My son has checked this book out of the school library so many times he has it memorized! Great fun at home -- inexpensive science projects that really work and are fun to do --- even for Mom! The Rocket created from a 2 liter soft drink bottle and powered by water and a bicycle pump is great. Other favorites include the Archimedes' Screw that moves popcorn and the Rubber Band Powered Boat. Bright, colorful, lots of pictures, easy to understand and easy to build --even for the science challenged!

My eight year old son has become very interested in mechanical and electrical projects. We picked this book up at the library, but quickly saw that this is a "keeper." It has many projects that will help him learn how things work as he builds a working model cable car / gondola (his first major project from this book), boat locks, several types of bridges, and other fascinating projects. I suspect he'll use at least one of these for future projects in school. The book is rated for 11 years & up, but with a little help, even kids a little younger can have a lot of fun.
