How do you make a baking soda rocket?

Wrap the baking soda up in the kitchen roll to make a little parcel. Choose a launch site outside. It needs to be on a hard surface. When you’re ready to launch, drop the baking soda parcel into the bottle, quickly add the cork, put the rocket down and stand back!

What happens when you mix vinegar and baking soda in a bottle?

In our case, baking soda is sodium bicarbonate (a base) and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide. This makes the reaction bubble and expand, just like when you shake up a can of soda and open it!
