Getting Started with the National Geographic Volcano Kit
Before diving into the experiment, it’s essential to prepare your workspace and understand the kit's components.
Kit Components
The typical National Geographic Volcano Kit includes:
- A volcano mold or model
- Baking soda (sodium bicarbonate)
- Vinegar (acetic acid)
- Red and brown food coloring (to simulate lava)
- Dish soap (to create foam)
- Measuring cups and spoons
- Safety goggles and gloves (recommended)
- Instruction booklet with detailed steps
Ensure all components are present before beginning. Read through the entire set of instructions to familiarize yourself with the process.
Safety Precautions
Although the experiment is safe, it involves household chemicals that can cause irritation if mishandled. Follow these safety tips:
- Wear safety goggles and gloves during the eruption.
- Conduct the experiment in a well-ventilated area.
- Keep vinegar and baking soda away from eyes and mouth.
- Supervise children during the activity.
- Clean up spills promptly and wash hands afterward.

Preparing the Volcano Model
Assembling the Model
Most kits come with a pre-made volcano mold, but some may require assembly:
1. Place the volcano mold on a tray or a waterproof surface to catch spills.
2. If the mold is collapsible, assemble it according to the instructions, ensuring it’s stable.
3. Optional: Decorate or paint the exterior of the volcano to enhance realism, but wait until after the eruption to avoid damage.
Preparing the Eruption Mixture
The main "lava" is created from a mixture of:
- Food coloring (red or orange for lava, brown for ash)
- Dish soap (to produce foam)
- Vinegar (acidic component)
- Baking soda (base component)
Follow these steps:
1. Fill a measuring cup with approximately 1/2 cup of vinegar.
2. Add 2-3 drops of red or orange food coloring.
3. Add a few drops of dish soap.
4. Mix gently to combine.

Performing the Volcano Eruption
Step-by-Step Instructions
1. Place the prepared volcano model on a stable, flat surface.
2. Add 1-2 tablespoons of baking soda into the volcano's crater or opening.
3. Quickly pour the prepared vinegar mixture into the volcano.
4. Step back immediately to observe the eruption.
The chemical reaction between baking soda (a base) and vinegar (an acid) produces carbon dioxide gas, which creates bubbling foam that erupts from the volcano's vent, mimicking a volcanic eruption.
Observing the Eruption
As the reaction occurs:
- Foam will spill over the sides of the volcano.
- The "lava" will flow down, simulating real volcanic lava flows.
- The reaction should last about 10-15 seconds but can vary depending on the amount of ingredients used.
Encourage learners to observe:
- The color and texture of the foam.
- How the foam flows and spills.
- The duration and intensity of the eruption.

Variations and Enhancements
To deepen understanding and enhance the experiment, consider the following variations:
Adjusting the Reaction
- Use more baking soda for a larger eruption.
- Use less vinegar for a smaller flow.
- Add more food coloring for more vivid lava.
Creating Multiple Eruptions
- Reset the volcano by cleaning the model, then repeat the process.
- Alternatively, prepare a new mixture with fresh baking soda and vinegar.
Simulating Different Types of Volcanoes
- Shape the model to resemble different volcano types (shield, stratovolcano, cinder cone).
- Use different amounts of ingredients to simulate varying eruption sizes.
Adding Realism
- Incorporate small rocks or ash powder into the foam.
- Use modeling clay or papier-mâché to create realistic volcano features.

Cleaning Up After the Eruption
Proper cleanup ensures safety and preserves the model for future experiments:
- Wipe the volcano and surrounding surface with a damp cloth.
- Rinse any leftover chemicals with water.
- Store unused ingredients in sealed containers.
- Dispose of leftover mixture responsibly—avoid pouring large quantities down the drain if possible.
- Wash hands thoroughly after handling chemicals and cleaning.

Understanding the Science Behind the Eruption
The National Geographic Volcano Kit provides a hands-on way to learn about volcanic processes. The core chemical reaction involved is:
NaHCO₃ + CH₃COOH → CO₂ + H₂O + NaCH₃COO
Where:
- Baking soda (NaHCO₃) reacts with vinegar (acetic acid, CH₃COOH).
- Carbon dioxide (CO₂) gas forms bubbles, causing foaming and eruption.
- The foam flows out of the volcano’s opening, simulating lava.
This experiment demonstrates:
- Acid-base reactions
- Gas production
- Eruption dynamics
Understanding these concepts helps learners appreciate real-world volcanic activity and geological phenomena.

Additional Tips for a Successful Eruption
- Use fresh vinegar and baking soda for optimal reaction.
- Experiment with different amounts to control eruption size.
- Conduct the activity outdoors or in a space that can be easily cleaned.
- Record observations to compare different eruptions.
- Encourage hypotheses about how changing ingredients affects the eruption.
