Discover the secrets of the human body with the newest beautiful, educational, and fun title in the Shine-A-Light series.
Hold a light behind the pages to see muscles flex as a football is kicked, watch as food travels through the digestive system, and take a peek at the skeleton holding you upright.
By holding a light behind each page, children can see the details behind the surface. The clever see-through reading technique creates an experience of interactive learning, showing both the surface and what is hidden underneath at the same time.
So much fun & learning(!) 
Cute book!
