This is a video of Youtuber NorthSurvival demonstrating how to start a fire with a lemon, some copper clips, zinc nails, wire, steel wool and toilet paper. So if you're ever lost in the woods with a lemon, some copper clips, zinc nails, wire, steel wool and toilet paper, you can at least relax knowing you can start a fire tonight. Fighting off the wolves is another story. Plus I heard there's an evil witch that lives nearby who needs blood for a potion. The fire thing though, you've got that covered. I mean, you did remember to pack your lemon and copper clips, right?
Keep going for the screw it, I'm just going to have to eat this squirrel raw.
Thanks to Neil, who starts fires the old fashioned way: rubbing two sticks together before giving up and using a lighter.
