Volcano experiment
Our Work > Science
To make dough for the volcano use:
- 3 cups flour
- 1 1/2 cups salt
- 6 teaspoons cream of tartar
- 4 tablespoons vegetable oil
- 3 cups water
- Food colouring
In a real volcano, molten rock from deep within the Earth erupts through a volcano (the molten rock is called magma when it is within the Earth and is called lava when it comes out of a volcano).
In this project, a mock volcano will erupt with a bubbly, fizzy liquid that is created by a simple chemical reaction.
This project shows us what happens when an acid (vinegar) and a base (baking soda) interact. Chemically, the acid and base neutralize each other, producing carbon dioxide gas as a by product.
