The mixture of the baking soda and vinegar forms a gas that raises up and out of the volcano.

We use baking soda in cooking, such as baking cakes and cookies. The baking soda makes baked goods rise because the bubbles burst in the heat.

You don't need to make a volcano to do this experiment, it just makes it more fun. You can just use a glass placed in a bowl as your volcano.
