Vortical interfaces between immiscible fluids - a slow-motion video of various vortexes of Newtonian and non-Newtonian fluids, set to Soundgarden's Black Hole Sun, with explanatory captions. Pleasing to the eyes.

I should point out that the linked page has some serious HTML deficiencies, but I can't hold that against physicists. Direct link to Quicktime video here.

OK, granted, I'm drunk, but that was fucking awesome. Also: um, what's the difference between Newtonian and non-Newtonian fluids?

Great performance by the oil treatment.

Non-newtonian fluids contain less apple juice. Also, shear stress in non-newtonian fluids isn't just a function of velocity difference.

Wikipedia gives the complete story, as always.

Newtonian fluids shear linearly - that is, the more you try to move something through them, the more the fuid resists. Non-Newtonian fluids are things like ketchup, mayo, and silly putty - under some force conditions, they flow, while in other conditions, they behave like (soft) solids.

It seems that thixotropic and rheopectic are actually useful words to know. I learned them at a previous job, but it's surprising how often they come up in conversation.

Informative and fun to watch. Thanks very much for this link.
