Ten Minutes: Wind
Wind blows. Sure, it's all fun and games when you're out flying a kite, but, like all elements, it has a dark side. In fact, it makes all those other elements more difficult to deal with. Rain will pelt you harder and a cold day will become even colder – able to pierce through three layers of jackets and your skin. Even on a warm day, wind can toss trash right in your face. It has a horrible sense of humor. Fire may have the most dangerous rap sheet, but wind is what makes it unmanageable. They're accomplices, after all. There's no fire without air and that is easily more menacing because that means it’s everywhere you are. I'm talking classic elements, of course. If we take the periodic table into account, I may switch my answer to arsenic.
