The Totally Irresponsible Science Kit by Sean Connolly
Included is a fully illustrated 72-page book with step-by-step instructions for the 18 experiments, including notes on how much time each experiment takes, the necessary materials, warnings when applicable - these are irresponsible experiments, after all - and the scientific excuse to do the experiment. Sure, it's a blast to send up a Soda Bottle Rocket, but it's also worth doing because it illustrates Newton's Third Law of Motion. And that messy and seemingly risky combination of ooze and electricity in the Static Electricity Slime? It demonstrates a fourth form of matter beyond solid, liquid, and gas - a colloid. Packaged inside are four helpful instruments for young scientists: a lateral split-orb measuring spoon, a vacuumatic test tube, a matter-retaining measuring cup, and photon-refracting goggles. So go ahead: Encase a younger sibling in a giant soap bubble. Drop Mentos into a bottle of diet soda and stand back as a geyser erupts. Shoot a bolt of lightning from your fingertip. Any curious kid would be irresponsible not to try these experiments.
