Examines some fun science experiments. Crash, boom, bang: destroy! There's nothing children love more than the satisfying smashing and bashing of things being demolished. They always do it for sheer amusement; now they can do it in the name of science. And they'll enjoy it so much that they won't even think they're learning physics as they're wrecking stuff. Just imagine the expression on kids' faces as they watch a microwaved marshmallow grow bigger ... and bigger: up to four times its size. Will it blow up? Think of the delight as they power cardboard racecars with ordinary balloons or launch homemade rockets. All the scientific terms are explained in language that children will both understand and appreciate--and the safety precautions make sure the science stays fun and worry-free.
