Machines (Make it Work! Science)

Rating:
Summary: What a great book! It should be back in print!
Review: 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!
