Ever wanted to know how to make a fire with your cell phone? All you need is a cell phone, a brillo pad, and material for tinder. First take the battery out of your phone and find the positive and negative contacts on the bottom of it. Next tear off a chunk of the brillo pad, roll it up until you have a twisted piece about an inch long. Bend the steel wool over and touch an end to the positive and the other end to the negative contacts on the battery. That causes the steel wool to smolder--now you can light the tinder with the hot metal. Follow the steps in this video to learn how to make a fire in an emergency. If you're a backpacker, knowing how to make a fire with just what you have on you could save your life!
