Materials Needed:

  • 1 cup of water
  • 1.5 to 2 cups cornstarch
  • A small amount of natural food coloring (optional)


  1. Start with the water in a bowl and add the cornstarch a bit at a time.
  2. Keep stirring until it has a gooey consistency. You may want to use your hands.
  3. When the Oobleck is just right, slowly add food coloring (if you want).
  4. Add small amounts of cornstarch or water as needed to achieve a consistency similar to pancake batter.
  5. Have fun experimenting! You can slowly dip your hand into it like a liquid, but if you squeeze it, it will become a solid.

Notes: Utilize a paint smock and table covering to avoid potential staining.
