Transcript of The Science behind 'Elephant Toothpaste'

A clean 16 ounce plastic soda bottle
1/2 cup 20-volume hydrogen peroxide liquid
1 Tablespoon (one packet) of dry yeast
3 Tablespoons of warm water
Liquid dish washing soap
Food coloring
Small cup
Safety goggles
put on safety goggles and carefully pour the hydrogen peroxide into the bottle
Add 8 drops of food coloring into the bottle
Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it
In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.
Pour the yeast water mixture into the bottle and watch reaction!
On a molecular level...
water= H2O
hydrogen peroxide= H2O2

When you add yeast to the mix, the fungi aid in the decomposition of the hydrogen peroxide, stripping off extra oxygen
The extra oxygen becomes a gas -foam
Chemical Change
1. Cannot go back to original state
2. Produces Gas
3. Produce/Consume Solid
4. Change in temperature
What kind of reaction?
Exothermic chemical reaction!
it heats up!

The Experiment
But how does it work?
Toothpaste fit for an Elephant!
The Science behind 'Elephant Toothpaste'
A thick foam quickly shoots out of the bottle
