π₯ Chemistry in action at STEM Skool!
Last week, students explored physical and chemical changes with two crowd favorites: Diet Coke + Mentos and Elephant Toothpaste.
Both produce spectacular bursts of gas, but the science behind them is completely different. Diet Coke + Mentos demonstrates a physical process called nucleation, while Elephant Toothpaste creates a warm, foamy eruption through an exothermic chemical decomposition reaction.
Big reactions. Real chemistry. Lots of excitement.
Just another Friday in Chemistry: Food, Art, and Human Performance at STEM Skool!
