Homemade Volcano for Kids

This easy volcano experiment will be a blast for everyone.  Whether you love doing science experiments at home or the kids have one for a homework assignment, give it a try. This outdoor volcano experiment is so fun but also a great way to learn at the same time.

I love when we can do things together that are fun and learn new things as well. Plus, we are making lasting memories and making a baking soda volcano.

The kids will be super impressed with how this volcano erupts while learning how science works. You only need a few things to make a volcano for this cool science project.

The Science Behind the Volcano Eruption

The eruption happens due to a reaction between an acid and a base. The acetic acid in the vinegar reacts with the sodium hydrogen carbonate that is in the baking soda.

This produces carbon dioxide. The base has a reaction when exposed to the acid. Then the gas results in the eruption inside the DIY Volcano.

What do you need to make a volcano?

  • Used and Empty Water Bottle with the top cut off
  • 1 cup Water
  • 4 Tablespoons of Baking Soda
  • 1 teaspoon of Dish Soap
  • Food Coloring of your Choice
  • 1 cup of Vinegar
Process of making volcano.

How do you make a volcano explode:

  • Step 1. Cut the neck off of the top of the plastic bottle to make the volcano shape. You can also utilize an empty soda bottle for this classic science project.
  • Step 2. Place the water bottle on the location where the eruption will occur.  I used a jelly roll pan and covered it in foil first for easy clean up. However, you can also do this volcano science experiment outside so clean up is even easier!
  • Step 3. Put the warm water, baking soda, dish soap and drops of food coloring in the water bottle. 

    We used drops of red food coloring for the lava baking soda slurry but you can use any color you want. Gently combine this liquid mixture with a spoon so that they are combined for the baking soda and vinegar reaction.

  • Step 4. Next have the kids gather around the water bottle to get ready for the experiment. It is eruption time! The vinegar added to baking soda create carbon dioxide gas.
  • Step 5. Then use a separate cup to pour vinegar into the water bottle ingredients and watch the volcano erupt from the chemical reaction in this vinegar volcano.

This experiment is quick and easy. The kids can easily take turns creating their own real volcanoes. We absolutely love science experiments for kids that are fun and teach simple science ideas.

This volcanic eruption is one of the easiest kids activities and so much fun. While other types of experiments use playdough, flour, salt dough or other ingredients, this is very simple with baking soda, vinegar and other basic supplies.
