The Ultimate Elephant Toothpaste Experiment: A Foamy Delight!

Hello, fellow parents and hat enthusiasts! My name is Ava, and I am excited to share a fantastically foamy and fun experiment you can do with your kids. At “All Them Hats,” we love to explore the various roles we play as parents, and today, we’re putting on our “scientist” hats for an extraordinary experience. So, grab your lab coats and goggles and get ready for the ultimate Elephant Toothpaste experiment!

What You’ll Need:

The Elephant Toothpaste Experiment:

If you haven’t heard of Elephant Toothpaste, it’s a classic, easy-to-do, and captivating experiment that demonstrates the wonders of chemistry. It involves a simple chemical reaction that generates an impressive amount of foam, which resembles toothpaste being squeezed from a giant tube – big enough for an elephant! This experiment is perfect for a weekend activity or even an educational moment at a birthday party.


  1. Safety first! Make sure everyone participating is wearing safety goggles and disposable gloves to protect their eyes and skin from any potential splashes.
  2. Pour 150 ml of 3% hydrogen peroxide into the large container. Note: Although it’s possible to use a higher concentration of hydrogen peroxide, we recommend sticking to the 3% solution commonly found at drugstores. This concentration ensures a safe and manageable reaction.
  3. Add 1-2 tablespoons of liquid dish soap to the hydrogen peroxide. If you want to add some color to your foam, put a few drops of food coloring along the inside edge of the container.
  4. In a separate small cup or container, mix 1 tablespoon of active dry yeast with 50 ml of warm water. Stir the mixture until the yeast is fully dissolved.
  5. Here comes the exciting part! Quickly pour the yeast mixture into the hydrogen peroxide container and stand back. You’ll witness a fantastic eruption of foamy goodness!

The Science Behind the Foam:

The Elephant Toothpaste experiment showcases the chemical reaction between hydrogen peroxide and yeast. Yeast acts as a catalyst, breaking down hydrogen peroxide into water and oxygen gas. The dish soap traps the released oxygen gas, creating a massive amount of foam. The food coloring adds a touch of whimsy, making the experiment even more visually appealing.

Parenting Tips:

  1. Supervise your children throughout the experiment to ensure their safety.
  2. Take this opportunity to discuss the science behind the reaction, teaching them about chemical reactions, catalysts, and the importance of safety in science.
  3. Encourage your children to ask questions and make observations, fostering their curiosity and critical thinking skills.

The Elephant Toothpaste experiment is a wonderful way to explore the joys of chemistry with your children while wearing your “scientist” hat. It’s an engaging and entertaining activity that can inspire a love for science, making it a must-try for parents and kids alike. So, gather your supplies and create your very own foamy spectacle!
