Did you know you can use a piece Steel Wool and a 9 volt Battery to start a fire? Simply rub the battery terminals on the steel wool and then use it to light your tinder.
Check out this video to see how it’s done.
A word of caution!!! If you want to be prepared, stock up on lighters. They’re the most reliable way to start a fire in almost any survival situation. I do not recommend carrying steel wool and a 9 volt battery in your survival kit. I would only use this method if I had these items at home already and I wanted to conserve lighter fluid.
