Crazy Contraptions: Build Rube Goldberg Machines That Swoop, Spin, Stack, and Swivel With Hands On Engineering Activities

Illustrated by Micah Rauch. Why use a simple hand motion to wipe your mouth when you can build a machine to do it for you? Toppling dominoes, rolling marbles, racing balloon cars, springing catapults, and whizzing zip-lines are all elements used to build Rube Goldberg machines in Crazy Contraptions: Build Rube Goldberg Machines that Swoop, Spin, Stack, and Swivel with Hands-On Engineering Activities. The book introduces kids ages 9-12 (and beyond!) to the wacky machines designed by Goldberg, which were based on complicated chain reactions used to accomplish very simple, sometimes ridiculous, tasks. Young engineers are invited to invent, design, create, and play as they make their own Rube Goldberg machines using the engineering design process and lots of imagination!
