Elephant Toothpaste Experiment

The elephant toothpaste experiment is a great way to have some science fun at home! 

Elephant toothpaste always creates wonder and curiosity in my kids. They love seeing the end result of this experiment. It is always fun to mix it up and try different bottles to see if there is a difference. 

This summer, we plan to do one planned activity a day thanks to the Intentional Summer Kit. Elephant toothpaste is one of the fun activities in the zoo week! 

Are you ready to try this experiment?

Elephant Toothpaste

First, gather the supplies. 

• Clean Water Bottle
• 1/2 cup 6% Hydrogen Peroxide Liquid
• 1 Packet Dry Yeast
• 3 Tablespoons Warm Water
• 1 Tablespoon Liquid Dish Soap
• Food Coloring (optional)

Now you are ready to start the experiment. 

If you can, do this experiment outside so there is less mess. I like to set the bottle in a shallow bin so the overflow is easily cleaned up. 

Pour 1/2 cup of hydrogen peroxide into the bottle, using a funnel if necessary. Then add about 10 drops of food coloring into the bottle.

Next, you will mix 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it. This will create more foam in the reaction.

In a separate cup or bowl, add warm water and the yeast packet. Mix for 30 seconds.

Now you are ready to see what happens! As you get ready, ask your kids what they think will happen. 

Pour the yeast mixture into the water bottle and watch the foam overflow! 

Try different variations!

See what happens if you do not use the dish soap or if you use a different-sized water bottle! It is fun for kids to take guesses on what they think will happen! We love this activity for some simple summer fun. Make sure to grab the Intentional Summer Kit with other fun activities for kids.
