In a bowl, mix 1 cup flour, 1/2 cup salt, 1 teaspoon alum (available
in grocery or drugstores) and 2 tablespoons vegetable oil.
Place 1/2 cup water in a separate container. Add 8-10 drops of
food coloring and stir.
Add water to the other ingredients a little bit at a time, mixing
well between additions, until the stuff feels like dough; you
may not need all the water.
Mix some baking soda into the dough, adding a little water if
it is dry.
Mold dough into whatever monster shape you'd like. Hold monster
over a sink or take outside. Pour some vinegar over your monsters.
They will sizzle and dissolve!
