In a medium sized sauce pan, combine flour, salt, kool aid and cream of tartar. 

Mix together. 

Add water and oil. 

Stir over medium heat until the play dough becomes firm and hard to stir. {It will change pretty quickly so watch it close!}

Once it becomes too hard to stir, dump out onto lightly floured counter. 

When the play dough is cool to the touch, knead together until smooth. 

Store in air tight container, in the refrigerator.
