Things You Need For The Volcano Science Project 

Making a volcano at home is an easy and fun project to do with your kids. Here is a list of things you need to perform the volcano science project. Most of the materials on the list are inexpensive and easily available. In fact, you might even find them in your pantry.

Things You’ll Need For Volcano Experiment For Kids:

  • 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

Wondering how to make a homemade volcano? It’s pretty simple. Here is a step-by-step guide to performing the volcano science experiment with your kids.

  • Step 1: Mix the dish soap, water, white vinegar, and food coloring and pour it into the empty soda bottle.
  • Step 2: Make a baking soda slurry with ½ cup baking soda and ½ cup water. Mix it thoroughly with a spoon, until it’s completely dissolved.
  • Step 3: Now, it’s eruption time! Quickly but carefully pour this slurry into the bottle and step back.  Now, watch the volcano erupt and spill out red lava!

The Science Behind The Volcano Eruption Experiment

The volcano science experiment will leave your kids in awe as the homemade volcano erupts and spills out red lava. Help them understand the science behind the experiment by asking them questions and giving them hints. Here is a list of questions to help you start.

  • 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 to it?
  • How does the volcano science project work?

The homemade volcano erupts because of a chemical reaction between an acid and a base. The acetic acid present in the vinegar reacts with the sodium hydrogen carbonate in the baking soda and produces carbon dioxide. The base (sodium hydrogen carbonate) undergoes a decomposing reaction when it is exposed to the acid. This produces a gas called carbon dioxide, which causes the homemade volcano to “erupt!” The dish soap becomes foamy and the bubbles and spill out like lava.

5 Creative Ways To Make A Volcano At Home

Do you know there are several ways to make a volcano at home? Now that you know the science behind volcano eruptions, here are 5 more ways to make a volcano at home!

Tape Volcano

Things you need:

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


  • Step 1: For this baking soda vinegar volcano, tape the top of your tall plastic container to the side of your plastic plate. The plate serves as the base for your volcano. Continue to add tape around your container in this fashion. 
  • Step 2: Paint your ‘volcano’ with acrylic paint. (We recommend using brown paint) 
  • Step 3: Once you’re done making your volcano, add a few drops of baking soda and vinegar inside the volcano and watch it erupt! You can add some red food coloring to make the volcano look more realistic with red lava spilling out.

Ice Volcano

Things you need:

  • Plastic wrap
  • Balls
  • Small bowls


  • Step 1: To build an ice volcano, place a ball (that doesn’t float) at the bottom of each bowl. Line each of these bowls with plastic wrap. 
  • Step 2: Next, add a mixture of baking soda, water, and food coloring to these bowls so that they completely cover the ball underneath. 
  • Step 3: Place these bowls in the freezer for some time. 
  • Step 4: Once they’re frozen, pry out your ‘volcano’ from the bowls and add a few drops of vinegar into it. Your ice volcano will erupt as soon as the vinegar touches it!

Sand Volcano

Things you need:

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

Instructions: Want to build a sand volcano in your backyard? Here’s how you can do it. 

  • Step 1: First, place an empty plastic bottle in a mound of sand. 
  • Step 2: Use a funnel to add some baking soda to the bottle. 
  • Step 3: Mix some food coloring and vinegar together and pour this mixture inside the bottle and watch your volcano erupt!

Mini Volcanoes

Things you need:

  • Egg carton
  • Scissors
  • Baking soda
  • Vinegar
  • Red, blue, green, yellow, orange and pink food coloring

Instructions: Here’s how to make a volcano for kids using an egg carton. 

  • Step 1: Cut out the bottom of each egg holder in your egg carton and flip it over. You’ll notice that each slot now looks like a mini volcano. 
  • Step 2: Pour some baking soda into each slot. 
  • Step 3: Then, add some colored vinegar solution (vinegar + food coloring) into the slot. You can create several different colored eruptions in this way. The colorful eruptions will leave your child in awe.

Newspaper Volcano

Things you need:

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

Instructions: Make a volcano at home using newspaper! 

  • Step 1: First, place a bottle in the middle of your cardboard base. Apply the adhesive paste all over the cardboard and glue the crumpled newspaper over it. 
  • Step 2: Then, glue the newspaper around your bottle too, and paint the entire structure to ensure it looks like a volcano. Set it aside and allow it to dry for a couple of hours or days. 
  • Step 3: When it’s ready, ask your child to pour the baking soda, vinegar, and food coloring into the bottle to make the volcano erupt.

We hope you enjoy making these volcano science projects with your little one. These experiments hone their understanding of science and instill in them a sense of creativity and imagination.
