The good thing about the
sponge is that you can cut it to desired shapes.

still
get this at the grocery store, I just
called
to see) and ammonia in a glass jar.\tPour over
the rocks,
being sure to dampen all of them with the mixture.

drop or two of food color and a few drops of bluing on
one
or two of the rocks.

watch it grow.
Add 2 tablespoons each water and ammonia\tafter
two days
