Who's never spun a coin on a desk and watched it as it rotates and spins faster and faster until it finally stops?

Well, those of you who can't help but be entranced by these kinds of phenomena are going to love the Eulers Disc for sure!

Instead of a simple coin on a desk, you spin a chrome-disc on a mirror face. Because of its weight and smooth, round edge, the disc will spin for far longer than a simple coin – over two minutes, in fact! And way more impressively than a coin, the disc will spin faster and faster until, near the end of its spin, it rotates so fast that it seems like it's vibrating rather than spinning.

Sounds cool? Indeed it is… But that’s not all! During the spin, the glitter patterns on the disc interact with the mirror to create beautiful light reflections in all kinds of colours. This is particularly cool when you shine sunlight or a lamp onto the disc. To modify and increase this rather funky effect, the Eulers Disc comes with several easily attachable magnetic holographic foils to refract the light in a multitude of ways.

Sounds really cool now? Well, that’s still not all! Not only does the Eulers Disc feature cool spinning and funky light effects, there are even sound effects too! When the disc spins, the friction generated creates tones, sounds and buzzing noises which will remind you of a kind of ethereal music.

A detailed and illustrated instruction manual in English is included.

For anyone interested in the physical processes behind this experiment, you might want to have a look at conservation of energyand angular momentum to understand the phenomena and properties associated with the Euler's Disc.

Warning! Be advised: The Eulers Disc is such a totally fascinating 'scientific' toy that you'll want to watch it spinning for hours... and hours… and… hours… and… well, trust us, you'll easily get lost in it!
