USB Powered Plasma Ball that will surely impress your colleagues!
Plasma is the fourth state of matter - as the ball becomes energised, the gases inside light up and turn into plasma. By touching the outside of the ball, you provide a path for the energy to escape, so you can produce amazing effects.
[That's what the advertising says, but they don't know a lot of Physics. I simple terms, the effect is due to the ionising of the He/Ne gas in the glass by a relatively high voltage electric field, which is altered somewhat by hands placed on the glass]
System requirements:
• Windows XP or Mac OS X • USB 1.1 port
Measures 130(H) x 100(W)mm
