Euler's Disk - The Disk that Keeps Spinning for Minutes

This 3” diameter chrome-plated steel disk creates a hypnotic display of light and sound as it rotates. Spin the disk and watch as it counterintuitively increases in speed on its mirrored platform and produces wild holographic images. Spinning for far longer than most will imagine possible, the disk audibly builds to an out-of-this-world crescendo before coming to an abrupt halt. Funky physics at its finest!

Makes for an incredible desk toy for the office or an amazing demonstration for the classroom. Try shining a flashlight on it when spoiling in a dark room for even more incredible effects.

Includes 3” Euler’s Disk, 9” concave mirror base and 9 pieces of magnetized holographic foil. For ages 8+.
