Elephant Toothpaste Demonstration

The video tutorial demonstrates the elephant toothpaste experiment, detailing the materials needed, the chemical reaction involved, and the role of yeast as a catalyst. It emphasizes safety precautions, such as wearing goggles, and provides a step-by-step guide to conducting the experiment. The tutorial also explores variations using different strengths of hydrogen peroxide, highlighting how the reaction speed increases with stronger concentrations. Observations are made on how the reaction can resemble either an ice cream cone or toothpaste, depending on the setup.
