Oobleck & Dilatants: Physics, Equations & Math for Sci-Math Exposition

  • Thread starter Oohbleck
  • Start date
In summary, Oobleck is a non-Newtonian fluid made from a mixture of cornstarch and water. It has properties of both a solid and a liquid and is named after the substance in a Dr. Seuss book. Dilatants, a type of non-Newtonian fluid, become thicker and more solid-like when under shear stress. They are used in various products such as quicksand and body armor, and in medical procedures. The behavior of Oobleck and dilatants can be described using mathematical models and concepts such as viscosity and shear stress.

Hi everyone,

May I ask about the physics and equations behind Oobleck and Dilatants in general. We shall be using this information for our Sci-Math Exposition (more math needed)?

Related to Oobleck & Dilatants: Physics, Equations & Math for Sci-Math Exposition

1. What is oobleck and how does it behave?

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.

2. What is the scientific explanation for oobleck's behavior?

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.

3. What are some real-life applications of oobleck and dilatants?

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.

4. Can oobleck be described using equations and math?

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.

5. How can oobleck and dilatants be used in a sci-math exposition?

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.
