Color Change Plasma Ball

This is a photo of one of my Color Changing Plasma balls, these were only sold for a short time at Spencers before being discontinued. The sphere is 8 inches in diameter, filled with xenon and the glass is coated on the inside with different phosphers that glow with different colors when energized by the UV light from the plasma streams. I have 8 total, with 7 brand new in their boxes. This is a picture of the ball with my hand on top.
