How many bones do you have? Why do you need to eat? What happens to your ears and nose as you get older - but not your eyes?
Open up the giant fold-out skeleton, flip the flaps, pull the pop-ups, turn the wheels and peek through the 3-D glasses to find out how your body works. Discover all about your bones, organs, muscles and senses, then see how everything fits together.
It's a nerve-jangling, leg-pulling, eye-opening look at your body! Perfect for homework, projects or just for fun.
