Stuff you should know! : when you tweet on twitter? When you recycle your soda can? When you charge your iPad?

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.
