Ingredients Method

Ingredients
  

  • 2 cups Cornstarch or alternative starch like Tapioca
  • 1 cup Warm Water
  • 3 –4 drops Food Coloring optional, for vibrant color

Method
 

  1. Set Up: Grab a wide, shallow mixing bowl, baking sheet, or plastic tray to contain the play area and prevent kitchen mess.
  2. Color the Water: Add 3–4 drops of food coloring directly into your 1 cup of warm water and stir until the color is fully blended.
  3. Combine: Pour 2 cups of dry cornstarch into your mixing bowl. Slowly drizzle the colored water over the powder.
  4. Mix: Use your hands or a sturdy spoon to mix gently. At first, you will feel high resistance—keep turning it over until all dry powder disappears.
  5. The Perfect Test: Scoop some up in your hand; it should melt like liquid syrup. Now, smack the surface with your open palm—if your hand bounces off without splashing, your Oobleck recipe is perfect!
