Part of the appeal of this book must surely relate to how universal is the desire to invent something that will change the world. Most of us have probably had a glimmer or two of how we might make that happen but never set our ideas down on paper. Well, the folks whose inventions are highlighted in this book did just that. In some cases, the ideas never went further than paper while in others, the inventor created the product, but it never went anywhere. Thus, there are examples of screeching doll, a house made from concrete, devices that can enable babies to mop the floor as they crawl, and my personal favorite--a bed attached to an alarm clock that would thrust its inhabitant onto the floor if he/she remains in bed once the alarm sounds. The illustration-filled book even highlights many of the failed inventions of Thomas Edison, much better known for his successes. Not only is there a subject index but also an index of inventors for quick reference. Who knows when one of these seemingly wacky ideas might become popular and change the way we live? The odd examples in this well-written book serve as starting points that just might inspire future inventors to come up with their own ideas.
