My Crazy Inventions Sketchbook
Andrew Rae's amazing drawings show all sorts of real inventions that seem too weird to work. How about a dog umbrella? A submarine that looks like a plane... or even a shark? A swimming machine where you don't get wet? A car wash for people? Someone has even made a device to charge your phone using a hamster. There is plenty of inspiration to get kids' minds going, plenty of room to add their own experiments, and a patent certificate for their very own crazy invention.
