I am interested in tools and machines, encountered so much moral paranoia, when learning about bearings.

I guess, the do gooders were eventually going to ruin anything popular. On Youtube, the wi-fi enabled fidget spinners start fires. They are shown cutting through skin and breaking bones, at 1,000mph. They cause fights, so were banned from schools, resulting in kids being read their Miranda rights.
Warn the town.
(The instructive videos were possibly more dangerous. Someone recycles brass from spent bullet casings, in a homemade furnace, then uses liquefied gas to shrink and mount the bearings.)
