Dream up your own amazing inventions with this fantastically creative sketchbook!

This book is packed with Andrew Rae's incredible 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? A car wash for people? Someone has even made a device to charge your cell phone using a hamster!

There is plenty of inspiration to get kids' minds going, and plenty of room to add their own awesome inventions to the mix. They can design the best beach buggy ever, create a brand-new candy to share with the world, or even draw a transformer dinosaur!

Includes a patent certificate for their very own amazing invention.
