Sand Clay -
(Reprinted from �Science Arts� by Mary Ann Kohl and Jean Potter)
1 cup fine beach sand
� cup (125 ml) cornstarch
� cup (125 ml) (and maybe a little more) boiling water
double boiler
stove
flat pan or cookie sheet
ADULT HELP
An adult can mix the fine beach sand and cornstarch thoroughly in the top of the double boiler on
the stove.  Next, an adult can pour in the boiling water and mix well.  Cook this sand clay mixture in the double boiler briefly until thickened.  (If too thick, ad a little more boiling water.) Cool the sand clay a little bit before modeling.  Create any clay designs or objects.  Next, place the Sand Clay object on a flat pan in a 275 degree Fahrenheit (140 deg. Celsius) oven until dry.  Or, dry the Sand Clay object for several days on a shelf or table.
BONDING: Cornstarch is used in cooking as a thickener.  When cornstarch is mixed with sand
and water and heated on the stove, the cornstarch woks like a cement and thickens the mixture,
BONDING the ingredients as a modeling clay which is unlike sand alone or cornstarch alone.  When an object made from Sand Clay is dried in the oven or left to dry on a shelf, the object dries to a rock-hard consistency.

Soap Crayons -
1 cup soap flakes
food coloring
2 tablespoons hot water
large bowl and several small bowls
plastic ice-cube trays or molds.
Put soap flakes in a large bowl and drop the hot water into the soap flakes, stirring constantly.  The mixture will be extremely thick and hard to stir.  Spoon some of the soap into each of the small bowls and color each separately, adding the color by drops until the soap has the consistency of a very thick paste.  Press spoonfuls of the soap into your molds and set the crayons in a dry place to harden.  They should take a few days to a week to dry completely.  When dry, remove from the molds and allow to dry for a few more days before using.  Yields about 20 crayons.
