How To Make A Salt Dough Volcano


If you’re looking for a fun and educational project to do with kids, making a salt dough volcano is a great option. This hands-on activity allows children to learn about volcanoes while also getting creative with their own volcano design. In this article, we will guide you through the process of making a salt dough volcano step by step.

Materials Needed

  • 2 cups of all-purpose flour
  • 1 cup of salt
  • 1 cup of water
  • A plastic bottle
  • Newspaper
  • Acrylic paint
  • Paintbrushes
  • Baking sheet


Step 1: Building the Base

Start by creating the base of your volcano. Mix the flour, salt, and water in a large bowl until the dough is firm and pliable. If the mixture is too sticky, add more flour. Once the dough is ready, shape it into a wide, sturdy base by rolling it and flattening it on a baking sheet. This will serve as the foundation for your volcano.

Step 2: Creating the Volcano Structure

Next, take a plastic bottle and place it upside down on the center of the dough base. Gently press it down to make sure it is securely embedded in the dough. This will form the structure of your volcano. Use your hands to mold additional dough around the bottle, gradually building up the sides of the volcano until you achieve the desired shape and height.

Step 3: Adding the Details

Once the basic structure is complete, use your fingers or a small tool to add details such as rocks, crevices, or lava flows to the surface of the dough volcano. Let your imagination run wild and get creative with the design. Remember that the dough will harden when baked, so it’s a good opportunity to add texture and depth to your volcano.

Step 4: Baking the Salt Dough

Preheat your oven to 200°F (93°C). Carefully transfer the baking sheet with the salt dough volcano to the oven. Bake it for approximately 2-3 hours or until the dough is completely dry and hard. Keep an eye on it to prevent any burning. Once baked, let it cool down completely before moving on to the next step.

Step 5: Painting and Finishing Touches

Now comes the fun part! Set up a workspace with newspaper or a drop cloth to protect the surfaces. Use acrylic paint to bring your volcano to life. Start with a base coat and let it dry before adding layers of colors and details. You can paint the volcano realistically or get creative with vibrant colors. Once the paint is dry, you can add additional touches like smoke or glitter if desired.


Making a salt dough volcano is an enjoyable and educational activity for kids. It allows them to learn about the science behind volcanoes while also getting hands-on with their own creation. By following these simple steps, you can create a unique salt dough volcano that will be a fantastic addition to any science fair project or playtime activity.
