Anne, The Making Things Girl, demonstrates how to make play dough. Play dough is almost like clay in that you can bake it so it hardens. Then you can decorate it with things like paint, glitter and rhinestones. To make play dough you will need 2 parts flour, 1 part household salt and 1 part water with 2 tablespoons of olive oil. Mix the ingredients in a mixing machine for one minute. Next, work and knead the dough in a bowl and then on the counter. Knead the dough for a while because it makes the salt react with the oil and it gets very elastic and smooth to work with. Your dough should not be ready to use. After you make your dough projects, bake in the oven at about 284 to 320 degrees Fahrenheit for 2 hours.
