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, ...

We continue our exploration of fluids and fluid dynamics. We continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places ...

From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the ...

The first ever camera footage from inside a centrifuge has revealed a new mystery in the physics of fluids. A centrifuge is a standard piece of laboratory equipment that spins fluid samples at high ...

Scientists used fluid dynamics to learn how to get the most flavor from pour-over coffee. By Katrina Miller More than a billion cups of coffee are consumed daily: French-press, espresso, cold brew, ...
