What you need
- A copy of Marvin and Milo’s Adventures in Science (available from bookshops and online retailers)

- Hold the book and the paper horizontally and drop both at the same time. Notice which one hits the ground first.
- Now put the piece of paper flat against the bottom side of the book and drop them together. What happens?

Results and Explanation
Air resistance means that when dropped separately, the book and paper hit the ground at different times. But when they are dropped together, the larger book sweeps the air out of the way and the two fall at the same rate.
