Fun-Sized Friday: Explore Oobleck



To explore concepts of science by observing states of matter.


  • 1/2 cup of corn starch

  • 1/4 - 1/2 cup of water

  • food coloring


  1. Put three drops of food coloring in the water and stir it up.

  2. Dump the cornstarch into a bowl.

  3. Slowly add the water. (It gets really hard to mix, so young children will need help.)

  4. Continue mixing until it reaches a consistency that feels like a solid when you hit it with your fist, but that you can pick up and it slowly oozes out of your hand.


Oobleck is a really fun and simple science experiment for anyone to try with their kid. If you have a younger child, it is fun to let the kids play with it and feel the weird texture that is formed. If you have an older child, it’s a great chance to do a science experiment over the states of matter. If you are an adult…it’s just plain fun.

Oobleck has been made popular by the Dr. Seuss book “Bartholomew and the Oobleck.” It is very easy to make and takes a matter of minutes with just a couple of ingredients, making it the ideal experiment or fun activity to do with your child. Our kids really enjoyed playing with it. We did a quick explanation of the states of matter: solid, liquid, and gas. It gave the kids an idea of how strange oobleck is, since it acts like a solid and a liquid.

It’s very hard to explain how it feels without trying it for yourself but if you try to hit it with your hand or a flat object it acts like a solid and stays firm; however, you can easily put your hand into it and grasp it and it suddenly turns into a liquid and pours out of your hand.

Be sure to check out our video to see our kids making and playing with oobleck. Now go out and have some fun making oobleck and exploring life!
