When you’re out in the middle of the wilderness, safety is always your primary concern. For campers and hikers, this means bringing lots of water and snacks to keep up your strength.

But what if something goes wrong and you find yourself trapped outside waiting for help to come and find you? You’re going to need fire, too, in order to stay warm and cook food.

Luckily, you don’t have to worry about rubbing sticks together! The next time you go camping or hiking, all you have to do is make sure you pack nails, copper tacks, copper wire, and… a lemon!

If you’ve ever been hiking or camping, you know that safety is always the primary concern. Having plenty of fluids and food on hand is essential, but knowing how to make a fire is perhaps equally important. Most people wouldn’t know how to start one without a lighter or book of matches, but there’s another way to do it: using a lemon!

A YouTube channel called NorthSurvival demonstrates creative ways to survive in the wilderness, including how to start a fire with a lemon. Believe it or not, all it takes are a few simple techniques to help you make it for days, or even weeks, if you ever find yourself stranded with few resources.

For this particular experiment, you’ll need a lemon (obviously), six copper clips, six zinc nails, a piece of wire, and a handful of steel wool. All these items might sound odd, but once you see how they’re rigged together, you’ll be amazed.

The first thing you’ll want to do is roll the lemon back and forth in the palm of your hands.  This helps to soften the rind and inner pulp. If the fruit is too firm, the nails and copper clips won’t be able to puncture the outer skin easily.

After you’ve rolled the lemon for a few minutes, carefully insert the copper clips in a straight line down one side of the fruit. Leave about a centimeter’s distance in between each one. Don’t push them all the way in, either.

After all six of the copper clips have been inserted about halfway, take the six zinc nails and place them into the rind so they line up with the copper clips. Make sure none of the nails are touching each other.

After the nails and clips have been inserted into the lemon, take a small bit of wire and connect the first clip diagonally with the second nail, like the photo below. The second clip connects to the third nail, and so on. This connection will help create electricity. At the end of this step, you’ll have a free-standing copper clip on one end and a free-standing sink nail on the other.

Now, take two longer pieces of wire and wrap them around the free-standing copper clip and sink nail. The sink nail will act as the negative electrical charge, and the copper clip will be the positive charge.

Finally, place the steel wool on a dry surface and add some tinder to the top. You can use any kindling that lights easily, like toilet paper or dried grass. Next, place the free ends of the wires onto the steel wool pile and watch what happens…

Who knew that you could use something as simple as a lemon to start a fire? Watch the entire video below for a thorough explanation of each step. You’ll be in shock when you see just how effective this life-saving technique is!

Five volts of power might not seem like a lot, but as you can see, it’s more than enough to get a fire going. People might look at you like you’re crazy for carrying around such random supplies, but the joke will be on them when you end up relaxing by a warm, toasty fire!
