Young readers move cardboard operating levers located at the edge of each page to set 10 extreme machines in motion. One vivid color illustration shows a deep-sea submersible with its robot arm--and when kids move the lever back and forth, the arm creates the illusion of removing treasure from an ancient shipwreck. Other extreme machines include a crane with steel ball that demolishes an old building, an excavator that loads debris into a dump truck, robotic paint sprayers and lifting devices in a modern auto assembly plant, a monster earth-moving machine, and a robot vehicle exploring the surface of a distant planet. Kids learn how extreme machines do their jobs by moving control tabs. Highly realistic color illustrations are printed on board pages.
