Fire
Start a fire with a battery and steel wool
A 9-volt battery and a puff of steel wool make a sparkless, windproof fire starter that works in the rain.
The Outsider — Fire with Steel Wool & 9V Battery
Step-by-step
Pull a small wad of fine steel wool (grade 000 or 0000) into a loose, airy ball about the size of a walnut.
Set the wool on a bed of dry tinder, birch bark, or fine grass.
Touch both battery terminals to the wool at the same time.
The wool will glow and burn from the inside out — blow gently to spread the heat into the tinder.
Feed kindling as soon as flames appear.
Warning: Keep the battery and steel wool separated in your pack. Accidental contact can start a fire inside your bag.
