Are you searching for a fun and educational activity to engage your little ones? Look no further than the magical world of oobleck! This intriguing substance, known for its unique properties of behaving like both a liquid and a solid, is not only entertaining but also offers a wealth of learning opportunities for children of all ages. In this blog post, we’ll guide you through the simple steps to create oobleck right in your own kitchen, providing hours of sensory-rich play and scientific exploration for your curious kids. Get ready to dive into a world of hands-on fun with oobleck!
What is Oobleck?
Today, I’m going to show you this fun and easy craft idea your kids will love! DIY Homemade Oobleck! It is a non-Newtonian fluid… so you can ask yourself the question… is it a solid? or a liquid?
Oobleck is a fascinating non-Newtonian fluid that defies traditional definitions of matter. Named after the gooey substance featured in Dr. Seuss’s book “Bartholomew and the Oobleck,” it’s made from a simple mixture of cornstarch and water. What makes oobleck truly unique is its behavior—it behaves like a liquid when poured slowly, but it can also exhibit solid-like properties when subjected to sudden force or pressure.
At first glance, oobleck may seem like just another gooey substance, but its unusual properties make it a captivating material for science experiments, sensory play, and hands-on learning activities. When mixed to the right consistency, oobleck forms a thick, viscous liquid that can be poured and molded like slime. However, when you apply pressure to it—by squeezing it in your hand or punching it—it temporarily solidifies, allowing you to form shapes or even walk on its surface.
The secret behind oobleck’s behavior lies in its unique molecular structure. Unlike most liquids, which have consistent viscosity regardless of force applied, oobleck’s mixture of water and cornstarch creates a suspension of starch particles in water. When force is applied, the starch particles become packed together, increasing the viscosity and giving oobleck its solid-like properties. However, when the force is removed, the starch particles relax, and oobleck reverts to its liquid state.
Oobleck’s ability to transition between liquid and solid states is not only fascinating but also offers valuable insights into scientific concepts such as states of matter, viscosity, and shear-thinning behavior. It’s a versatile material that can be used to explore a wide range of scientific principles in a hands-on and engaging way.
In addition to its educational value, oobleck is also incredibly fun to play with. Children and adults alike are mesmerized by its unpredictable behavior and tactile sensations. Whether you’re conducting science experiments, creating sensory bins, or simply enjoying some messy playtime, oobleck never fails to captivate and entertain.
In the next section, we’ll delve into how you can make your own oobleck at home with just a few simple ingredients. Get ready to unleash your inner scientist and have a blast with this magical substance!
Bartholomew and the Oobleck Activity
If you have a child under the age of 15, you likely have seen a video or had your kids ask to you make Oobleck. It’s typically right up there with making slime or custom Pom-Pom rugs, and while it’s fun to make, it has an even better origin story!
If you find yourself thinking, “Oobleck” is a really silly name, sounds like someone just made it up because it sounds funny… And you’d be right! It’s just that the person who made it up is none other than Dr. Seuss!
If you are like me, I LOVED Dr. Suess growing up, but somehow I missed the particular story of “Bartholomew and the Oobleck”. This very cute story follows a King who wants to control the weather, and the page boy who must save the kingdom from the king’s terrible ideas!
So to start, you might want to pick up the book or borrow it from the Library, read it together and then you can make the Oobleck for yourselves! Also, if you prefer there are a couple of very good readings of the book on Youtube.
In the story, Oobleck is this crazy liquid from the sky that doesn’t act like a normal liquid. It’s sticky yes, but it also can flow easily, or it can become hard as stone!
From a scientific standpoint, Oobleck behaves like a Non-Newtonian fluid. For the non-science nerds, it just means that Oobleck behaves differently in different situations.
After making your Oobleck, try and discuss with your kiddos what makes this material different than other fluids like water or glue. Oobleck is truly unique!

Fun Activities with Oobleck
Oobleck isn’t just any ordinary substance; its unique properties make it perfect for a wide range of entertaining and educational activities. Here are some creative ideas to spark your imagination and make the most of your homemade oobleck:
- Sensory Exploration:
Set up a sensory bin filled with oobleck and various tools for exploration, such as spoons, cups, and small toys. Let children dive their hands into the oobleck, squish it between their fingers, and explore its fascinating texture. Adding food coloring to the oobleck can enhance the sensory experience and make it even more visually appealing. - Oobleck Races:
Divide oobleck into individual portions and place them on a table or flat surface. Challenge participants to use only their fingers to move the oobleck from one end of the table to the other as quickly as possible. The non-Newtonian properties of oobleck will make this task both fun and challenging, as the substance behaves differently depending on the force applied. - Oobleck Art:
Use oobleck as a unique medium for artistic expression. Pour oobleck into shallow containers and encourage children to create designs, patterns, or even sculptures using their fingers or small tools. They can experiment with mixing colors, blending textures, and making imprints to create one-of-a-kind masterpieces. - Science Experiments:
Explore the scientific principles behind oobleck through fun experiments. For example, test the impact of force on oobleck by rolling it into a ball and bouncing it on a hard surface. Or, try pouring oobleck through a funnel to demonstrate its liquid-like behavior, then watch as it solidifies upon impact with the bottom of the container. - Oobleck Obstacle Course:
Create an obstacle course using trays or containers filled with oobleck. Participants must navigate their way through the course without touching the oobleck, using only designated pathways or stepping stones. This activity promotes problem-solving skills, spatial awareness, and gross motor development. - Educational Investigations:
Use oobleck to explore concepts such as states of matter, viscosity, and surface tension. Conduct experiments to compare the behavior of oobleck with other substances, such as water or traditional dough. Encourage children to ask questions, make predictions, and draw conclusions based on their observations.
Incorporating oobleck into learning and playtime offers numerous benefits for children. Not only does it provide a sensory-rich experience that engages multiple senses, but it also promotes creativity, experimentation, and scientific inquiry. By encouraging children to explore and interact with oobleck in various ways, you can foster their curiosity, critical thinking skills, and love for learning in a fun and hands-on way.
How to Make Oobleck with Cornstarch
Oobleck Ingredients:
- 1 Cup of Water
- 2 Cups of Cornstarch
- Food Coloring (optional but the colors are fun!)
- Mixing Bowl
Oobleck Directions:
- Pour one cup of cornstarch into the mixing bowl, and dip your hands into it. How does it feel in your hands? It’s really smooth and fine, since it’s made of really tiny particles.
- Now pour the water in, mixing slowly as you go. Keep adding more water until the mixture becomes thick (and hardens when you tap your fingers on it).
- Add the rest of the cornstarch into the mixture and continue to add water until you have a full bowl of the desired consistency. If it’s a little too runny, add more cornstarch, and if too dry, add a bit more water.
- Add the food coloring toward the end of the mixing process and mix until the color is as you wish. We tend to add it when the mixture is still runny and before adding the rest of the cornstarch.
Happy Crafting and Learning!
