All you need to get this rocket flying is a little baking soda and vinegar. Upon mixing the two ingredients, the ensuing chemical reaction forms carbon dioxide, which builds up in the rocket cavity until it cannot hold any more. The accumulated gas will escape from the bottom of the rocket, resulting in a thrust which will propel your rocket up to 50 feet in the air.

Travelsmith Cosmic Rocket Kit

A Right whale standing on its tail, the Hollywood sign, and that giant, radiated woman who attacked Los Angeles in 1958—those would all be 50-foot-tall things that the Travelsmith Cosmic Rocket can soar over! Powered by thrust from escaping carbon-dioxide bubbles formed when you mix vinegar and baking soda, this beginner's rocket is six inches long and comes with its own launching pad.
