What is the mixture called when water and cornflour mix?

When water and cornflour are mixed together, the resulting mixture is often referred to as "oobleck." Oobleck is a non-Newtonian fluid, meaning it exhibits properties of both liquids and solids depending on the applied stress. When pressure is applied, it becomes more solid, but when at rest, it flows like a liquid. This unique behavior makes oobleck a popular substance for educational demonstrations and playful experimentation.
