Euler’s Spinning Disk

Euler's-Spinning-Disk

There’s something soothing about giving a quarter a spin and watching it twirl around the table, but the moment never seems to last long enough. If you find a spinning disk as relaxing as I do but don’t want to strain your wrist by giving it a flick every few minutes, Euler’s Spinning Disk is the emotional balm you’ve been searching for.

The 3-inch, chrome-plated disk, made of 9 pieces of holographic foil, converts gravitational potential energy into kinetic energy. In case you don’t want to pull out your old physics books (and who wants to ever do that?), it simply means this thing will spin for a long, long time with just one flick of the wrist.

The kinetic energy, along with the foil, also creates an interesting sound that increases in pitch the longer the disk spins, and the holographic properties create a mesmerizing light show that increases the entertainment value.

  1. I’ve had one of these since middle school. I would pretend it was a talking ring from Time Machine B)
