If you need to entertain your holiday guests, especially those with a competitive streak, and you have a couple of old phone books laying around, Stephen Fry and his QI guests are here to teach you a simple and inexpensive party trick you can use on them while simultaneously teaching them a simple lesson on the physics of friction.
I cannot be held responsible for any objects that get broken in the process :)
