Has anyone found any other uses for ball bearings than just for tripping people? Especially as 1000 ball bearings seem a bit excessive to cover such a small area. How big are those balls anyway?
Edit: I should read D&Ds definition of the word "ball bearing" first instead of assuming they mean the modern one.
