Spin the 3" patented holographic, chrome-plated, steel disk to create an amazing hypnotic display of spinning light & sound. Be mesmerized as the disc spins faster and faster and for an amazingly long time. As gravity kicks in and the disc picks up speed as it gets lower to the base, the sound of the disc gets louder and faster! Watch the dazzling effects off the mirrored base. For added effect, use it at night in a dark room with a flashlight or laser for an even more incredible display of light and sound. Euler's Disk is a great hands-on science demonstration that is related to conservation of energy, and the transfer of potential energy into kinetic energy.
