How to Make Oobleck: A Step-by-Step Guide

Greetings, Asensio!

If you’re looking for a fun and unique science experiment to try at home, making oobleck is the perfect activity for you. Not only is it easy to make, but it also has some fascinating properties that will keep you entertained for hours. In this article, we’ll guide you through the process of making oobleck, explain the science behind it, and answer some frequently asked questions. So, let’s get started!

What is Oobleck?

Oobleck is a non-Newtonian fluid, meaning it doesn’t behave like a typical liquid or solid. When you apply force to oobleck, it becomes more solid, but when you release the force, it turns back into a liquid. This strange behavior is due to the properties of the materials used to make it.

Oobleck is made from two simple ingredients: water and cornstarch. When these two materials are combined, they create a unique substance that behaves differently than any other material we encounter in our daily lives. The result is a gooey and messy substance that is lots of fun to play with.

How to Make Oobleck

Now that you have an understanding of what oobleck is, it’s time to make some of your own. Here’s what you’ll need:

Materials Measurements
Cornstarch 1 cup
Water 1/2 cup
Food coloring (optional) A few drops

Step 1: Measure Your Ingredients

Start by measuring out your cornstarch and water into separate containers. You’ll need one cup of cornstarch and half a cup of water.

Step 2: Mix the Ingredients Together

Pour the water into the container with the cornstarch and mix them together. You can use a whisk or a spoon to stir the mixture, but be prepared for it to be difficult to stir at first. Keep stirring until the mixture is well combined and has a gooey, paste-like consistency.

Step 3: Add Food Coloring (optional)

If you want to add some color to your oobleck, now is the time to do so. Add a few drops of food coloring to the mixture and stir it in until the color is evenly distributed.

Step 4: Experiment with Your Oobleck

Once you’ve made your oobleck, it’s time to start experimenting with it. Try applying force to it with your hands or a spoon and see how it behaves. You can also try rolling it into a ball or pouring it onto a surface and watching how it spreads out.

Step 5: Clean Up

Oobleck can be messy, so be sure to clean up any spills or drips as soon as possible. Use warm water and soap to clean any oobleck off of surfaces or clothing.

Frequently Asked Questions

What is the Science behind Oobleck?

The unique properties of oobleck come from its non-Newtonian behavior. When a force is applied to the mixture, the cornstarch particles become packed together, creating a solid-like substance. However, when the force is released, the particles quickly separate again, creating a liquid-like substance.

What Other Materials Can I Add to My Oobleck?

You can experiment with adding different materials to your oobleck to see how they affect its properties. Some common additions include glitter or small beads for texture, or vinegar to create a reaction.

Can I Eat Oobleck?

While oobleck is non-toxic, it’s not meant to be eaten. It’s important to keep it away from your mouth and eyes to avoid any potential health risks.

How Do I Store Oobleck?

Oobleck can dry out quickly, so it’s best to store it in an airtight container. If it starts to dry out, you can add a little bit of water to bring it back to its original consistency.

How Do I Dispose of Oobleck?

Oobleck can be disposed of by throwing it in the trash. It’s important not to pour it down the sink or toilet, as it can cause plumbing issues.

Can I Use Oobleck as a Stress Ball?

Oobleck can be used as a stress ball, but be aware that it may not hold its shape for very long. It’s also important to keep it away from electronic devices, as it can be difficult to clean off.

Is Oobleck Safe for Kids?

Oobleck is generally considered safe for kids to play with, but adult supervision is recommended. It’s important to keep it away from the mouth and eyes, as well as any electronic devices or other objects that could be damaged by the gooey substance.

Can I Make Oobleck in Different Colors?

Yes! You can add food coloring or other materials to your oobleck to change its color. Experiment with different combinations to see what you like best.

What Happens If I Store Oobleck in the Fridge?

Oobleck can be stored in the fridge to help it last longer. However, it may become thicker and more difficult to work with when it’s cold.

Can I Paint with Oobleck?

Oobleck can be used as a type of paint, but be aware that it may not adhere well to certain surfaces. Experiment with different materials to see what works best.

Is Oobleck Environmentally Friendly?

Oobleck is made from simple, non-toxic materials and can be disposed of in the trash, making it a relatively environmentally friendly substance.

Can I Use Oobleck as a Substitute for Glue?

Oobleck is not a good substitute for glue, as it doesn’t hold materials together well. Stick to using it as a fun science experiment or sensory activity.

What Happens If I Freeze Oobleck?

Freezing oobleck can change its properties and make it more difficult to work with. It’s best to avoid freezing it unless you’re experimenting with different ways to play with the substance.

Can I Add Scent to My Oobleck?

Yes! You can add essential oils or other scents to your oobleck to create a sensory experience. Be careful not to use too much, as it may impact the consistency of the substance.


Now that you know how to make oobleck and have a better understanding of its properties, it’s time to try it out for yourself. It’s a great activity to do with kids or as a fun science experiment on your own. Just remember to be careful with the substance, as it can be messy and difficult to clean up. So, get creative and have fun with your oobleck!
