Kids are surrounded by technology these days, but unfortunately fewer and fewer of them appear to know how their gadgets or the world around them works.This book is a good introduction, even if it is a bit lightweight.There's a mix of ordinary things like electric shavers and guitars, the somewhat exotic like fiber optics and things mostly on the drawing board like fuel-cell cars. In all, more than 90 objects, processes and technologies are described.The explanations are all essentially superficial and profusely illustrated. It's enough to get a young person interested and perhaps move them along to considering learning more about technology.Jerry
