Lets Make Play Dough!!! (a chemistry mini project)


In class we made play dough using:
- 1 teaspoon of oil
- 1 cup of flour
- 1 cup of sugar
- 1 cups of water
- couple drops of food coloring

We mixed all of together at high heat and stir the mixture until in becomes more puddy and manageable and then we took it out, coated it with flour to not make it so sticky and then presto, you have play dough!! Now you can make whatever shapes you want with it, a star, a heart, one guy even made a mini tank!!

The chemistry behind it:
Flour is held together by hydrogen bonds, however, using the sugar we were able to transform the molecular structure and cut the hydrogen bonds, creating the dough's new texture of play dough.
