Did you know that lenses for glasses are produced from a lens grinding machine?

More importantly, did you hear about the guy who got his hand caught in one?

It really made quite the spectacle.

TIL During WW2, The Allies targeted the ball bearing factory in Germany where the Nazis made all of the bearings for the war.

They were trying to get the Nazi war machine to grind to a halt
