Oobleck is a non-Newtonian fluid, which means it does not follow the usual rules of fluid dynamics. It is made by mixing cornstarch and water in a specific ratio. When pressure is applied to oobleck, it behaves like a solid, but when the pressure is released, it flows like a liquid.
The behavior of oobleck can be explained by the concept of dilatancy. When pressure is applied to oobleck, the cornstarch particles are forced closer together, making it harder for the water to flow between them. This creates a solid-like behavior. When the pressure is released, the particles are able to move freely again, causing the oobleck to flow like a liquid.
Oobleck and other dilatant materials have been used in various industries, such as in body armor to protect against impact, in construction materials to improve stability, and in food processing to thicken certain products. They are also commonly used in science experiments and demonstrations to showcase non-Newtonian behavior.
Yes, the behavior of oobleck can be described using various equations and mathematical models. The most commonly used equation is the Herschel-Bulkley model, which relates the stress and strain of a non-Newtonian fluid. Other equations, such as the Bingham plastic model, can also be used to describe the behavior of oobleck.
Oobleck and dilatants can be used as a fun and interactive way to teach about non-Newtonian fluids and the concept of dilatancy. They can be used in various experiments and demonstrations to showcase their unique properties and how they can be described using equations and math. They can also be used to spark interest in science and math among students of all ages.
