Euler’s Disc

What would happen if you spin a (near) perfect disc on a (near) flat surface? This is a curious question studied first by Leonhard Euler during the 18th century. When observed, the behavior of the disc feels almost paradoxical. Its speed is seemingly increasing more and more as time passes by. The sound produced by the disc is also very unusual, especially at the end of the spin when its frequency gets very high. Now add to all of this some cool visual effects, and suddenly a serious scientific experiment transforms into an interesting gadget, both for children and adults. Euler’s Disc may not be an item you will spend too much time with overall, but something you will surely take for a spin once in a while. It is highly recommended, both for its educational value and fun factor.
