4M MICRO ROCKET is a mini reusable rocket. Just add vinegar and baking soda to this rocket and watch it blast off. It can be used over and over again.
How does the rocket work ?
Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate (NaHCO3) and vinegar is an acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide. You can make your own vinegar and baking soda bottle rocket!
The chemical reaction actually occurs in two steps. First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid. Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas.
The carbon dioxide escapes the solution as bubbles. The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it… A dilute sodium acetate solution remains after the reaction.
