Instructions
Pour 1/4 cup cornstarch into a disposable plastic bowl and sift it with your fingers or a fork to break up the particles. Mix in 4 oz. (1/2 cup) white glue until fully combined. Combine 1/4 cup warm water and 1/2 tsp. Borax in a separate bowl. Add a few drops food coloring; add more for vibrant goop colors. Combine the Borax mixture with the cornstarch/glue and stir with a wooden spoon for three minutes. Remove goop from the bowl and store in an airtight container.
Make an organic version of this recipe without Borax. Combine 1/2 cup water and 2 cups cornstarch in a disposable plastic bowl. Add a few drops of food coloring, if desired, to create a more liquid goop. Goop with food coloring should be used only on a surface protected by plastic or newspaper to reduce staining.
Prepare Silly-Goop by mixing 2 cups cornflour with 1 cup warm water. Pour the mixture into a saucepan and cook over low heat. Slowly add 3 cups flour, stirring constantly. As the mixture heats, slowly add an additional cup of water, stirring well. Cool the goop until it can be handled. Remove from the pan onto a floured surface. Apply flour to your hands and knead the goop until it is no longer sticky. Store in a plastic storage bag.
