How Does it Work?

From the dust jacket:

Have you ever wondered how the telephone works, the television set, the transmission in your car, the washing machine, the vacuum cleaner, and the hundreds of other gadgets you use every day? Here is a book that explains for the layman the how's and why's of these machines that cause so many headaches and yet are indispensable to modern living.

HOW DOES IT WORK? is a valuable and practical addition to any household. Generously illustrated with simple drawings that show the mechanics of the item being discussed, it is written in terms that can be easily understood by everyone man, woman, and child. In a lucid, conversational style, the author covers more than one hundred subjects of such diversity as pots and pans, air conditioners, high fidelity, zippers, and many, many items we all use, take for granted, but seldom understand.

This book will appeal, on the one hand, to the gadget-minded hobbyist; and on the other, to the person who is completely at sea when confronted with a modern device. It will not only provide adults and teen-agers with the basic knowledge necessary to cope with the gadgets found around the house, but it will prove invaluable when called upon to answer that question so often heard from children: "How does it work?"
