Euler’s Disk In Action

This already popular video is literally three years old, but has just had a second viral surge, amassing over 250,000 hits just this week.

The Euler’s Disk is an educational science toy that is based on the studies of the 17th century scientist, Leonard Euler. When spun, the disk lets off amazing sounds and reflections.

For a good 45 seconds, it seems like the disc will finally fall, but it somehow continues to spin, sounding more and more space-like with every moment.
