Goo, Goo, and more Goo for You!

Things you will need:
-A Small Plastic Bottle
-Hydrogen Peroxide (20 or 40 Volume)
What you need to do:
With gloves and safety glasses on, pour ½ cup of your hydrogen peroxide into
the bottle. Be careful because you do not want to get this on your skin.
Add about 8 drops of food coloring and 1 tablespoon of liquid dish soap.
Swirl the mixture around just a bit. In a separate container combine 3
tablespoons of warm water with a packet of yeast and mix for about 30
seconds. Pour the yeast in the bottle and watch the goo grow!
What is going on here:
Hydrogen peroxide decomposes into water and oxygen. This is an enzyme
controlled decomposition reaction where enzymes in the yeast assist in the
decomposition of the hydrogen peroxide. Hydrogen peroxide is an unstable
substance , meaning that it will break up over time into water and
oxygen. We are adding a catalyst to speed up this reaction. Oxygen is
caught up in the soapy mixture and goo is born. This is also an
exothermic reaction so some heat is produced.
