I’m going to let you in on a little secret that’s pretty incredible. You’ll want to keep this in your file, labeled ‘Uncle Zack’s Tidbits of Unnecessary Things to Know.’ (You are keeping up your file, aren’t you? There will be additions as we go along, and perhaps a Pop Quiz one of these days.) Stand confounded: as amazing as it may be, using your hands alone, it is impossible to fold any piece of paper in half more than seven times, no matter how big or small a piece of paper you start out with. (It’s okay; don’t worry. I won’t go on without you. I know you have to stop reading and try this out. I’ll wait here while you go fold the newspaper, that scrap of paper laying next to your computer, and the snail-mail letter that just came from your dear old Auntie Doris.) What you hear now are the sounds of my fingers drumming my desk top while I wait.
