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

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


5 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 saving everyone’s life.
