From the creator of the wildly popular webcomic xkcd, hilarious and informative answers to important questions you probably never thought to ask. What if I took a swim in a spent-nuclear-fuel pool? Could you build a jetpack using downward-firing machine guns? What if a Richter 15 earthquake hit New York City? Are fire tornadoes possible?
