Make your own CO2-powered “Message in a Bottle" Rocket just like construction queen, Camryn Coyle. Shh ... there's a hidden chamber so you can blast a top secret message sky high! You can do it again and again just using ingredients from your own kitchen, like baking soda and vinegar. Picking Up S.T.E.A.M. The vinegar (an acid) and baking soda (a base) react to create carbon dioxide gas. This gas causes air pressure to build in the body of the rocket. When there is enough pressure, the contents are forced downward, propelling the rocket upward. That’s Newton’s Third Law of Motion at work -- for every action, there is an equal and opposite reaction! Product includes: • All the pieces needed to build your rocket, including rocket top, body with secret message compartment, chamber, base and fins (household ingredients not included) • 2 papers to write secret notes for friends • 2 sticker sheets and 2 rocket-shaped chalk markers to decorate • Ages: 8+ years
