This book challenges the notion that necessity is the mother of invention. One hundred and seven inventions--from diapers for pet birds to a motorized, rotating ice cream cone--are presented with color photographs, schematic drawings, and interviews with each inventor that reveal the inspiration for their creation. The book details the amount of capital it took to get the invention from the garage to the marketplace and how much each device has earned. The book also includes gadgets that will make you wonder why you didn't think of that; an alarm clock that rolls away before you can hit the snooze button and a device that imposes limits on a child's computer and television use demonstrate the ingenuity of man and capture the essence of the American entrepreneurial spirit. 9 1/2" H x 9 1/2" W.
