PSCI: Yeast & Peroxide

Our classroom version of the classic "Elephant's Toothpaste" reaction catalyzing the decomposition of hydrogen peroxide using yeast. We use less soap (just a drop) and 3% peroxide (easier and cheaper to get), which produces larger bubbles that are easier to ignite with a wooden splint to show that the reaction produced oxygen.
