What you will need:

2 cups of plain flour
2 cups of water with black and blue food coloring
1 Tbsp. of cooking oil
1 Tbsp. cream of tartar
1 cup of salt
INSTRUCTIONS:
Mix liquid ingredients in a large pan. (FYI: I found black food coloring in a large size at Big Lots – so I added the entire bottle!  I added a small bottle of blue food coloring.  It made the dough so deep and rich!)  Begin to heat liquids.
In a separate bowl mix dry ingredients.  Add to the heating liquids.   Stir until the dough gathers and thickens.  Cook until it gets that sheen to it.  Let it cool slightly and then knead to bring proper consistency.  Store in plastic container.
I put glitter on the table for the children to push into the playdough – creating the galaxy!
I put out an assortment of items for the children to create little space scenes.
