It's Pure Chemistry

For everyone who's ever wondered why having salt poured on them is bad for slugs and snails, see this detailed explanation from a chemist, on Adventures in Ethics & Science. It is a fitting celebration of National Chemistry Week.

I confess I have never actually poured salt on a slug or snail, though I have accidentally stepped on them, which is also messy. I'm rather fond of snails in the abstract, slurming along in their handsome curled shells with their little waving feelers, but I'm sure they're much less charming if they're eating the lettuce in your garden.

Mice are pretty cute too, unless they're chewing up your bread and leaving little mouse droppings in your silverware drawer.

It's all a matter of whether or not something is competing with me for food.
