How to Make Elephant Toothpaste : A Step-by-Step Guide

How to Make Elephant Toothpaste

Do you want to try a fun and exciting science experiment that will amaze your friends? Look no further, because today we will show you how to make “Elephant Toothpaste” right at home! This experiment is not only educational but also a lot of fun.

Materials You Will Need

Before we begin, let’s gather the materials you will need:

Materials Quantities
1 plastic soda bottle 1
Hydrogen peroxide (6% or higher concentration) 100 ml
Dish soap 1 tablespoon
Dry yeast 1 tablespoon
Warm water 3 tablespoons
Food coloring (optional) A few drops
Pan or tray (to catch the foam) 1


Now that you have gathered all the necessary materials, let’s proceed with the steps to create your own Elephant Toothpaste:

  1. Clear a workspace and cover it with newspaper or a plastic tablecloth to protect against spills.
  2. Place the plastic soda bottle in the center of the pan or tray.
  3. In a small bowl, mix the warm water and dry yeast together until the yeast is dissolved.
  4. Pour the hydrogen peroxide into the plastic soda bottle.
  5. Add the dish soap to the bottle and gently swirl it around to mix.
  6. If desired, add a few drops of food coloring to the bottle for a colorful effect.
  7. Carefully pour the yeast mixture into the bottle, and quickly step back.
  8. Observe the amazing reaction as the foam starts to shoot out of the bottle, resembling a toothpaste squeezed by an elephant!
  9. You can let the foam overflow into the pan or tray, but make sure to clean it up afterward.

How Does it Work?

This exciting experiment is actually a chemical reaction between the hydrogen peroxide and the yeast. The hydrogen peroxide breaks down into water and oxygen gas, but this process happens slowly on its own. When yeast is added, it acts as a catalyst, speeding up the reaction and resulting in a rapid release of oxygen gas.

The dish soap helps to create bubbles and foam by trapping the oxygen gas released from the reaction. The foam appears like “elephant toothpaste” because of its volume and resemblance to the action of squeezing toothpaste out of a tube.

Safety Precautions

While this experiment is safe when performed correctly, it’s essential to follow some safety precautions:

  • Wear safety goggles to protect your eyes from any splashes that may occur.
  • Perform the experiment in a well-ventilated area to avoid inhaling the gas.
  • Adult supervision is recommended, especially for younger children.
  • Dispose of the leftover mixture appropriately and clean the workspace thoroughly.
  • Do not touch or taste the foam, as the reaction mixture may still contain unreacted hydrogen peroxide.

In Conclusion

Congratulations! You have successfully created your very own Elephant Toothpaste. How did it feel to witness the colorful foam shooting out like a toothpaste explosion? We hope you had a blast with this experiment and learned a little about chemical reactions along the way.

Remember, science experiments are not only fun but also a great way to explore and understand the world around us. So, keep exploring, experimenting, and discovering new things!

Frequently Asked Questions On How To Make Elephant Toothpaste : A Step-by-step Guide

What Are The Ingredients Needed For Elephant Toothpaste?

To make Elephant Toothpaste, you will need hydrogen peroxide, dish soap, yeast, warm water, and a container.

How Does Elephant Toothpaste Work?

When mixed, hydrogen peroxide breaks down into oxygen and water, and the yeast acts as a catalyst, producing a foam.

Is Elephant Toothpaste Safe For Kids?

Elephant Toothpaste should be made under adult supervision as the mixture can cause skin irritation and can be harmful if ingested.

Can I Use Any Type Of Hydrogen Peroxide?

It is recommended to use 30% hydrogen peroxide for the best results in making Elephant Toothpaste.
