Blue Jellyfish

How's this for interesting... apparently people say (and there's a phrase you should never trust) that if you're stung by a jellyfish, you should pee on the sting. But in fact, it turns out, you shouldn't. Because pee is alkaline, and what you want is something acidic to counteract the alkalinity of the sting. Which is why beaches in Townsville, Australia have bottles of vinegar available. Which is acidic, people. So - don't pee on the sting. You'll just make a mess. And look fucking weird. Take heed. Caveat emptor.
