Ever wonder how to make black playdough? It's easy, with the right ingredients, to make soft, squishy, totally black playdough. Perfect for Halloween!
In a large pot, add flour, salt, and cream of tartar. Stir with a whisk until thoroughly mixed.
Measure 2 cups of hot water and add the black food coloring. Mix until color is fully dissolved.
Add black water, vegetable oil, and glycerin to flour mixture in pot. Mix thoroughly with a spatula.
Cook over medium heat, stirring constantly, until almost playdough texture. Do not overcook as playdough continues to cook a bit and will get dry if overcooked. Remove from heat.
Remove playdough from pot and place on a plate. Once playdough is cool enough for an adult to handle, knead well.
Cover with a wet paper towel until cool enough to play with or store. Store in a zipper bag or other air tight container. Store in a cool, dry place.
