Introduction to Elephant Toothpaste
Elephant toothpaste is a fascinating chemistry experiment that demonstrates a rapid chemical reaction. The reaction produces a large amount of foam that resembles toothpaste being squeezed from a tube, but on a much larger scale. This experiment is not only visually impressive but also an excellent way to teach children about chemical reactions and the properties of gases.
When learning how to make elephant toothpaste with baking soda, it's important to understand the role of each ingredient. Baking soda acts as a catalyst in the reaction, speeding up the decomposition of hydrogen peroxide into water and oxygen gas. This release of oxygen gas is what creates the foamy eruption that characterizes elephant toothpaste.
Materials Needed
Before you begin, gather all the necessary materials to ensure a smooth and successful experiment. Here's a list of what you'll need:
- Hydrogen peroxide (3% or higher)
- Baking soda
- Dish soap
- Food coloring (optional)
- Empty plastic bottle
- Measuring cups and spoons
- Safety goggles
- Protective gloves
- Tray or container to catch the foam
Step-by-Step Guide
Step 1: Prepare the Workspace
Choose a safe and open area for your experiment. Place a tray or container underneath the plastic bottle to catch the foam. Wear safety goggles and gloves to protect yourself from any splashes.
Step 2: Mix the Hydrogen Peroxide and Dish Soap
Pour the hydrogen peroxide into the plastic bottle. Add a few drops of dish soap and mix gently. The dish soap will help trap the oxygen gas and create the foamy texture.
Step 3: Add Food Coloring
If you want to add some color to your elephant toothpaste, drop a few drops of food coloring into the mixture. Swirl the bottle gently to distribute the color evenly.

Step 4: Add Baking Soda
Measure out a small amount of baking soda and sprinkle it into the bottle. Watch as the reaction begins, creating a foamy eruption that spills out of the bottle.
The Science Behind Elephant Toothpaste
The reaction that creates elephant toothpaste involves the decomposition of hydrogen peroxide into water and oxygen gas. Baking soda acts as a catalyst, speeding up this process. When hydrogen peroxide decomposes, it releases oxygen gas, which is trapped by the dish soap to form bubbles. This combination results in the characteristic foam that makes elephant toothpaste so visually appealing.
Safety Precautions
While elephant toothpaste is generally safe to make, there are a few precautions to keep in mind:
- Wear safety goggles and gloves to protect your eyes and skin.
- Use hydrogen peroxide with caution, especially if using concentrations higher than 3%.
- Conduct the experiment in a well-ventilated area.
- Dispose of the foam properly after the experiment.
Variations of the Experiment
Using Different Catalysts
Instead of baking soda, you can use other catalysts like potassium iodide or yeast. Each catalyst will produce a slightly different reaction, offering a new learning experience.
Changing the Concentration of Hydrogen Peroxide
Experiment with different concentrations of hydrogen peroxide to observe how it affects the reaction. Higher concentrations will produce a more vigorous eruption, but they also require extra safety precautions.
Tips for Success
To ensure a successful elephant toothpaste experiment, follow these tips:
- Measure your ingredients carefully for consistent results.
- Use a tall, narrow bottle to enhance the visual effect of the foam eruption.
- Experiment with different food coloring combinations for a colorful display.
- Clean up immediately after the experiment to prevent stains.
