If you're ever hiking or camping in the middle of nowhere, safety should always be your No. 1 concern. You may bring plenty of water and protein bars to keep your energy up, but if you stray from marked trails and wind up lost, you could need to start a fire to stay warm.
Since nobody would ever bring matches or a lighter with them into the woods, YouTube user NorthSurvival demonstrated how to make fire with nothing more than a lemon, six copper clips, zinc coated nails, a piece of wire and some steel wool, because those are things everybody brings on a hike instead of matches or a lighter.
The first step is to soften up the lemon. Usually, telling the lemon how good-looking it is softens it up pretty good, but you may be better off rolling it in your palms while applying slight pressure.
Now you essentially have a lemon battery. To get the energy out of the lemon, you just need to attach wires to the zinc nail and copper clip on either side of the lemon. The zinc nail on the end will now act as the "minus" side of the battery, while the copper clip end is now the "plus" side. This lemon battery should now produce about 5 volts of electricity.
Five volts of electricity might not seem like much, but when both wires from the lemon touch the steel wool, it's enough to get it red hot. As the steel wool heats, it will begin igniting the kindling.
So there you have it. If you're ever lost in the woods and don't have a lighter to make fire, just be glad you brought along a lemon, copper clips, zinc nails, some wire, wire cutters, steel wool and toilet paper. It's a life saver.
