This is a creative clay with flash! Make several batches in different colors.
I/2 cup cornstarch
3/4 cup cold water
1 tablespoon food coloring
Pour the water and Food coloring into a medium-sized pan. Stir in the salt and cornstarch. Cook over medium heat, stirring constantly until the mixture thickens and gathers together. Take the lump of dough out and wrap in a paper towel. When it is cool, knead for a few minutes. Use as you would any modeling clay or playdough. This dough keeps well in a plastic zip-lock bag in the refrigerator.
