video Easy Elephants Toothpaste Experiment
Fun With Foam
Foam is fun! Check out this video to see our Fantastic Foamy Fountain in action. The experiment uses Hydrogen peroxide and dry yeast. Hydrogen peroxide is similar to water but it has an extra oxygen atom. This makes it more dangerous and only adults should handle the hydrogen peroxide.
When you add the yeast, it acts as a catalyst (a helper) to release the extra oxygen gas and the soap helps to create all the foam. Try it out yourself!
The second experiment with the giant foam eruption at the end used a more powerful hyrogen peroxide and a different chemical for a catalyst. The reaction happens very fast and gives off quite a bit of heat. It's pure foam fun! I mean pure science.

Can I use MnO2 (Manganese dioxide) as an catalyst?

IF the bubbles are filled with oxygen then i bet you could light them on fire!

oxygen doenst burn, it only makes things more flamable in an oxygen rich atmo, so by the time the "foam" has expanded enough the o2 will have dissapated

so what is the chemical catalyst in the giant eruption?

The catalyst is an enyme in the yeast called catalase. It also occurs in the human body for destroying free radicals created by cell processes

Hi Karossil, The catalyst in the second experiment was a sodium iodide solution.
