Equipment

  • Large mixing bowl
  • Spoon or rubber spatula
  • Tray or plate to put under food coloring to prevent spillage
  • Small cups, spoons, or toys for sensory play (optional)
  • Cookie sheet or cutting board (optional)

Ingredients

Instructions

  • Collect your equipment and measure out the ingredients.
  • Pour the cornstarch into a large mixing bowl.
  • Add the food coloring to the water (optional).
  • Slowly add the water to the cornstarch and stir. Mixing is challenging so be patient and mix gently or the mixture will pop over the edge of the mixing bowl. Oh, and you can do some of the mixing with your hands if you want!
  • Stir until the Oobleck ingredients are fully mixed together. The texture will be consistent and gooey. Remember, it is an unusual mixture so will be firm when you squeeze or press it and runny when you stop applying pressure.
  • If the Oobleck mixture is too runny add cornstarch one Tablespoon at a time. If the mixture is too thick add water one Tablespoon at a time.
  • Have fun playing with your Oobleck. Stay over a counter, cookie sheet, or cutting board as the mixture is messy!
