Middle school children will have a blast building these nifty inventions, contraptions, and gadgets--some practical, some whimsical--that automate their world while they learn basic scientific principles. They will love impressing their friends and have fun using all of these easy--to--build projects, which include:
- Automatic fish feeder
- Shoe buffer
- Drink mixer
- Jewelry carousel
- Solar--powered hot dog cooker
- Fountain with lights
With the help of step--by--step explanations and fun, instructive drawings children will learn how to use recycled toys and other common household items to create each invention. And, at each turn, the book encourages them to experiment with variations on each project, leading them to come up with their own creative inventions.
