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.

 What you'll get:

  • Euler's Disk (3" diameter chrome-plated steel disk).
  • 9" Concave mirror base.
  • Nine holographic magnetic effect reflectors.
  • Instructions and Scientific explanations.


Incredible Science Fun Learning Ideas:

  • Discuss the transfer of potential energy into kinetic energy.
  • Explain how friction and vibration are key factors in slowing the disk down.
  • Examine angular momentum and gravitational pull as the key forces at work in Euler's Disk.
  • Transfer of energy into sound.
  • Predict how long it will spin before stopping.
