Playdough

This is the recipe my mom used for "Over the Rainbow Preschool" in the 1980s.

2 cups flour
2 c water
1 c salt
1/2 c cornstarch
1 T alum
1 T oil

Mix all together.  Cook and stir over meduim hear until it begins to thicken and hold together.  It looks lumpy, but kneads out smooth.

Remove from head and knead until smooth.  Seperate and add food coloring to each section--kenading well.

Store in sealed bag or container for 2 months or so in refrigerator.
