Move over Bear Grylls, someone else has found a use for urine, and not just as a refreshing beverage either.
The video below is quite possibly one of the most obscure skills you will ever learn. However, if you are stuck in a desert without any kind of gear besides a clear container and a full bladder, this is how you make a fire with urine.

There are dozens of ways to start a fire that doesn’t have to resort to peeing in a plastic wrapper. Yet, if you don’t mind getting your hands dirty and possibly being ridiculed by the rescue team, this is the urine bag fire-lighting method.
