Oobleck Lab activity

Author: Jason Fritz
Description:

Viscosity is a fluid’s resistance to flow . Water flows easily; it has low viscosity . Syrup and molasses resist flowing; they have high viscosity . Most fluids follow Newton’s Law of Viscosity, which says that the harder or faster a fluid is pushed, the faster it flows—but some do not . They are known as non-Newtonian fluids . Investigate a non-Newtonian fluid—a mixture of cornstarch and water, often called oobleck— that exhibits some strange properties. Materials like oobleck that respond to forces in unique ways are called smart materials

Oobleck and Non-Newtonian Fluids: Crash Course Kids #46.1

Ever heard of Oobleck? How about Non-Newtonian fluids? Well, today Sabrina is going to show us that things can sometimes behave like a solid, and sometimes like a liquid depending on how much force is applied to them. In this episode of Crash Course Kids, we'll talk about some weird stuff that's still... normal.

Running of the Oobleck

They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid.

Normal Stuff in Not-So-Normal Places: Crash Course Kids 46.2

So, what happens to normal stuff (like water) when it goes to not so normal places? What happens if you take a glass of water to the top of Mt. Everest? Or Space? In this episode of Crash Course Kids, Sabrina shows us how matter is affected by different pressures and how that make water do some weird things.
