Have you ever used a dog umbrella? What about a submarine that looks like a plane—or even a shark? My Crazy Inventions Sketchbook is jam-packed with Andrew Rae's amazing drawings showing all sorts of real inventions that seem too weird to work.

These activities will inspire the imaginations of young inventors everywhere, and there is plenty of room for kids to add their own crazy inventions to the mix. They can design the best dune buggy ever, create a brand-new sweet to share with the world, or draw their very own Transformer dinosaur. The book includes a patent certificate that congratulates children on their wacky invention.

My Crazy Inventions Sketchbook recommended for ages 6+.
