How can I use the ingredients to make elephant toothpaste?

To make elephant toothpaste, you will need hydrogen peroxide, dish soap, food coloring, and yeast. Mix the hydrogen peroxide and dish soap together in a container. Add a few drops of food coloring for color. In a separate container, mix yeast with warm water. Pour the yeast mixture into the hydrogen peroxide mixture and watch as the foam (elephant toothpaste) grows. Be cautious as the reaction can be vigorous.
