Ewan and I made Play-doh today! Super fun, super easy.
1/4 cup salt
1/2 cup water
1/2 tablespoon oil
1/2 tsp cream of tartar
Stir everything together in a pot on low heat until it turns into a ball of dough. That's it. Then divide to mix in different food coloring. Safe to eat, though I don't recommend it... salty! And the recipe even works without cream of tartar... apparently I'm out. :)
Found the recipe from this Simple Mom blogpost...
