Smash It! Crash It! Launch It!

What kid doesn’t love making a mess?  Launching water balloons, dropping watermelons out of windows, crushing paper cups, catapulting grapes, parachuting eggs, and other mess-making experiments introduce youngsters to the world of desctructology (a.k.a. physics). Experiments include a list of easy-to-find materials, step-by-step instructions, and a tidy explanation of the underlying physics. Smash It! is a great introductory resource for an enrichment cluster or interest center.
