How To Make Oobleck Recipe - Non Newtonian Fluid (2024)

Learn how to make Oobleck using this simple Oobleck Recipe. This post includes a non Newtonian Fluid Recipe that is one of the coolest science experiments for kids. It’s an exercise in Non-Newtonian fluids, but it’s also tons of fun to squish and play with. If you’re looking for a totally cool Oobleck recipe for kids of all ages (including those at heart) , you’re going to love this!

Crush the oobleck and it turns into a hard ball in your hands. But release your hand, and the oobleck oozes out like slime!

This time, we made our Non Newtonian fluid recipeeven more fun by making it in bright colors and using utensils that bring the experiment to life!

Make the wild oobleck with the colors we did, yellow, orange, blue, and pink, or pick your own favorite colors to try!

Just be careful, it’s easy to end up with brown goo if you add too many colors at once.

How To Make Oobleck

Making oobleck is one of our favorite science activities. It’s similar to slime in that it’s a fun sensory experience, but it’s even more fun because it has properties of a liquid and a solid. Non-Newtonian fluids are a lot of fun to play with, and this version is so colorful you can’t help but love it!

We make this and play with it all times of the year and it’s always a ton of fun. It’s a great sensory activity for children that never gets old.

While it might be just a little bit messy (okay, maybe a lot..), it’s worth it every single time. The kids play with this for hours and always have a ton of fun.

Is oobleck a solid or a liquid?

This is what makes this Non Newtonian Fluid Oobleck Recipe so cool! It’s actually a combination of both a solid and a liquid and that’s just part of the fun appeal!

What is a non newtonian fluid?

If you’re a science fan, you’ve probably heard of non newtonian fluid. A non newtonian fluid is one that doesn’t follow the laws and rules of Newton’s viscosity. In fact, it means that it changes shape and structure to be either a liquid or a solid.

Oobleck recipe ingredients:

How To Make Oobleck Recipe - Non Newtonian Fluid (3)

You will need 4 bowls for this activity.

In each bowl, add:

  • 1 cup of corn starch
  • A squirt of food coloring
  • Water

Add just enough water so that the cornstarch mixes, but not enough that it’s runny. If you have trouble stirring it, but it oozes back together once you remove the fork, it’s a perfect consistency. This part takes a little experimentation to get it right. Add your oobleck to the tray and play!

You can watch this video to learn more about how to make oobleck:

I don’t always use food coloring when making Oobleck. You can check out my post on how to make goop with cornstarch and water post to see what it looks like.

Who knew that mixing cornstarch and water (and a few other ingredients!) could be so much fun! If you are looking for more ways to incorporate oobleck, check out

See what happens when you place the oobleck on different objects, like forks, spoons, slotted spoons, colanders, and anything else you have lying around.

Using different objects will show your children how it moves from item to item. Use this as an opportunity to talk about how objects can mold and change shape easily when they need to. Think of it like an oobleck experiment and talk about the different and various outcomes.

You can even have your children write down their hypotheses and what they think will happen and then compare their notes to watch actually happens as well. This oobleck Science experiment allows you to take into consideration many fun ideas and see which ones are true.

But be warned, this oobleck recipe is extremely messy. You may want to do this activity outside.

This cornstarch and water experiment can also be used to discuss the color mixing theory. The oobleck colors mix quickly, so be careful not to add too much or you’ll end up with a brown goo. If you want to avoid this altogether, just stick to playing with one color at a time, or max two colors.

Can you get the colorful oobleck to combine and make secondary colors? What other colors can you make?

I hope you try this recipe and learned how to make oobleck. It really is something worth checking out. One of the best parts of making slime is the estimation of ingredients and learning how to get it to the right consistency. Teach your kids how to make oobleck and they can estimate how much water vs cornstarch to put in too!

Also, check out our fun science experiments for kids or create some calm down jars.
