How to Make Oobleck

  • Author: Jean Van't Hul
  • Prep Time: 5 minutes
  • Cook Time: 5 minutes
  • Total Time: 10 minutes


Part art + part science, this fun stuff is also known as goop or sensory goop.




  • 1 1/2 to 2 cups cornstarch
  • 1 cup water
  • Food coloring
  • a large plastic bin (to contain the oobleck while you play)


  1. Whisk the food coloring into the water so that it colors the oobleck evenly.
  2. Then stir in the cornstarch. Start with 1.5 cups and add more if it is too runny.


You’re looking for a consistency that is solid and then runs off when held in your hand.
