Get a good working surface. You
will want a surface that can get messy, because this will get very
messy.
Get a container. You will want a
fairly large container, such as a 32oz soda bottle
Form the outside of the
volcano. You can make the outside from clay,
playdough, dirt, soil, or tin foil. Paint it brown and black to
make it look more realistic. Let it set until it is all dry.
Pour your hydrogen peroxide. Get a
bottle of hydrogen peroxide from a beauty supply store. You will
need a 6% solution (usually labeled as “20-volume”). Pour half a
cup of the hydrogen peroxide into the container in your
volcano.
Be careful with hydrogen peroxide.
You hurt yourself if you touch it too much or get it in your eyes.
Only adults should handle hydrogen peroxide.
If you want to make the reaction
even more dramatic, use a 30% solution of hydrogen peroxide. This
may be more difficult to find, however.
Mix in soap and food coloring. Mix
in at least six drops of red food coloring and two drops of yellow
food coloring. Then mix in about two tablespoons of dish soap.
Mix yeast. Get a tablespoon of dry
yeast and mix it with 3 tablespoons of water in a separate small
cup.
Pour the yeast. Pour the yeast
mixture into the volcano.
