When the world's expert on pygmy mammoths asks you a question about ketchup, you have to find the answer. The context was the article I wrote last week about non-Newtonian fluids, where researchers at ...

One of these is not like the others: honey, water, ketchup, and blood. The answer? Water, because the other three are all non-Newtonian fluid. When Isaac Newton first defined the properties of an ...

Ketchup, which is made by heating ripe tomatoes, filtering them, boiling them at a low temperature, and then adding sugar, salt, vinegar, etc., is a seasoning that goes well with hot dogs, sausages, ...

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 ...

You may be familiar with a common science demonstration done in classrooms: If you mix cornstarch and water together in the right proportions, you create a gooey material that seems to defy the rules ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
