Elephant Toothpaste
MATERIALS NEEDED:
HOW TO DO:
How did that happened?
Dishwashing liquid
Yeast
Ready the Ingredients!!
MIX
1/2 Cup of Hydrogen Peroxide
Pour the yeast mixture in the graduated cylinder...
AND BE AMAZED!!!
The reaction is summarized by this formula:
2 H2O2 --> 2 H2O + 02.
Hydrogen peroxide (H2O2) naturally breaks down into water and oxygen.
Dish soap catches the oxygen and makes bigger bubbles and the food coloring makes it look cool.

Hydrogen Peroxide
Colored Dyes /
Food color
and
WATER
Mix
2 tablespoons warm water
1 teaspoon yeast
in a container.
4-5 of drops food coloring
A squirt of dish soap
in graduated
cylinder
It is stored in opaque
containers
to help
slow down
this process.
Catalase
(an enzyme in all living things, including yeast) speeds up the reaction.
The foam and
bottle feel warm
because the
reaction is
exothermic--it
releases energy as heat.
