Experiment with a wedge.

You will need: ~ 2 books ~ a table ~ A friend ~ a wedge (any size) Stack the 2 books on the table. The friend should hold the back side of the books so they don't slide. Push the wedge in halfway. Look at how the wedge pushes the the books away from each other. Push the wedge in more. As it goes in, the top book goes up more. The force to push the wedge in is less than the force needed to lift the books.
