Create OOBLECK | Easy Science Experiments for Kids

Kids love getting messy and reviewing their states of matter knowledge in this messy, yet fun, hands on science demonstration. Oobleck, a non-Newtonian fluid, is also a fictional green precipitation invented by children’s author Dr. Seuss in the book Bartholomew and the Oobleck. After reading the story, explain to your student or group of students that you will be creating the icky rain called Oobleck and exploring its properties.

Materials and Recipe

Oobleck is easy to create. Simply mix 2-parts corn starch and 1-part water, depending on the amount you want to create. For one demonstration, you will need to mix 2 cups of corn starch and 1 cup of water.

Suggested Activities

  • Squeeze the substance.
  • Let the substance drip from your hand.
  • Try to pound the substance with your fist.
  • Try taking a spoon out of the substance.
  • Try mixing the substance with a spoon.
  • Challenge your students to take a stance on the question: What state of matter is Oobleck? Make sure they can defend their answers with evidence.
