Build Your Own Chain Reaction Machines: How to Make Crazy Contraptions Using Everyday Stuff--Creative Kid-Powered Projects!
This hands-on science and engineering guide teaches children how to design and build thirteen wacky, Rube Goldberg-inspired chain-reaction machines. Using basic household items like cardboard, string, and tape, young inventors learn the mechanics behind low-tech gadgets. The illustrated, step-by-step instructions guide readers through constructing practical room additions like door knockers and light switchers, helpful household devices like toothpaste squeezers and soap dispensers, and entertaining novelties like marble launchers and balloon poppers. Alongside each creative project, educational sidebars explain the physics principles at work, providing troubleshooting tips and design insights to help builders understand mechanical engineering and physics concepts.
