Technische beschrijving Euler's disk
Who hasn't spun a coin on the table and watched it go faster and faster and finally come to an abrupt stop?
For those who are fascinated by such everyday physical phenomena, the Euler's disk is just the thing.
Instead of the coin on the table, you spin a disk on a mirror. Due to its heavy weight and rounded edges, the disk will spin for much longer than the coin, namely more than 2 minutes! Just like the coin, the turntable will spin faster and faster, and towards the end it even seems to vibrate until it comes to a stop.
The glittering look of the disc and the mirror create beautiful light reflections in all colors, especially when light falls on it. To modify and enhance this effect, the Eulers Disk comes with various holographic magnetic foils that are simply placed on the rotating disk and refract the light in different ways.
In addition to the light effects, the sound effects created during the rotating movements are also worth a closer listen: the friction creates tones, sounds and whirring noises that are even remotely reminiscent of spherical music.
The Eulers disk comes with detailed instructions in English.
For those who are a little more interested in the physical effects behind it: Essentially, the Eulers Disk angular momentum- and conservation of energy simulated.
The Eulers Disk is such a fascinating 'science toy' that once you set it in motion, you won't want to put it down!
