Summarize this article:

Smear the lip balm over a thin or non-watertight section of fabric for a quick fix. This will only be marginally and temporarily effective, but it might keep you just dry enough in a pinch. Make sure that your gear is dry and clean when you start – otherwise, the Chapstick won't be able to do much! There are a lot of zippers involved in survival gear—tents, jackets, backpacks—and these closing mechanisms are prone to getting caught on the surrounding fabric. Chapstick can act as a lubricant that might help you free the zipper from a tight spot. Use lip balm liberally, but don't expect it to fix all of your zipper woes.  As an added bonus, the waxy coating might make the zipper more water-resistant. You can also use Chapstick to lubricate screws, tools, and other things that might get stuck. Coat the blade with Chapstick by rubbing the balm directly on. This can be helpful if you're using your knife in the rain. Make sure to wipe the blade clean once you're in a dry haven. Rub Chapstick onto the lenses of your glasses, then rub them dry. This should get the glass clean, and it may also keep them from fogging up. Be aware that this tip is not officially verified; it shouldn't damage your glasses, but the thick petroleum might gunk up the lenses and make it hard to see. Try it, if you're curious, but do so with a grain of salt. Once you've used all of your Chapstick, you can use the plastic tube to store thick products like toothpaste, soap, wax, and petroleum jelly. Make sure to rinse out the compartment beforehand to remove the waxy residue. If the lid is intact, try using the container to hold basic survival gear: a fishing hook, a waterproof match, a band-aid, and some fishing line. Try hiding cash in here if you're traveling. Fold paper bills and roll them in. This can be a discreet way to keep your money close and safe.
Waterproof your shoes or gear. Use as a lubricant. Keep knives from rusting. Defog glasses. Use the empty container as storage.
