of electrical discharges, which you can control with your fingers as you touch the lamp.
The globe is a sphere that has most of its air replaced with 3 noble (inert) gases – neon, argon and xenon. A high frequency alternating current electrode is in the centre. Place your fingertips on the lamp and watch the filaments glow. It’s like creating your own personal bolt of lightning from the electrode to your finger!
