How To: Make Elephant Toothpaste

Some of our team members had the opportunity to participate in the Sloppy Science event at LaunchPAD Children’s Museum in Sioux City this past weekend. It was a great first-year event where kids could watch science demonstrations, create their own experiments, and get sloppy with slime and a sloppy obstacle course.

At the Summit Dental Health booth, we had 3 hands-on activities that were fun for the kids, but also educational.

Kids learned how to floss and then got to practice their new skills with mega blocks, Play-Doh and yarn. We had some pretty enthusiastic new flossers who were pretty excited to win their very own dental floss on our wheel of prizes.

We also did an experiment to show how bacteria in your mouth feeds off sugar and creates cavity-causing plaque.

One of our most popular experiments was making elephant toothpaste while sharing fun facts about elephant teeth. We had several parents ask us how we did it, so we thought we’d share here

Elephant Toothpaste Recipe

Supplies Needed:

  • Pan to catch the toothpaste
  • Empty 16 oz plastic bottle
  • Small bowl
  • Spoon
  • Funnel
  • 3 tbsp. very warm water
  • 2-3 tsp. yeast
  • 1/2 cup hydrogen peroxide (We used the kind you get at a beauty supply store. It’s stronger than the regular kind you have in your medicine cabinet.)
  • 1 tbsp. dish soap


Step 1: Mix the warm water and yeast in a small bowl. Set aside.

Step 2: Place the plastic bottle inside the pan. Using the funnel, pour in the hydrogen peroxide and dish soap.

Step 3: Pour the yeast/water mixture into the bottle. The mixture will bubble over and look like toothpaste coming out of a tube.
