Elephant Toothpaste
A fun and captivating science experiment that demonstrates a colorful and foamy chemical reaction, suitable for all ages.
Ingredients
Main Ingredients
- 16 oz 16 oz (2 cups) of hydrogen peroxide (6% concentration works best) Higher concentrations yield better eruptions.
- 1 packet 1 packet of dry yeast Acts as a catalyst.
- 3 tbsp 3 tbsp warm water To activate the yeast.
- 2-3 tbsp Dish soap Creates the foam.
- as needed drops Food coloring (optional) For colorful foam.
Additional Materials
- 1 count A clean plastic bottle or container For containing the reaction.
- 1 count Tray or large pan To catch overflow.
- 1 count Safety goggles For eye protection.
- 1 count Spoon or stir stick For mixing.
Instructions
Preparation
- In a clean container, add 16 oz of hydrogen peroxide. This will be the base of your reaction.
- Squeeze in 2-3 tablespoons of dish soap and mix gently. This will create the foam.
- If you want, add a few drops of food coloring to make colorful foam. Swirl it gently to mix.
- In a small bowl, combine 1 packet of dry yeast with 3 tablespoons of warm water. Stir for about 30 seconds to activate the yeast.
- Pour the activated yeast mixture into the container with hydrogen peroxide.
- Step back and watch the astonishing reaction unfold as foam erupts out of the container!
Notes
Temperature matters: Using warm hydrogen peroxide can speed up the reaction. Experiment with colors and scents to enhance the experience. Always conduct the experiment with supervision, especially with children.
