Play Dough

Playdoh or Play dough - however you spell it it's an essential in a Junior classroom.
We use it in maths, literacy and general play.

Here's the recipe for a useful cooked play dough.

1 cup white flour            1/2 cup salt                         1 cup cold water
1 tbsp oil                         2 tsp cream of tartar           food colouring

Stir all ingredients together.
Cook them over a low heat, stirring occasionally, for 3-5 minutes.
You will be able to stir it into a sticky dough when it is close to being ready.
It is ready when it is still sticky but seems to be drying out a bit. 
The dough will continue to dry as it cools down. 

Cool and store in an airtight container.
