High-viscosity fluids, on the other hand, behave quite differently. They flow slowly, resist deformation, and, in some cases, act more like solids than liquids, posing challenges when it comes to ...

In this video we take a look at viscosity, a key property in fluid mechanics that describes how easily a fluid will flow. But there's more too it than that! We'll start by defining viscosity using ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

If you mix cornstarch and water in the right proportions, you get “oobleck”: something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but ...
