On January 15, 1919, in Boston's North End, a 50-foot-tall tank holding 2.3 million gallons of molasses burst, unleashing a deadly wave that rose nearly 25 feet high at one point. The disaster killed 21 people and injured another 150. Nearly one hundred years later, an analysis carried out by a group of Harvard fluid dynamics physicists explains how "cold temperatures and unusual currents conspired to turn slow sticky goop into a deadly speeding wave."

These charts clearly show how some Olympic swimmers may have gotten an unfair advantage. A data heavy analysis of the swimming in Rio that shows that some lanes were faster than others. On the Washington Post Wonk Blog.
For an old North Sea hand, 40-foot waves, the kind that would terrify most of us, were nothing out of the ordinary. But the emergence from nowhere of a single wave that was more than twice as high as the others was exceptional. Warwick had encountered a rogue wave. When Good Waves Go Rogue
The Wet-Dog Shake (SLYT). Scientists have worked out the optimum amount of shaking that animals have to do to dry themselves after getting wet. Filming in slow motion, they captured various animals shaking themselves off, from a wet mouse to a big grizzly bear. [more inside]
Fuck Yeah Fluid Dynamics celebrates fluid dynamics in all their fuck-yeahness.
Two galleries of fluid motion - one from the journal Physics of Fluids, and one from MIT. The MIT gallery shows some common everyday fluids in unexpected lights. The PoF gallery (which is quite extensive, check out the 85-09 archives) mostly concerns itself with more esoteric interests. Some of the results presented have a stark beauty and some are riotously colourful. I personally love the results that look at turbulence and transition. Also, some visualisations from the past ten or so years are presented as video! (PDFs, Quicktime)

The Great Molasses Flood of 1919 in which 21 people died. (A picture of the devastation.) Another account from The Smithsonian. A present day picture of the site (scroll to the bottom). Brief accounts of two other molasses floods. And while we're at it, don't forget the London Beer Flood. Cheers.
Gallery of Fluid Dynamics. 'One of the most attractive features of fluid mechanics is the beauty of the flows one encounters. Whether one is observing vortex streets, the potential flow around an airfoil or body, shock refraction or diffraction, or waves breaking on a beach the aesthetic appeal of fluid mechanics is impossible to deny.
