Easy Elephants Toothpaste Experiment
Intro: 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.

A long time ago this experiment was done using real elephant; but now we have to use fake elephant.

And burn everything to the ground :P

We actually have some 30 percent in our basement. I might do this.

In another article about this, meant for science classes, they suggested an experiment to demonstrate your point. Light a match and then blow it out. Right away (before the match can cool), hold the match just above the foam - the influx of oxygen should reignite the match if there's any ember left in it. I imagine this works better if you hold it above the tube the foam is flowing out of.

Hydrogen Peroxide is H202 (two hydrogen atoms, 2 oxygen atoms). The yeast acts as a catalyst, separating the H202 into H2O + O (it splits into water and oxygen). This reaction also releases heat.
All this heat, water, and oxygen creates steam. Because you added dish soap, the rising steam makes bubbles (foam).

The elephantoothpast is the experiment for ever one 5 throw 30 year olds.
