Oobleck and Non-Newtonian Fluids

Dr. Boyd introduces non-Newtonian fluids by making Oobleck, a shear thickening fluid. The video explains viscosity, shear thickening, and shear thinning, using examples like ketchup. The hands-on activity involves mixing cornstarch and water to create Oobleck, demonstrating its unique properties when stress is applied. The video emphasizes understanding fluid behavior in a simple, engaging manner.

What materials are needed to make Oobleck?

Explain the concept of viscosity in your own words.

What are the two categories of non-Newtonian fluids mentioned?

Describe the behavior of a sheer thickening fluid when stress is applied.

How does ketchup serve as an example of a sheer thinning fluid?

What happens to Oobleck when you apply stress to it?

In what way does Oobleck behave differently when at rest compared to when stress is applied?
