Klutz Book of Inventions

Created by the same brains that brought you The Encyclopedia of Immaturity, it’s a 200-page catalog of never-before-seen contraptions that are equal parts brilliant, useful, and ridiculous. None of them exist as actual products, but in a better world, a funnier world, they would all be household essentials. A helium-filled hide-a-bed (hop out and it hides on the ceiling), a tricycle-lawnmower combo (puts wasted play energy to work), and so much more.
