This article provides a comprehensive oobleck recipe, perfect for kids and adults alike. Learn how to make this fascinating non-Newtonian fluid.
What Is Oobleck and Why Is It So Cool?
Oobleck is a non-Newtonian fluid, meaning it doesn’t behave like a typical liquid or solid. It’s a mixture of cornstarch and water, and it has fascinating properties. For example, it can feel solid when you apply pressure, but then it flows like a liquid when left undisturbed. This makes oobleck a great educational tool and a fun sensory activity for kids. Consequently, it’s very popular for science demonstrations and playtime. We’ll explore the science behind this unique substance and provide a straightforward oobleck recipe.
Understanding Non-Newtonian Fluids
Generally, Newtonian fluids, such as water, have a constant viscosity. However, with non-Newtonian fluids like oobleck, viscosity changes with applied force. Therefore, when you apply pressure to oobleck, it thickens and behaves more like a solid. Similarly, when the pressure is removed, it flows like a liquid. This interesting property is known as shear thickening. In addition, it makes oobleck an engaging material to investigate.
The Basic Oobleck Recipe You Need
Creating oobleck is very simple and only requires two common items: cornstarch and water. The oobleck recipe is very forgiving. Therefore, slight adjustments can easily be made to get the right consistency. However, using the correct ratio is very important for best results. Let’s delve into what’s needed.

The Science Behind The Oobleck Recipe
The intriguing properties of oobleck stem from its non-Newtonian fluid behavior. However, it is important to know the specific scientific concept at play. Understanding the science can enhance your appreciation for this substance.
Shear Thickening Explained
The shear-thickening nature of oobleck is due to the unique structure of the cornstarch particles. Consequently, when you apply pressure, these particles lock together. This action increases the viscosity, causing the material to temporarily act like a solid. Indeed, this process occurs because pressure increases the friction between cornstarch particles. Moreover, when the pressure is released, the particles can move freely again. Therefore, the material reverts to a more liquid-like state.
Why Does Oobleck Seem to “Melt”
When you stop applying pressure to the oobleck, it seems to “melt” because the particles aren’t being forced together. Subsequently, they regain the ability to slide past each other more easily. As a result, the fluid appears to liquefy. Further, this transformation showcases the reversible nature of the material’s viscosity change.
