Kids can spend hours with play dough when they make it themselves. Make several batches of this and color each one a different color. This variation feels nice and silky, and, if properly stored, stays soft for a very long time. 

Makes about 1 cup of play dough 

1 cup flour (gluten FREE)
1/2 cup salt 
2 teaspoons cream of tartar 
2 tablespoons organic coconut oil 
1 cup water 
A few drops of organic food coloring.  

Put all the ingredients, including the food coloring, in a saucepan and cook, stirring constantly, over medium heat until mixture thickens and holds together in a mass. Remove pan from heat and let the dough cool. Turn out onto a work surface and knead several times until soft, pliable and smooth. Use immediately or store in an airtight plastic container.
