Euler’s Disk, by Toysmith

For ages 8 to 15

Euler’s Disk (Euler was a famous physicist and mathematical genius), is a wonderful gift for curious children and inquisitive teens who enjoy physics, mathematics and the exact sciences.

Euler’s Disk creates fascinating visual illusions which can be presented on a tabletop.  When spinning the holographic disk on the mirrored surface, watch and listen to what happens next:  Is the disk revolving ever slowly? Is the sound diminishing or increasing? How can you explain the events you are hearing and seeing?  Beyond scientific exploration, the disk is also a spellbinding audio and visual experience.

  • Dimensions: 5 x 9.5 x 10 inches.
  • Suitable for ages 8 to 15.
  • Includes: A chrome plated iron disk and a mirrored tray.
  • Manufacturer’s warning: It is forbidden for children under 3 years old to play with the disk since it contains small pieces which can be hazardous.
