3 and 4 GRADERS

3rd and 4th grade children 👫created a giant foaming reaction by using science 🧬 experiment!
With just a few ingredients they made something that looks like foamy toothpaste being squeezed from a tube—but so big that it looks almost fit for an elephant🐘!

So what happens❓

When hydrogen peroxide breaks down, it turns into oxygen (O2) and water (H2O). Normally this breakdown happens very slowly. But they made the reaction happen faster! How? By adding a catalyst. Yeast is an organism that contains a special chemical called catalase that can act as a catalyst to help break down hydrogen peroxide. Catalase is present in almost all living things that are exposed to oxygen, and it helps them break down naturally occurring hydrogen peroxide. 
This means that if you mix yeast with hydrogen peroxide, the hydrogen peroxide will rapidly break down into water and oxygen gas. The oxygen gas forms bubbles. These bubbles would usually escape from the liquid and pop quickly. But adding a little dish soap provides additional surface tension, allowing the bubbles to get trapped and creating lots of foam.
Do you need any toothpaste Mr Elephant 🐘? 😁😁😁
