My Crazy Inventions Sketchbook
Do you have some crazy inventions up your sleeve?! This book is jam-packed with amazing drawings showing 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? There is plenty of inspiration to get kids' minds going, and plenty of room to add their own crazy inventions to the mix. Includes a patent certificate for their very own crazy invention!
