So, let’s dive in and discover how to create your own Elephant Toothpaste!

Introduction to Elephant Toothpaste

What is Elephant Toothpaste?

Elephant Toothpaste is a foamy substance that erupts out of a container, resembling a frothy explosion. The reaction is a result of the decomposition of hydrogen peroxide, which is accelerated by the addition of a catalyst. It is commonly used as a demonstration in science classes to showcase the power of chemical reactions.

Why is it called Elephant Toothpaste?

The name “Elephant Toothpaste” was coined due to the voluminous foam produced during the reaction. The massive amounts of foam resemble the toothpaste an elephant might use to clean its enormous teeth! This whimsical name adds a touch of fun to the experiment and captures the imagination of both kids and adults alike.

Importance of Learning How to Make Elephant Toothpaste

Learning how to make Elephant Toothpaste is not only entertaining but also educational. It provides a hands-on experience that sparks curiosity and promotes scientific thinking. By understanding the underlying chemical reactions, participants gain insights into the properties of different substances and the factors that influence their interactions. It’s an excellent opportunity to introduce scientific concepts in a practical and engaging manner.

Step-by-Step Guide on Making Elephant Toothpaste

Before we get our hands dirty, it’s crucial to follow some safety precautions to ensure a safe and enjoyable experience. Remember, safety first!

Safety Precautions

  • Put on safety goggles and gloves to protect your eyes and skin from any potential splashes or spills.
  • Perform the experiment in a well-ventilated area to avoid inhaling any fumes.
  • Keep children under adult supervision throughout the process.
  • Avoid direct contact with the hydrogen peroxide, as it may cause skin and eye irritation.

Now that we’ve covered the safety aspects, let’s move on to the exciting part – mixing the ingredients!

Mixing the Ingredients

  1. Combining Hydrogen Peroxide and Dish Soap

    • Take a clean container or a plastic bottle and pour about half a cup of hydrogen peroxide into it.
    • Add a generous squirt of liquid dish soap to the container.
    • Gently swirl the mixture to ensure thorough mixing.
  2. Activating the Yeast

    • In a separate bowl, mix one tablespoon of yeast with three tablespoons of warm water.
    • Stir the mixture gently until the yeast dissolves completely.
    • Allow the yeast mixture to sit undisturbed for a few minutes to activate.
  3. Adding the Yeast Mixture to the Hydrogen Peroxide Solution

    • Slowly pour the activated yeast mixture into the container with the hydrogen peroxide and dish soap mixture.
    • Stand back and watch the magic unfold!

The Reaction Process

Why does the reaction occur?

The reaction occurs due to the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2). Hydrogen peroxide is a stable compound, but it decomposes into water and oxygen when exposed to a catalyst like the yeast used in this experiment. The dish soap helps to trap the released oxygen gas, creating the foamy eruption.

Understanding the science behind the reaction

The decomposition reaction can be represented by the following equation:

2 H2O2 → 2 H2O + O2

The yeast acts as a catalyst, which means it speeds up the reaction without being consumed itself. When the yeast comes into contact with the hydrogen peroxide, it breaks down the hydrogen peroxide molecules into water and oxygen. The dish soap helps to create a stable foam by trapping the oxygen gas and preventing it from escaping rapidly.

Safety Measures during the Reaction

While the reaction is fascinating to watch, it’s essential to maintain safety precautions throughout the process. Here are some tips to ensure a safe experience:

  • Maintain a safe distance from the reaction, as the foam can expand rapidly.
  • Avoid touching the foam directly, as it may still contain traces of hydrogen peroxide.
  • Dispose of the foam and the remaining mixture properly, as hydrogen peroxide can be harmful to the environment.

Tips and Variations for Making Elephant Toothpaste

Now that you’ve successfully created your Elephant Toothpaste, let’s explore some tips and variations to further enhance your experience.

Experimenting with different concentrations of Hydrogen Peroxide

You can experiment with various concentrations of hydrogen peroxide to observe the impact on the reaction. Higher concentrations tend to create more vigorous foaming, while lower concentrations may result in a milder reaction. Just remember to exercise caution when working with higher concentrations and always wear protective gear.

Using different dish soaps for unique results

Try using different types of liquid dish soaps to see how they affect the reaction. Some dish soaps may produce denser foam, while others may create larger bubbles. This variation adds an element of surprise to the experiment and allows you to explore the diverse properties of different dish soaps.

Adding glitter or other decorative elements

To make your Elephant Toothpaste more visually appealing, you can add a sprinkle of glitter or other decorative elements. This not only enhances the aesthetic aspect but also adds an extra element of excitement and personalization to the experiment.

Storing and disposing of Elephant Toothpaste safely

After the experiment, make sure to dispose of the remaining mixture and foam responsibly. Hydrogen peroxide can be harmful to the environment, so dilute the mixture with water and pour it down the drain. Clean the container thoroughly before storing or reusing it for future experiments.


Making Elephant Toothpaste is an exciting and educational science experiment that captivates both kids and adults. By following a simple step-by-step guide, you can create a foamy eruption that demonstrates the power of chemical reactions. Remember to prioritize safety, experiment with different variations, and dispose of the materials responsibly. So, gather your ingredients, put on your safety goggles, and embark on this thrilling journey of scientific discovery with Elephant Toothpaste!
