2 1/2 c. flour
1/2 c. salt
1 tbsp. alum
3 tbsp. corn oil
30 drops food coloring
2 c. boiling water

Mix flour, salt and alum together in a bowl. Add oil and colored hot water. Mix everything until it is cool enough for you to use. If clay dries out, wrap in a damp cloth, put in a plastic bag and let stand for a couple of days.

Note: This clay stays soft so it can be reused.
