Snails don’t like salt. “When you pour salt on a snail (or slug) the water is very rapidly pulled out of the cells of the snail’s body by a process called osmosis. As it dries out, the snail’s body produces a slimy substance to protect itself. The bubbling comes from the slime and air being forced out of the snail’s body as it shrivels up.” – UCSB.
