1. 9v battery
2. steel wool


Learned this in boyscouts years ago. Since then I've used it millions of times and always carry it in my pack. Easily packed, and it's a cool thing to show people that don't believe.

How to do it (very simple):
Touch two prongs of battery to the steel wool.... thats it!
Easiest thing to do is gather dry kindling and wrap it around the steel wool. Bada bing bada boom... fire!
