New research by NIST and Georgetown scientists deciphers the mechanisms that cause the materials to switch between liquid and solid in response to stress. Oobleck's name is borrowed from a Dr. Seuss ...

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, ...

For the first time, researchers have been able capture images providing unprecedented details of how particles behave in a liquid suspension when the phenomenon known as shear thickening takes place.

What do paint, dishwasher detergent, ketchup and blood have in common? All are composed of particles suspended in a carrier liquid and flow when stirred or forced, but remain thick or even gel-like at ...

ITHACA, N.Y. – In things thick and thin: Cornell physicists explain how fluids – such as paint or paste - behave by observing how micron-sized suspended particles dance in real time. Using high-speed ...
