How To Make An Erupting Volcano

Share

Use baking soda and vinegar to create an awesome chemical reaction! Watch as it rapidly fizzes over the container and make sure you’ve got some towels ready to clean up.

6-8 drops food coloring – your favorite color
4 heaping tablespoons baking soda
1 cup vinegar *add last*

 

What’s happening?

The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.

For extra effect you can make a realistic looking volcano. It takes some craft skills but it will make your vinegar and baking soda eruptions will look even more impressive!

Why This Works?

Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate (NaHCO3) and vinegar is an acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide.
