Lost in the woods with a cell phone that is out of service and no matches? You will soon have life saving fire!
No matter how prepared we may be with our multiple survival kits and bug out bags, there may be a need for fire and we only have what is in our pockets. Our cell phones go everywhere with us. They may not work everywhere, especially in the deep woods but they can still save your life even if you cannot call search and rescue. How?
So, if you take the battery off the cell phone and short out the positive and negative leads with something metal, like a Brillo pad or steel wool, then presto, you can make a spark.
Many other metallic materials may work in a pinch. This material should begin to smolder, and if you catch the spark and add it to a tinder bundle, you might just have a fire!
Its a great trick to know no matter where you may be.
