There are a lot of ways to start a fire, but I bet you didn't think using water was one of them.
When most people here the words fire and water they automatically think about using the water to put fire out.
What if there was a way to start fires with nothing more than some tinder and a plastic bag full of water?
Learn how to do that and more in the video below.
This is a really cool thing to know in a survival situation. Not many people would think of using water in a bottle, plastic bag, or anything else to magnify the suns rays.
I really wouldn't recommend using the last one with sodium. As you can see, it's rather explosive. I couldn't even imagine what it would be like carrying around sodium tablets in with your gear and it getting rained on.
This could also be a good bet with your friends. Just tell them you could start a fire with water and wait for the doubtful looks before amazing them with this cool trick.
