The poop factory

Take a tour of the special poo factory and find out just how important all its parts are in processing everything you eat. And thanks to the clear illustrations, you'll know exactly what happens before you go for a "number two". We don't talk about this factory very much, yet we all carry it inside us, and when it isn't working as it should, we can't think of anything else. Together with the professor's children, we'll take a tour of this factory—from the entrance gate in the mouth, through the acid bath in the stomach, to a rollercoaster ride in the small and large intestines, all the way to the top-secret destination.
