Galaxy Oobleck

Oobleck is not a liquid or a solid, it’s a non-newtonian fluid. That means it doesn’t follow the rules of Newton’s law of viscosity. Oobleck is great for teaching kids all about states of matter. When it’s dry, oobleck is solid. When it’s wet, oobleck is liquid.

Plus, it’s a lot of fun to play with too. 

With the outer space colors in galaxy oobleck, you can use this experiment in a space-themed unit study or add some fun to a Star Wars birthday party. It’s fun also a fun experiment for exploring states of matter.

How Do You Make Oobleck?

Making your very own galaxy oobleck is easy. You can get the kids involved in the whole process! Check out my original Oobleck Recipe to make your very own oobleck base. The ingredients are corn starch and water, so it’s safe for young children who might be tempted to taste their oobleck. 

To make galaxy oobleck, you’ll need to separate your oobleck into three different bowls or jars. Then, add pink food coloring to one, purple food coloring to another, and blue food coloring to the last container of oobleck. Mixing these three colors will give you a fun galaxy color palette your kids can have lots of fun exploring.

Want to add more out of this world fun to your galaxy oobleck mix? You can add glitter (edible glitter for kids that might taste their oobleck). The glitter will look like stars sparkling in your galaxy oobleck.

Another fun idea is to add bouncy ball “planets” for your kids to explore and learn about the solar system as they engage in this fun sensory science experiment.

How to Make Galaxy Oobleck

The proportions listed don’t need to be exact, so please feel free to add a little more or less depending on the exact consistency you would like.

Oobleck Ingredients

½ cup of corn starch
About 2 to 3 tablespoons of water
Color of choice, we used a Wilton gel color set
Optional: glitter

Instructions

  • Add the cornstarch and coloring to each of your jars.
  • One at a time, add water to the jars and mix until fully combined. I found the mixture to be fairly dry and crumbly at first (see image), but with just a little more water it all came together.
  • The mixture will be very stiff and a little challenging to mix, great for old children but little ones will need some help to get to the correct consistency.
  • Use the end of the spoon to scoop down to the very bottom of the jar to ensure all parts are incorporated.
  • Once the oobleck is fully mixed together you can transfer it out into your tray. We added the glitter to it once it was out on the tray.

This Oobleck is a ton of fun to explore and play with!

Learning About States of Matter with Oobleck

Teaching lessons about states of matter is one cool way to use this exciting galaxy oobleck science experiment. I like to begin by encouraging my kids to observe and experiment with the oobleck and talk about what they see and feel.

Galaxy oobleck is a great way to teach your kids all about solids and liquids because it’s both! 

You can combine a lesson on the states of matter with your outer space unit study. Talk about how our galaxy is comprised of solids (planets, asteroids, stars), gas (the atmosphere, gas giants like Jupiter and Saturn), and even water (clouds of water vapor, water molecultes on the moon. 

By the end of the lesson, your kids will have a good grasp on the three states of matter. Plus, they’ll have some hands-on learning fun to help them remember all the cool things they learned about matter in space.
