Watch: Elephant toothpaste balloon experiment - online

A person wearing protective gloves conducts an elephant toothpaste experiment where the chemical reaction takes place inside a large balloon. The experiment involves mixing hydrogen peroxide with a catalyst, creating a rapid foaming reaction that inflates and fills the balloon with expanding foam. The balloon grows dramatically as the chemical reaction produces massive amounts of foam, demonstrating the power of the catalytic decomposition reaction in a contained environment. The foam-filled balloon eventually becomes too large to contain the reaction, creating an impressive visual demonstration of this classic chemistry experiment.
