Elephant Toothpaste Experiment

Ever wonder why it’s called elephant toothpaste? When yeast breaks down hydrogen peroxide, it creates a huge rush of bubbles that look like a giant squirt of toothpaste—big enough for an elephant! The cool part is that the same yeast you use to bake bread is at work here too. In bread, yeast eats sugar and makes bubbles that puff the dough up soft and fluffy. In this experiment, it makes bubbles in a totally different way, but the idea is the same—yeast is a bubble maker.
