Just for kicks, Australian auto system manufacturer AXT Turbo put a fidget spinner in a vice and blasted it with an air compressor:
We were playing around with the fidget spinner after work, seeing how fast and what the structural integrity of the unit is. We first started with finger on it until it got a little hot. Then we put in in a vice. After it let go, we calculated it was turning 50000 plus RPM.
