How fast can you spin ? Ever wondered how fast youre fidget spinner is really going? We can tell you - by processing the sound frequencies transmitted by youre fidget spinner and translating them into speed units. Sounds crazy ? If youre interested check out our references for more information about the process. Short: Every object creates Soundwaves when it moves (some louder some not so loud) and if we know the properties of this object and they are cirulating around a fixed point, like the arms of youre fidget spinner - we can calculculate it's speed. [Like - Frequency (rotations per second) /(arms of youre spinner * 2 * Pi * radius of the arms) cm/s ]. Any more Questions? We would love to hear them.

And for now, just sit back and enjoy. All youre need is youre mobile Phone and a Fidget Spinner. Have fun and challange youre friends.
