Classic Baking Soda and Vinegar Volcano Science Experiment

We’ve turned the classic baking soda and vinegar experiment for kids into a volcano more times than I can count, but my kids still love trying it over and over.

This time, we kept things really simple by making this easy baking soda and vinegar volcano experiment out of play dough and a beaker.

The play dough volcano was a hit with both elementary and preschool kids, and even the clean up was easy for this one. If you need a low-mess science experiment, this one definitely fits the bill.

How do you make a baking soda and vinegar volcano science experiment with play dough?

Teaching kids how to make a volcano with baking soda and vinegar is super easy!

Since this baking soda and vinegar science experiment makes the play dough wet, it is a great way to use play dough that is about to dry out or play dough that is all combined with other colors. You could also use homemade play dough to make this volcano.

Materials for the Play Dough Volcano:

  • Play Dough
  • Plastic Beaker
  • Baking Soda
  • Vinegar
  • Dish Soap
  • Washable Paint

How to Make a Vinegar and Baking Soda Volcano Science Experiment:

Create the best play dough volcano science experiment in the world with these simple instructions:

Step 1:

Create the mixture to put inside the volcano.

  • Mix up to a cup of baking soda and 1-2 oz of paint together along with a small amount of dish soap, about 1 tsp. The dish soap will help the volcano erupt slower, making this easy volcano experiment last longer.
  • Add a touch of water if the mixture is too thick.
  • Pour 1/2 cup to 1 cup baking soda mixture into the beaker.

Step 2:

Place the beaker on your tray. You can secure it in place with a bit of masking tape as you get ready to create your volcano with play dough.

Figuring out how to build a play dough volcano with a beaker or soda bottle is also a great way to sneak in some fine motor skills practice with your kids.

(I always love sneaking in fine motor skills with my kids…even the older ones who seem to use their thumbs for texting more than anything else…sigh.)

Step 3:

Place the play dough around the beaker to make it look like a volcano. Don’t cover up the opening of the beaker because you will need the vinegar to get inside to create the chemical reaction.

Step 4:

Pour a small amount of vinegar into the beaker or soda bottle to create the baking soda and vinegar reaction, then, watch the volcano erupt. Keep adding vinegar a little at a time and watch as the vinegar reacts with the baking soda until the volcano no longer erupts any longer.

Of course, the baking soda and vinegar reaction is also great as a drain cleaner, but I think the kids will enjoy this experiment more as them make a vinegar volcano with baking soda & vinegar.

This classic science experiment is always a fun one for kids, and no matter how many times they make it, they still love watching the baking soda and vinegar chemical reaction over and over.

What happens when you mix vinegar and baking soda in the volcano science experiment?

When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar (acetic acid) react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate. The second reaction is a decomposition reaction and carbon dioxide is released. (which is what creates the bubbles)

What kids will really care about more than a scientific explanation is how big their volcano is!
