Have you ever wondered about the history of things like who invented the toilet? If so, this book is for you. It tells the stories behind some inventions that we use everyday. There is a quite humorous picture of a chamber pot being emptied out the window onto an unfortunate man! Did you know that Alexander Graham Bell taught deaf people to speak? The chapter on telephones discusses this, and other interesting facts about the inventor of the telephone, and how he thought up the whole concept of the telephone. Other inventions, such as frozen food, and the removable razor blade, are also discussed. This book is part of the Usborne Young Reading series.
