I watched the show....4 fat guys in the woods.....they started a fire with 2 flat stones , a tampon, and wood/ ash/ coal/dust....it was interesting
same with a battery from your flashlight and the foil from a gum wrapper
did you know....corn chips, potato chips or anything like that, that is fried in oil will burn to help get a fire going (you need a flame for this one)
x-tra fine steel wool and a 9 v battery does great too
