How to make oobleck

Have you ever found yourself in the middle of a rainy afternoon with nothing to do, or perhaps you’re a curious parent looking for a fun and educational activity to engage your children? The search for a simple yet fascinating project can sometimes lead you to the intriguing world of non-Newtonian fluids. Among the most popular examples of these is oobleck, a slime-like substance that behaves in captivating ways. So, how do you create this magical mixture?

To make oobleck, mix 2 parts cornstarch with 1 part water in a bowl until you achieve a consistency that feels solid when you apply pressure but flows like a liquid when you let it sit.

Creating oobleck is a delightful project that requires minimal ingredients and offers maximum entertainment and learning opportunities. Start by measuring out 2 cups of cornstarch and placing it in a mixing bowl. Next, measure 1 cup of water and gradually pour it into the cornstarch, stirring continuously. You may not need all the water, so add it slowly until you reach the desired consistency–aim for a texture that feels solid when squeezed and flows easily when released. If it’s too runny, simply add more cornstarch; if it’s too dry, add a splash more water. Once mixed, you can experiment with your oobleck: try punching it, letting it drip, or using it in creative play. Cleaning up is straightforward too, as oobleck can be swept up easily once it dries!
