About Our Spiraling Plasma Tubes:
The Spiraling Tube is a truly unique plasma effect- a tall, double-walled borosilicate tube containing a spiraling plasma discharge that continuously travels upward. The plasma light begins slowly winding around the bottom of the tube, then rises in evenly spaced spirals. The spiraling light can be manipulated by holding a magnet close to the glass, and it re-establishes its pattern when the magnet is removed.
Spiraling Tubes can be made in plain clear glass, or clear glass with the addition of multi-colored phosphors painted on the inside, which glow when activated by the moving plasma spiral.
