Fidget Spinners are little toys in the hands of many students and kids these days. They are built around a centered bearing and weight in typically three arms. The weight in the arms helps to spin the toy with up to 600-900 RPMs, or even more (max. we measured as of today was 1.500 RPM).
Now the challenge starts – how can you improve the speed of your spinner? You could do an upgrade of the bearing from ABEC7 to ABEC9 or higher. But will it run faster?
