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 ...

This article was originally published with the title “ Ketchup Is Not Just a Condiment: It Is Also a Non-Newtonian Fluid ” in SA Space & Physics Vol. 4 No. 3 (June 2021) doi:10.1038 ...

It puts up some resistance to flow. And that is this viscosity. But a non-Newtonian fluid now can adapt its viscosity. Smartly, it can flow more easily– for example, when we push it. Or it can ...

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 ...

Ketchup is designed to be a non-Newtonian fluid, so when you put it on a hot dog, it melts into your hands and clothes and does not run off, but only when you put it in your mouth.

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 ...

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.

It’s a fine example of a so-called “non-Newtonian fluid.” Isaac Newton described the properties of an “ideal liquid” back in the 17th century, one of which is viscosity, loosely defined ...
