You may have heard the old wives’ tale that peeing on a jellyfish sting alleviates the pain. This in reality, is a falsity; urine may actually aggravate jellyfish venom, inducing more pain.
However, here’s a trick from King of Random’s YouTube channel that really does put your pee to good use. If you’re ever stuck in the wilderness and you need to start a fire, you can use urine to create one. All you need is an empty water bottle (to pee in), some plastic wrap, some rocks, dry grass, and the sun.
