Just A Touch

Fascinating and fun. USB Plasma Ball is fascinating to watch and even more fun to play with -- just place your fingers on the glass surface and watch when colored "bolts" of glowing light follow your every move as electricity seeks a ground. Powered by your computer's USB port. 6 inches tall, base approx. 4 inches diameter.
