Wow! Today in science we made a fantastic foamy fountain. It was pretty amazing. Here is a video if you would like to see what it looked like.
What happened???
When the liquids were mixed together they turned into a foam.
The foam went up the cylinder like an elevator.
Bubbly stated to form in the foamy mixture.
The foam slowly spilled over the cylinder and travelled down the sides.
Why do we think this happened???
There was a reaction between the yeast and the hydrogen peroxide.
The yeast made the foamy mixture rise.
Why did it actually happen???
Each tiny foam bubble is filled with oxygen. The yeast acted as a helper and removed the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots of bubbles!
The foam it created was warm and bubbly because of all the mixtures that were mixed together.
If you would like to do this experiment you will need:
2 measuring cylinders (1 large and 1 small)
1 tablespoon of dishwashing liquid
1/2 cup of hydrogen peroxide
3 tablespoons of warm water
1 tablespoon of dried yeast
Gloves for each person doing the experiment to wear
1 spoon or stick to stir
