Can you give a hypothesis for baking soda volcano?

If an acid and a base are mixed together, a chemical reaction will occur, resulting in the formation of a gas. This gas will cause a baking soda volcano to erupt.

Explanation:

Baking soda (sodium bicarbonate) is a base. When it is mixed with an acid, such as vinegar, a chemical reaction occurs. This reaction produces carbon dioxide gas which causes the baking soda volcano to erupt.
