How To Make A Salt Dough Volcano?

Salt dough volcanoes are a classic science experiment that never fails to impress. With just a few simple ingredients and some creativity, you can create your very own miniature volcano that erupts with baking soda and vinegar. Follow these steps to make your own salt dough volcano at home.

Materials Needed:

  • 4 cups all-purpose flour
  • 1 cup salt
  • 1 1/2 cups water
  • Baking soda
  • Vinegar
  • Red food coloring


  1. In a large mixing bowl, combine the flour and salt.
  2. Add the water gradually, mixing until a dough forms. You may need to adjust the amount of water slightly to achieve the right consistency.
  3. Knead the dough for a few minutes until smooth and pliable.
  4. Shape the dough into a volcano shape, with a hollowed-out center at the top for the eruption.
  5. Place your volcano on a baking sheet lined with parchment paper.
  6. Bake the volcano in a preheated oven at 200 degrees Fahrenheit for 2-3 hours, or until completely dry and hardened.
  7. Once the volcano has cooled, mix some red food coloring with a small amount of water to create a lava-like mixture.
  8. Pour the baking soda into the hollowed-out center of the volcano.
  9. Add a few drops of the red food coloring mixture to the baking soda.
  10. Finally, pour vinegar into the volcano and watch as it erupts with a foamy lava flow.


  • You can customize your volcano by painting it with acrylic paints once it has dried.
  • Experiment with different ratios of baking soda and vinegar to create bigger eruptions.
  • For added realism, sprinkle some sand or crushed rocks around the base of the volcano.

Making a salt dough volcano is a fun and educational activity that will entertain kids of all ages. Not only does it demonstrate the chemical reaction between baking soda and vinegar, but it also allows for creativity and imagination to run wild. So gather your materials and get ready to create your very own erupting volcano!
