The Klutz Book of Inventions, 7.5" Length x 1" Width x 9" Height , Black

With an all-star team from Klutz and IDEO, we generated 162 never-before-seen contraptions that are brilliant, useful, and ridiculous, from a helium-filled hide-a-bed (hop out of bed and it hides on the ceiling) to a tricycle-lawnmower combo (puts wasted play energy to work) and so much more.
