Eccentric Contraptions: And Amazing Gadgets, Gizmos and Thingamabobs

Actually I bought this book as a gift to my brother. After flipping through the pages, I decided to read it cover to cover. It's a very interesting and easy read. You can finish it in a couple hours. What I did was I looked at the picture and tried to guess what the gadget was before reading the description. That added more fun to the book. If you enjoy this book, you might also like Ingenious Gadgets by the same authors. I got both books for my brother. They're good gift books.
