Every fact you ever wanted to know! Do you love trivia? Do you have a burning question? Then ask me one. Go on, anything you like. Why should you open me up, for instance? Because I'm stuffed with trivia, facts, fun, and incredible info on just about everything you can think of. What's the most dangerous spider? How much would you weigh if you lived on Venus? Where can you post letters underwater? I'll also tell you how to split an atom, assemble an orchestra, and find out what happens when astronauts fart in their spacesuits. You see, you really can ask me anything.
