Elephant Toothpaste
Reacting Agents
Hydrogen peroxide is a relatively unstable compound and slowly breaks down into water and oxygen on its own. This kind of change is a chemical reaction called decomposition. With the aid of a catalyst called catalase which is produced by the yeast, the decomposition greatly speeds up.

Decomposition Of
Hydrogen Peroxide
Hydrogen Peroxide
The higher the concentration listed on the bottle, the more hydrogen peroxide molecules and the fewer water molecules it will contain
The chemical formula for hydrogen peroxide is H₂O₂. which is similar to the chemical formula for water, which is H₂0, except that Hydrogen peroxide has an extra "O", oxygen
Hydrogen peroxide is a relatively unstable compound and breaks down on its own into water and oxygen over time.
A catalyst is a substance that activates a chemical reaction but isn't consumed in the reaction. In my experiment the catalyst is catalase, which is produced by activated yeast.
The catalase from mixed yeast in hydrogen peroxide breaks one of the oxygen atoms off of each hydrogen peroxide molecule, leaving me with one oxygen atom for each HP molecule.
Oxygen atoms are naturally diatomic so single atoms attach to each other creating O₂ gas which floats out of the solution.
The large number of escaping oxygen bubble that are produced by the catalyzed breakdown of hydrogen peroxide become trapped in the dish soap, producing large amounts of foam also know as Elephant Toothpaste
