on your birthday morning, you're making 5 lbs of play-doh!
This is the best recipe I've found so far:
BASIC PLAY CLAY RECIPE 1 cup flour 1 tbsp. vegetable oil 1 cup water 1/2 cup salt 2 tsp. cream of tartar Heat, stirring constantly, until ball forms. Knead. Store in airtight container or plastic bag. Makes about 4 portions.
Note: I added food coloring directly into the water for brighter colors.
