I searched but did not see a post about this. I am sure most here already know this, but for the benefit of those that do not, here you go.
- Stretch out the Steel Wool. You want it to be about 6 inches long and a ½ inch wide.
- Rub the battery on the steel wool. Hold the steel wool in one hand and the battery in the other. Any battery will do, but 9 volt batteries work best. Rub the side of the battery with the “contacts” on the wool. The wool will begin to glow and burn. Gently blow on it.
- Transfer the burning wool to your tinder nest. The wool’s flame will extinguish quickly, so don’t waste any time. (text used from http://www.pithole.com/FIRESTARTING.htm)
