How To Make A Volcano Erupt With Smoke


Volcanoes have always fascinated humans with their raw power and beauty. While real volcanic eruptions are dangerous and unpredictable, you can recreate a miniature version at home, complete with smoke! This article will guide you through the steps to create a volcano eruption experiment that will amaze and educate.

Materials Needed

  • A plastic bottle (like a soda bottle)
  • A small glass or plastic container (to be the volcano crater)
  • Baking soda
  • Vinegar
  • Red food coloring (optional)
  • Dish soap (optional)
  • Newspaper or plastic tablecloth (to protect your surface)

Step-by-Step Instructions

1. Prepare Your Work Area

Before starting, ensure you have a flat and stable surface to work on. Cover it with newspaper or a plastic tablecloth to protect it from any spills or mess.

2. Creating the Volcano Structure

Take the plastic bottle and place it upside down in the center of the work area. This will serve as the base of your volcano. Arrange the small glass or plastic container around the bottle, leaving a hollow space between the bottle and the container. This space will be the volcano crater.

3. Mixing the Eruption Solution

In a separate container, combine approximately two tablespoons of baking soda with a few drops of red food coloring (if desired). Mix them together until well blended. This step is optional but can enhance the visual effect.

4. Preparing the Vinegar Mixture

In another container, pour vinegar, preferably white vinegar, until it fills about one-third of the volcano crater. You can also add a few drops of dish soap to create a foaming effect when the eruption occurs.

5. Erupting the Volcano

Now, it’s time for the eruption! Carefully pour the baking soda mixture into the volcano crater. Step back and watch as the baking soda and vinegar react, causing a volcanic eruption. The chemical reaction between the baking soda (a base) and vinegar (an acid) releases carbon dioxide gas, creating the eruption effect.

Additional Tips

  • Experiment with different amounts of baking soda and vinegar to achieve the desired eruption height and duration.
  • You can also decorate your volcano by painting the exterior to resemble a real volcano.
  • Ensure you have adult supervision, especially when using the vinegar and handling the volcano structure.
  • Do not attempt to touch or taste the eruption mixture, as it may cause irritation.


Creating a volcano eruption with smoke is an exciting and educational experiment that can be enjoyed by people of all ages. By following the simple steps outlined in this article, you can witness the power of a volcanic eruption right in your own home. Remember to have fun, stay safe, and learn more about the fascinating world of volcanoes!
