Elephant toothpaste

First, gather the supplies.

But before you add the yeast, you toss in some dish soap, which increases the surface tension across the hydrogen peroxide. Then, when the yeast causes oxygen to break off and form bubbles, they won’t burst right away—and the foamy concoction will pour forth from its receptacle.

The chemical formula for hydrogen peroxide is H2O2 which can be found in various concentrations, usually 3%, that you can buy at a pharmacy. Hydrogen peroxide kills bacteria, and it has been used as an antiseptic for about 200 years. Since hydrogen peroxide is relatively unstable when exposed to light, it is usually stored in dark brown containers since light decomposes hydrogen peroxide into oxygen (O2) and water (H2O) while generating heat. Generally, this reaction happens very slowly, but certain compounds, called catalysts, can make the decomposition happen faster. For example, yeast or sodium iodide can catalyze the decomposition of hydrogen peroxide. In yeast, an enzyme called catalase functions as the catalyst.
