Kids of all ages love moulding Play-Doh into shapes, characters and food. However, everyone leaves a chunk of Play-Doh out once in awhile, and once exposed to air, the clay dries out fairly quickly and becomes hard to play with. Don't toss out that old, dry Play-Doh yet. The clay can be easily restored to its former glory with a few simple ideas.
Boil water in a teapot or sauce pan.
Grab the Play-Doh and place it into the steam to let the moisture hit it.
Knead the Play-Doh until it is restored. Repeat the steaming if necessary until the Play-Doh is malleable again.
Lay the Play-Doh on a work surface.
Add water to the clay, one drop at a time. Knead the water into the clay with your hands.
Add water in small amounts until the Play-Doh has been restored.
Drip enough water onto a paper towel to make it slightly damp but not soaking wet.
Put the Play-Doh in the paper towel and wrap it up.
Place the wrapped Play-Doh into a plastic container and let it sit that way overnight.
