This is a short video clip from the episode of MythBusters on the Discovery Channel. In this episode they tried to bust the myth that it is impossible to pull two interleaved phone books apart. This is a demonstration of friction. It would be a great video to show at the beginning of the study of friction to grab the student’s attention and get them interested and thinking. It would probably generate many student questions that could lead into the explanation of friction.
