Erupting Volcano | CMSMatHome

Make an erupting volcano science experiment for kids from the Children's Museum of Southern Minnesota

We’re going outdoors again with #CMSMatHome!
Gather a plastic cup, some water, baking soda, dish soap, washable paint, white vinegar, and measuring scoops. Find a good spot for making a mess… err, science. Place your cup on the ground and fill with water, about two-thirds full. Add five tablespoons of baking soda, one teaspoon of dish soap, and several drops of washable paint (this is optional), and stir well. Add one cup of vinegar and observe the eruption of your homemade volcano!
Show us your videos; we’d love to see them!

Further Your Learning

  • You can add vinegar again and compare the outcome. What is different?
  • Why does adding vinegar cause the volcano to erupt?
  • Where is the world largest volcano?
  • Learn more about volcanoes here.
