Add the flour, cream of tartar, salt, and 3 tablespoons cooking oil to a large pot. Whisk together. Add water and whisk until smooth. Cook over medium heat, stirring constantly, until the dough forms a soft ball. Be sure not to overcook--it will be too dry. Remove from heat and then scrape together the mixture into a ball. Place in a Ziploc bag or cover with plastic wrap and allow to cool slightly.

Divide into portions and use food coloring to color as desired (if you want to make it all the same color, add the food coloring with the water.) For very vibrant colors, use more than you think you'll need. When done playing with the dough, store in airtight containers or Ziploc bags.
