Euler's Disk


We have run out of stock for this item.

The euler's disk is a chrome plated stell disk that is 1/2 inch thick and 3 inches in diameter. One edge is carefully machined to a smooth radius. Nine pieces of magnetized holographic foil make a variety of brilliant surface designs. A concave mirror base provides a setting for the disk to spin on like a coin...a coin that doesn't seem like it will ever stop.
