Give the disk a spin and observe the hypnotic display of light and continually changing sound. The disk seems to spin forever, rotating and precessing as it slowly transforms gravitational potential energy into kinetic energy. The concave mirror base provides an ideal reflective surface to see the visual effects. Amazing to use in a darkened room with a flashlight or laser. Includes magnetic holographic film. 7.5 cm dia. disk, 20 cm dia. mirror.
