How To Start A Fire With A Battery.

A fairly simple trick.

1. Take one battery a 9V works particularly well. But you can do it with smaller sizes.

2. Get a small handful of steel wool and bridge both contacts of the battery with the steel wool.

3. At this point sparks should be appearing.

4. Place some tinder (small dried grass or very small twigs) over the top of the wool.

5. Congratulations you've discovered fire!
