What You’ll Need
- 1 cup baking soda
- 1/2 cup cornstarch
- 3/4 cup water
- Measuring cups saucepan, spoon
Equipment
- saucepan
- mixing bowl
Directions
- Stir the baking soda, cornstarch, and water together in a pot.
- Cook over low to medium heat, stirring all the time. Take it off as soon as it pulls away from the pot and looks like mashed potatoes. “Do not overcook!
- Move it to a bowl or baking sheet and let it cool to room temperature, at least half an hour.
- It should be very soft and easy to mold but not sticky; if it sticks, dust the surface with cornstarch.
- Roll it out or shape it by hand; cookie cutters work for ornaments.
- Let it air dry for 3 to 5 days, or bake at 200F for 1 to 1.5 hours, turning it over halfway.
Notes
Wrap unused clay in plastic wrap and keep in a zip bag or airtight container. If pieces won’t stick together, wet the joint with a bit of water.
Safety: NOT edible. Adult does the stovetop cooking; the clay is hot inside right after cooking. Dried pieces are fragile and can break into small bits; keep finished ornaments away from toddlers.
