Ever wanted to own your own crystal ball? Well now you can! ...well, not exactly. But with these cool Desktop Plasma Balls we definitely foresee a future involving a lot of "ohh's" and "ahh's" from passer by's as they pass you workstation or desk.
Watch their eyes light up with amazement as electricity follows your finger tips across their 3 inch globe. "How is it so?" we hear you ask – and we're glad you did!
The first plasma lamp was invented by Nikola Tesla through his experimentation with high frequency currents in an evacuated glass tube with the intent of studying high voltage phenomena. The outer orb is filled with a mixture of different gases at low pressure and driven by high frequency alternating current at high voltage, generated by a high voltage transformer. A much smaller orb situated in the centre serves as an electrode, causing plasma filaments to extend from the inner electrode to the outer glass insulator.
"In English please?" we now hear you ask. Well, basically placing your hand near the surface alters the high-frequency electric field being generated within, causing a single beam to migrate from its centre to the point of contact. Cool, eh? What's more, these desk friendly versions also react to sound, so no touching required, which makes them great for impromptu work parties!
Regardless of how it works the effect is certainly mesmerising and will offer some much needed distraction when you're feeling a bit frazzled at work. Simply add some batteries and feel the stress get zapped away. They're small enough not to take up too much space on your desk yet big enough to offer an awe-inspiring light show.
Guaranteed to turn heads, these battery-operated Desktop Plasma Balls make a perfect gift for the IT whiz, science boffin or anyone wanting to add a little spark to their lives. Order one today – we're sure you'll have a ball!
