There are many versions of the “Elephant Toothpaste” science demonstration on-line.

When conducting an experiment, you could decide to change one component. For example, you could use more or less yeast (Mrs. Lanman used one packet, which is about 1 tablespoon in about 1/3 cup of water). Or you could change the strength of the hydrogen peroxide. Make a prediction about what you think will happen when you change one component. Then conduct the experiment and see what actually happens. Was your prediction correct? You could keep a chart of results based on the component you changed each time you do the experiment. Remember, always conduct science experiments with adult supervision.
