In this article post we write about making of the volcano working model science project for exhibition – diy – simple and easy
Creating a volcano eruption model using a bottle, newspaper, vinegar, and baking powder is a classic and exciting science project. This project demonstrates a simple chemical reaction that mimics a volcanic eruption. Here’s how you can make and demonstrate this model:
Materials Needed:
- Plastic bottle (small size, like a soda bottle)
- Newspaper
- Vinegar
- Baking powder (or baking soda)
- Dish soap (optional, for added foaming effect)
- Red food coloring (optional, to simulate lava)
- Water
- Tape or glue
- Paint (optional, for decoration)
- Large tray or plastic sheet (to catch any overflow)

Steps to Create the Volcano Model:
- Prepare the Base Structure:
- Mount the Bottle: Place the plastic bottle in the center of a tray or a sturdy base. Ensure it stands upright.
- Newspaper Structure: Tear the newspaper into strips. Mix some water with a little bit of glue to make a paste. Dip the newspaper strips into the paste and start building the volcano shape around the bottle. Leave the bottle opening exposed.
- Shape the Volcano:
- Form the Cone: Continue layering the newspaper strips to form a cone shape, resembling a volcano. Make sure the structure is sturdy and dry it completely.
- Detailing: Add more layers for thickness and shape the newspaper to give the volcano a realistic look with ridges and bumps.
- Decoration (Optional):
- Painting: Once the newspaper structure is dry, paint it to look like a volcano. Use brown, gray, and black for the rock, and red and orange for lava streaks.
- Landscaping: You can add green paint or small pieces of green paper around the base to represent grass or trees.
- Prepare for the Eruption:
- Add Baking Powder: Put 2-3 tablespoons of baking powder into the bottle. You can also add a few drops of dish soap to enhance the foaming effect.
- Food Coloring: Add a few drops of red food coloring into the bottle to give the eruption a lava-like appearance.
- Eruption Setup:
- Vinegar Preparation: Pour vinegar into a separate container. When you’re ready to demonstrate the eruption, have this container handy.
- Demonstrate the Eruption:
- Trigger the Eruption: Pour vinegar into the bottle quickly. The reaction between the vinegar (acid) and baking powder (base) will produce carbon dioxide gas, causing the mixture to foam and bubble out of the bottle, simulating a volcanic eruption.
- Observe: Watch as the “lava” flows down the sides of your model volcano.
Explanation of the Science:
- Chemical Reaction: The vinegar (acetic acid) reacts with the baking powder (sodium bicarbonate) to produce carbon dioxide gas. T
- Foaming Effect: The carbon dioxide gas forms bubbles in the liquid, creating foam. The dish soap (if used) increases the foaminess, making the eruption more dramatic.
