Ronald Stavig trys out a Plasma Sphere.
Plasma balls are glass balls that contain neon gas.
Within the outer ball is an inner ball filled with metal. At the base of the ball there is a device that produces high frequency magnetic waves. When the knocked off gas electrons recombine, they give off color. When you touch the ball, you allow the electrons to recombine around your finger. You may feel a slight tinngling sensation caused by the vibrations fo the glass as the recombined electrons strike the surface of the sphere.
