Toys that move: an enterprising collection of ideas, taken chiefly from 19th-century designs, which call for relatively simple materials and. . . no batteries. The toys operate because of wind or candle power, strategically placed string or rubber bands, gravity or ""mystery power."" And although the instructions are clear enough, tinkering pays off. For dexterous adults with time on their hands, it's certain diversion. Kids will like this too, especially that mystery chapter, but younger ones will need supervision for the candle-powered toys and the soldering iron procedures. So why not try the ferris wheel or tin steamboat, kite climber of model ice schooner, or that rubber band cannon that shoots ping pong balls up to 20 feet.
