Gr 4-8- This edition follows the format of Cool Stuff and How It Works (DK, 2005), with no duplication and with eye-catching spreads devoted to cutting-edge products and inventions. More than 100 entries present a wide variety of topics with high child appeal, from robot cars to high-tech toilets. Some explain the workings of products popular with kids, such as Lego Mindstorm™. Others, such as the "vomit comet" used in astronaut training, are less familiar, but equally intriguing, and some look ahead to likely developments that don't yet exist, such as a "silent flight" aircraft that "could be a reality by 2030." Beyond the "cool" factor, many of these new technologies also benefit people and the environment in powerful ways that are noted throughout. Full but uncluttered layouts mix photos, text boxes, diagrams, and captions to highlight key elements. Contextual background is occasionally sparse; the article on the ULTra taxi®, for instance, provides excellent photos and describes the features of the vehicle, but does not mention where or when it might be used. For the most part, though, readers should have an easy time understanding the basics of what each item does, how it is used, and how it works. Along with up-to-date scientific information on high-interest topics, this title has very strong browsing appeal and great booktalk potential.-Steven Engelfried, Multnomah County Library, OR Copyright 2008 Reed Business Information.
