On a tiny island in the South Pacific, a super-secret laboratory has apparently disappeared! All that's left behind is a mysterious egg-like device, containing a sole book: Mad Professor. It describes wonderfully strange slimes and putties, miniature robots and transport devices, portable structures, and bizarre sound generators...Not only is Mad Professor the last trace of this mystery lab, it's also the perfect craft book for boys! Dozens of recipes and cool projects show kids of all ages how to concoct a variety of projects from widely available household ingredients. More advanced projects such as hovercrafts and countertop volcanoes are also included. With playful illustrations, Mad Professor is full of activities that are fun, icky, and educational.
