Yes, mixing cornstarch with water creates a unique mixture known as a non-Newtonian fluid, often called oobleck. To make it, combine 1 part cornstarch with 1.5 to 2 parts water in a bowl and stir until the consistency is even. It will act like a solid under pressure but flow like a liquid when at rest. This is a fun and educational experiment that showcases interesting properties of materials. Enjoy exploring the science behind it!
FAQs & Answers
- What happens when you mix cornstarch with water? Mixing cornstarch with water creates oobleck, a non-Newtonian fluid that behaves like a solid under pressure and flows like a liquid when not pressured.
- What is the correct ratio of cornstarch to water to make oobleck? The recommended ratio is 1 part cornstarch to 1.5 to 2 parts water, stirred together until a smooth consistency is achieved.
- Why does oobleck behave like both a solid and a liquid? Oobleck is a non-Newtonian fluid, meaning its viscosity changes under stress; it acts solid when pressure is applied and flows like a liquid when at rest.
- Is oobleck safe to play with? Yes, oobleck is non-toxic and safe for educational play, but it should be disposed of properly to avoid clogging drains.
