Fidget spinners are not rated for .50 cal (VIDEO)

The VSO Gun Channel got curious to see if a fidget spinner had the ballistic guts needed to bring out the best in a .50 caliber BMG incendiary round.

Using 640-grain Freedom Munitions APIs launched from an ArmaLite AR-50, they for sure bring the heat, but it does take a couple of tries before they get a nice “poof”.

Yet somehow, it still spins….what do they make these things out from?
