How To Make a Volcano for Kids


If you want to captivate your child’s imagination and teach them about acids and bases, look no further than a volcano science experiment. Creating a volcano eruption in your own backyard is a fantastic way to engage your child in hands-on learning. In this article, we will guide you through the step-by-step process of making a volcano and offer alternative methods to explore this exciting experiment. Let’s dive in!

Things You’ll Need for the Volcano Science Project

Before you begin, gather the following materials, most of which you may already have at home:

  • 100 ml of warm water
  • 10 ml of dish soap
  • 400 ml of white vinegar
  • Empty 2-litre soda bottle
  • 2 drops of red food coloring
  • Baking soda slurry (½ cup baking soda and ½ cup water)

A Step-By-Step Guide on How to Make a Volcano for Kids

Now that you have everything you need, follow these simple steps to create your volcano:

  1. Mix the dish soap, water, white vinegar, and food coloring in the empty soda bottle.
  2. Create a baking soda slurry by thoroughly mixing ½ cup of baking soda and ½ cup of water.
  3. Carefully pour the baking soda slurry into the bottle.
  4. Step back and prepare to be amazed as your volcano erupts and spills red lava!

Understanding the Science Behind the Volcano Eruption Experiment

As your homemade volcano erupts, your child may be curious about the science behind it. Here are a few questions to spark their understanding:

  • What did you learn from the volcano eruption experiment?
  • Why do you think the liquid in the soda bottle erupted when you added the baking soda slurry?
  • How does the volcano science project work?

The volcano eruption occurs due to a chemical reaction between an acid (acetic acid in vinegar) and a base (sodium hydrogen carbonate in baking soda). This reaction produces carbon dioxide gas, causing the volcano to erupt. The dish soap becomes foamy, creating bubbles that resemble lava.

5 Creative Ways to Make a Volcano at Home

If you want to explore different methods of making a volcano, try these exciting alternatives:

Tape Volcano


  • Vinegar
  • Tall plastic container
  • Baking soda
  • Acrylic paints
  • Plastic plate
  • Tape


  1. Tape the top of your tall plastic container to the side of your plastic plate, creating the volcano shape.
  2. Paint your “volcano” with brown acrylic paint.
  3. Add a few drops of baking soda and vinegar inside the volcano to witness the eruption. Enhance the visual effect by adding red food coloring for realistic lava.

Ice Volcano


  • Plastic wrap
  • Balls
  • Small bowls


  1. Place a ball at the bottom of each bowl, ensuring they don’t float.
  2. Line each bowl with plastic wrap.
  3. Add a mixture of baking soda, water, and food coloring to cover the ball completely.
  4. Freeze the bowls.
  5. Remove the frozen “volcano” from the bowl and add a few drops of vinegar to trigger the eruption.

Sand Volcano


  • Sand
  • 1 tbsp baking soda
  • 2 cups vinegar
  • Funnel
  • Empty plastic bottle
  • Red/orange food coloring


  1. Place an empty plastic bottle in a mound of sand.
  2. Use a funnel to add baking soda to the bottle.
  3. Mix food coloring and vinegar, then pour the mixture into the bottle. Watch the volcano erupt!

Mini Volcanoes


  • Egg carton
  • Scissors
  • Baking soda
  • Vinegar
  • Various colors of food coloring


  1. Cut out the bottom of each egg holder in the carton and flip it over to resemble mini volcanoes.
  2. Pour some baking soda into each slot.
  3. Add colored vinegar solutions to create eruptions of various colors.

Newspaper Volcano


  • Newspaper
  • Cardboard
  • Large plastic bottle
  • Cellulose adhesive
  • Paint
  • Scissors


  1. Place a bottle in the middle of your cardboard base and apply adhesive paste all over it.
  2. Glue crumpled newspaper over the cardboard, including the bottle, and let it dry.
  3. Once dry, pour baking soda, vinegar, and food coloring into the bottle to make the volcano erupt.
