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.

Best link all day. Thanks!

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.
