Deadly (not) Fidget Spinner for US Quarters

A somewhat dangerous fidget spinner that uses 12 US quarters as weights. It has ridges to bite and launch any thing it comes in contact with (yes, I stole the idea from Angus). I have gotten it to spin for 2 minutes with a cheap metal bearing off amazon. If the bearing are greased you need to remove the shields then drench the balls with WD-40. Let it soak for about a minute than spray all the grease out with an air compressor. (Optional) Get some silicone lubricant, the kind I got has some sort of ceramic teflon (The can says Cereflon) and spray in the bearing. Give it a good spin with the air compressor and you're good! It is very heavy and has a lot of inertia.
