An exciting book about the chain reaction world of Rube Goldberg for middle schoolers, including 25 engineering design projects that get middle schoolers applying the laws of physics to their own inventions as they learn the scientific principles behind the actions and reactions they create. 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 machines.
