Make a fire with junk food
So you’re a geek… You’re probably not big on camping. But if you were to camp, you’d probably have some soda or some beer and a chocolate bar for smores. At least if you are a stereotypical geek that drinks a lot of coke and eats a lot of chocolate.
Anyway… you’ll need a fire if you’re camping, to cook your food and keep the level 55 elite bears away. You could rub some sticks together like Tom Hanks in that movie with the volleyball, or just rub some chocolate or toothpaste on the bottom of a soda/beer can to polish it into a mirror, then use that to focus light on tinder and start your fire.
