There are many options to light a fire without the help of matches, lighters and combustible substances. The next method is not entirely extreme, but quite unusual – it deserves to be known about it. So, you need a lemon or any other citrus, which will serve as a source of electricity, wires, zinc and copper nails, material for ignition (in this case, wipes). Having placed the nails in the lemon, they need to be connected in a certain way with a wire – this will create a working battery of copper and zinc electrodes. Well, and then, it remains only to get fire, as shown in the video.
