Elephant toothpaste is a very easy and funny science experiment, which results in a rapid eruption of huge amount of foam. In the past few years, I have performed this experiment with my kids over 50 times. Things we need: Level 1: beginner level -10% hydrogen peroxide -food coloring -dish soap -yeast Level2: Intermediate level -20% hydrogen peroxide* -food coloring -dish soap -saturated potassium iodide Level3: ultimate level -35% hydrogen peroxide* -food coloring -dish soap -saturated potassium iodide *20% or above hydrogen peroxide is highly corrosive, please wear glove when you deal with it Elephant toothpaste is the decomposition process of hydrogen peroxide, while yeast / potassium iodide works as a catalyst to break down the hydrogen peroxide into oxygen and water. Soap will then mixed with the oxygen and water, which turn into foam. #elephanttoothpaste #chemistry #chemicalreaction #science #scienceexperiment #interesting #experiment #reaction #chemical #scienceproject #sciencefacts #sciencefairideas #sciencefun 0:00 Introduction 0:11 Beginner level (For Kids) 0:55 Intermediate level 1:55 Ultimate level
