I need a small container to keep salt in, on the off chance that I encounter a leech firsthand. Or firstleg. Are there any small containers that are waterproof enough to keep salt from clumping? I'd only need a couple tablespoons or so.
I've actually needed this before. I found this poor turtle with a bunch of leeches on it, and I figured I'd give it a chance to not die of bloodloss from having a dozen little nasties on it. I had some salt in my backpack for just this purpose, and after a few huge pinches of salt, one leech-free turtle was released.
