My son loves science experiments that are messy and incorporate mild explosions. When I saw this experiment, I knew we had to do it. Like many of the science experiments we do, all the ingredients were in our home.

We liked this activity because it was simple and fun. It requires you to use boiled eggs. I used this as an opportunity to expose my son to the science of cooking. While boiling the eggs, we discussed how cooking is transferring energy from a heat source, the stove, to the food. In other words, heat changes food.

Try this experiment at home! Your kids will love it. Doing science experiments will help your child become a better reader.

Let’s Get Started!


  • Bowls for each color you would like
  • Water
  • Paint Brush
  • Baking Soda
  • Measuring Spoons
  • Food Coloring
  • Vinegar
  • Drinking Glass or Plastic Glass – big enough for an egg
  • Plastic container – something to catch the overflow of the liquid
  • Hard boiled eggs

  • Combine and mix water, baking soda, and a few drops of food coloring to make a paste.

  • Fill the drinking glass with vinegar 1/2 full
Plastic Glass of Vinegar
  • Put the glass of vinegar in the plastic container
  • Use the paint brush to paint the egg with the paste
    • For a bigger reaction, put a thick coat of paste on the egg

  • Lower the egg in the glass of vinegar.
  • Now watch the Bubble, Fizz, and Overflow!
Egg Volcano Explosion!


  • Baking Soda is a base and Vinegar is an acid.
  • When Baking Soda and Vinegar mix, the hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda.
  • This mix is the result of two new substances called carbonic acid and sodium acetate.
  • There is a second reaction called decomposition reaction.
  • Decomposition reaction is when carbonic acid is formed.
  • The carbonic acid is decomposed into water and carbon dioxide gas causes the bubbling action.

I hope you like this experiment!

  1. love this volcano science experiment! My almost 8 year old absolutely loves science so I’m going to pin this for later. These types of experiments are awesome for over the winter and rainy days. Thanks!!

  2. This is super fun! My boys would LOVE this! We built a large one last year and oh my the mess. This seems easy, super easy to clean up, and educational. Everything I love in an kids experiment.
