My boys just love when I make this. I have tried a few different recipes and this one is by far the best. It is incredibly easy and once you try it you will never spend a dollar buying play dough. It lasts for a long time at room temperature if sealed in an airtight plastic baggie or container.
All you need:
2 Cups All Purpose Flour
2 Tbsp Cream of Tarter
1 Cup Salt
2 Tbsp Oil
2 Cups Boiling water
Add first four ingredients together in a large bowl
Pour the boiling water over it all and stir! It will come together just keep stirring.
Split it up and add food coloring if you want to (wear gloves unless you want tie dye hands for the day)
Let the kids play with it and make sure you put it into a plastic bag when your done so you have it for next time.
