The Great Elephant Toothpaste Experiment! | Summer Experiments | SciShow Kids

The video explores the concept of mixtures and chemical changes using a fruit salad and a fun experiment. It begins with a discussion about favorite fruits for a fruit salad, highlighting that mixing fruits doesn't change their properties. The video then introduces chemical changes, where mixed substances form something new, demonstrated through an experiment creating a foamy substance resembling toothpaste. Safety precautions are emphasized, and the experiment involves mixing yeast, warm water, dish soap, and hydrogen peroxide. Observations reveal a chemical reaction, evidenced by foam and heat, illustrating irreversible changes, unlike reversible ones like freezing and melting water.
