But get them together and they form a non-Newtonian fluid. To really understand these materials, ... it works the opposite of the previous examples: The liquid becomes more viscous, not less.

Non-Newtonian fluids may exhibit shear thinning, where the viscosity decreases with stress; common examples include ketchups and sauces that can appear almost solid-like at rest.

Oobleck has long been my favorite example of a non-Newtonian fluid, and I'm not alone.It's a hugely popular "kitchen science" experiment because it's simple and easy to make. Mix one part water to ...

This type of non-Newtonian fluid is called "shear thickening" – it becomes thicker (more viscous) when force is applied. Other examples include quicksand and some types of body armor made with similar ...

We may finally understand why non-Newtonian fluids act so strange. / Hard Science / NIST / Non Newtonian Fluids / Oobleck Updated 5.13.16, 9:49 AM EDT by Jelor Gallego ...

Experts refer to these materials as “non-Newtonian fluids,” of which ketchup and blood are prime examples. ... The results demonstrate that blood plasma is itself a non-Newtonian fluid.

Elastoviscoplastic (EVP) fluids like mud, concrete, and lava are a type of non-Newtonian fluid that exhibit both solid and fluid-like behavior depending on the forces they are subjected to (i.e ...

The most famous non-Newtonian fluid is probably Oobleck, a mixture of cornstarch and water. In this experiment, you will compare it to a lesser-known non-Newtonian fluid: ketchup. Tomato ketchup is a ...

Many non-Newtonian fluids exist that are staples of YouTube videos and science magic shows. But they're also familiar from the kitchen: pudding is probably my favorite one (mmm, pudding), but ...
