What is Oobleck?

Bartholomew and the Oobleck: (Caldecott Honor Book) (Classic Seuss)                     

Making Oobleck is a perfect activity when studying Matter because it presents characteristics of a liquid and a solid. Plus, it's an EASY, MESSY, and FUN activity which kids LOVE!

But, what is Oobleck???
Scientists call Oobleck a non-newtonian fluid because it acts like a liquid when you pour it but it acts like a solid when a force acts on it.


  • measuring cup
  • 1 cup water
  • 1 1/2 cups cornstarch
  • food coloring (few drops) - optional
  • spoons/mixing sticks
  • plastic containers
  • small zip-lock plastic bag
  • old clothes or aprons (suggested)
  • plastic tablecloth or other covering (suggested)
  • warm water and paper towels (for clean-up)
  • other cleaning supplies as needed
You may need more cornstarch or water than what is listed above. 


  • Review the states of matter especially liquids and solids.
  • Have children observe and discuss the materials needed for the activity.
  • Pour the cornstarch into the bowl. Observe.
  • Add the water slowly, stir, and mix. Observe.
  • Students can finish mixing the Oobleck with their  hands.
  • Have students describe how it feels and discuss its characteristics.
  • Try to pour the Oobleck into another container.
  • Students could store the Oobleck in a plastic bag to use later.
  • Wash all containers, utensils, hands, etc. 
  • Do NOT put any Oobleck in the drains!


    • Read Bartholomew and the Oobleck by Dr. Suess.
    • Compare and contrast the Oobleck in the book to the Oobleck the kids made.
