"Ever heard of a dust explosion?"

I have but it can't happen with slaked lime! Slaked lime doesn't explode. Nor does it burn, which is kinda a prerequisite for exploding.

(I suppose you can cause an explosion if you, I dunno, dump it into a vat of strong acid or something, but that's a steam explosion instead. Caused by water flash-boiled into steam by heat, not by the powder exploding.)

...Oh well, never mind, it's a REAL UMAMUSUME MANGA™!
