Today’s curriculum lesson was a big hit! The Dr. Day Care Toddler and Preschool classrooms made elephant toothpaste!
Try it yourself at home:
Materials
- 16 oz empty plastic bottle (try different shaped bottles and evaluate the results when there’s a narrow neck, wide opening, etc.)
- 1 cup 40-volume hydrogen peroxide (12% solution)
- Funnel
- Squirt of Dawn dish soap
- 3-4 drops of food coloring
- 1 packet dry active yeast
- 4 tablespoons very warm water
- pan with 2-inch sides
Take an empty bottle and carefully add 1 cup of 40 Volume Hydrogen Peroxide using a funnel. Add a few squirts of dish soap. Swirl gently. Take one full packet of yeast and add it to 4 tablespoons of very warm water. Stir will. Place bottle with Hydrogen Peroxide and Soap in a container and using a funnel, add yeast mixture. Immediately remove funnel and step back to watch the show! The foam and bottle will be very warm – so please have an adult cautiously check the temperature before allowing children to play in the foam. The resulting foam is a SOAP foam (no peroxide left!) so it is safe to handle once it has cooled.
