Use an AA battery and a strip of aluminum to start a fire
We have already gone through several methods to make a fire, but it is such a vital survival skill that outdoor enthusiasts can never have too many options. Here is a way to create combustion using an AA battery and a piece of foil.
Scrape off a piece of the batteries’ cover on the negative side. Bend the aluminum strip in half and connect one end to each side of the power source. When it begins to glow, touch a piece of flint to it to start a fire.
