The carbon dioxide builds up inside the bottle until it launches into the air! Any kind will work, but white vinegar will make the least mess.

Step 4: Primer The rocket is ready to launch. you just need to put a bit of vinegar in the bottle and set the primer In the mouth of the bottle so that it does not touch the vinegar.Use the cap and the brooch for this like show on the picture.

An acid is a chemical that wants to get rid of a positively charged hydrogen atom (proton) and base wants that proton. Fill the bottle about 1/4 to 1/3 of the way with vinegar. Here's step-by-step directions to launch your own rocket: Supplies:…
This gas … To make one, read on. A popular science project is mixing baking soda and vinegar in a rocket or race car made out of a plastic water bottle. With the explosive power of baking soda and vinegar, you can launch your very own rocket! The gas is what causes bubbles and foam when the two ingredients are mixed. How does the Vinegar and Baking Soda Rocket work? When the baking soda and vinegar react, it creates a carbon dioxide gas. When we mix vinegar (HCH 3 COO) and baking soda (NaHCO 3), we get the so-called acid-base reaction.

Making a bottle rocket with baking soda and vinegar is always a fun and explosive (but safe) activity!

When the baking soda reacts with the vinegar, it forms carbon dioxide and water. Put baking soda in a time-release container.
The baking soda and vinegar will react to form carbon dioxide (a gas that has one carbon atom and two oxygen atoms), and the pressure created by the gas will force the lid off the container, launching your rocket into the air and crashing down. Here vinegar is an acid and baking soda is a base.
