Plasma Ball 3" USB Powered
This item is made of premium material, for durable and practical use. When you put your hand on the ball and move it across, the lights will follow your fingers and look like lightning chase your fingers as well as like little tornadoes, but it is safe. It has a nice and fascinating natural plasma arc on its own moving around. It looks like lightning coming out of the ball, and the colors are so bright, really marvelous.
