Stuff You Should Know

Stuff you should know! is the fascinating story behind the daily activities we take for granted. What exactly happens when you turn on the tap, send a message on the Internet, or telephone a friend? Have you wondered where garbage goes once you've throw it out? Or where the gas that heats your home comes from? Find the answers to these questions-and many more-as you turn the pages of this book. Special fold-out pages tell what happens when you phone for a pizza or post a letter to the other side of the world.
