I don’t know if there’s a simpler lab out there that’s more fun as this one.  Here’s what you need:


  • Cornstarch
  • Water
  • Food Coloring (optional)


  • Add 2 parts cornstarch to 1 part water and a few drops of food coloring to a bowl
  • Mix with your hands until all ingredients are combined
  • Have fun exploring Oobleck!

Oobleck is fun for ALL ages.  Try conducting a few tests on it.  What happens when you apply pressure (hit with your fist or finger)?  Is it a liquid or a solid?  Try it!  You won’t be disappointed!
