DIY Volcano Mountain

DIY Volcano Mountain

Volcano mountains are scary. Though they are natural phenomena, a volcano can be extremely devastating. In this experiment we are going to make a simple yet interesting volcano in two steps. In the first step we will make a model of volcano and in the second step we will activate the model using some baking soda and vinegar. Although this experiment is safe to do at home, we suggest an adult’s supervision. So, what are you waiting for? Start enjoying your DIY Volcano Mountain.

DIY Volcano Mountain (Part 1): Making a Volcano Model

You need:

  1. An empty bottle
  2. Some newspaper
  3. Some colours
  4. Glue
  5. A hard board for base
  6. Play dough (brown colour)

What next?

Watch our volcano model making video here. The video can explain you the steps much better than written instructions.

DIY Volcano Mountain (Part 2): Live Volcano

You need:

  1. The Volcano Model
  2. Vinegar
  3. Baking Soda
  4. Red or orange food grade colour

What next?

Step 1: Add baking soda to the cavity of volcano mountain model.

Step 2: Add the food grade colour (red or orange) to the cavity of volcano mountain model.

Step 3: Pour in the vinegar through the cavity. Stay aside and watch your volcano mountain erupting.


Vinegar and baking soda reacts and produces carbon dioxide. The production of carbon dioxide forms bubbles to that erupt out through the cavity. If you liked this science project, can you answer the following questions?

  1. Is vinegar acidic? if yes, which one?
  2. Can you write the chemical formula of this reaction?

There are a lot more things that we can do with vinegar.
