In the video 8-year-old Emma makes the play dough.
The ingredients needed for the play dough are flour, water, salt, oil, cream of tartar, and some food coloring to give it the color.
She places all the ingredients in a pan and mixes them together with a wire whisk. Then she puts the pan on the stove and lets the mixture cook for several minutes until it thickens, whisking it constantly as it cooks.
Next she puts the dough out onto a floured surface and kneads it until all the flour is absorbed. The result is a nice big ball of play dough.
