2 cups flour (If using gluten free flour use 2 and a half cups of flour)
2 cups water
1 cup salt
2 tbsps vegetable oil
1 tbsp cream of tartar
You can add any food colouring, paint, glitter or scented oils for interest.
Mix all the ingredients together in a saucepan and stir over a low heat. The dough will thicken to look like mashed potatoes.
Once it comes cleanly away from the sides of the pan and forms a lump in the middle, remove from the heat and allow the dough to cool. If it is still a bit sticky you need to cook it a bit longer - it will end up with the texture of bought play dough.
