Somehow, you've found yourself deep in the woods, and a storm is coming. It's dusk, the rain has started, and you know it's going to get a lot darker and a lot colder. So you and your companions decide to make a fire. You've seen other people do it. How hard could it be? You pile some sticks and logs together, throw a match on them, and watch a tiny flame catch, smolder, and disappear. Watching the tiny wisps of smoke fade away after a few more false starts, you come to understand the popularity of lighter fluid.
