“Waves”
The “Waves” installation by artist Daniel Palacios appears deceptively simple, just a rope mounted between two motors. But once the motors start spinning, it is anything but. The installation shifts in response to those around it, creating varying numbers of steady, standing waves or even wildly chaotic ones that whistle through the air. It’s a neat visualization of one of the most commonly-measured quantities in physics: the changes in a wave with time. (Video and image credit: D. Palacios; via Flow Vis)

Audubon Photography Awards
Several of this year’s Audubon-Photography-Award-winning photos feature birds interacting with fluids. The Grand Prize Winner, by Joanna Lentini, features a diving double-crested cormorant. Like many other species, these cormorants launch themselves into shallow waters from above and endure some incredible forces to do so. They’re no slackers underwater, either; when I encountered a flightless cormorant while snorkeling in the Galapagos, it outswam me in an instant.
The other prize winners above are a little more splashy. The American dipper’s splash curtain comes from sticking its head underwater in search of prey. The Anna’s hummingbird seen in the last image is playing in the spray of a fountain and showing off its aerial agility while doing so! (Image credits: cormorant – J. Lentini, dipper – M.

“Oooh !! My Delicious Coffee”
I’m not a coffee person, but Thomas Blanchard’s “Oooh !! My Delicious Coffee” manages to capture my favorite part of the beverage – watching cream and coffee mix. From feathery flows driven by surface tension to droplets floating like miniature cappuccinos, the short film features many of the fantastical landscapes we find when staring into a coffee cup. But don’t get too eager to drink it; Blanchard used a combination of coffee, oil, and paint to achieve those effects! (Image and video credit: T. Blanchard)

Alien Eggs? A Virus?
Nope, they’re hydrogel beads! The team at Chemical Bouillon seem to have once again coated them in something like paint before placing them in water. As the gel beads absorb water, they expand, tearing through their coating. The result is weirdly mesmerizing and kind of creepy. It’s no wonder that special effects artists have historically turned to fluids for sci-fi films! (Image and video credit: Chemical bouillon)

Making Waves
The Seoul Aquarium is now home to an enormous crashing wave, courtesy of design company d’strict. Check out several different views of the anamorphic illusion in their video above. There’s no word on the techniques used to generate the animation, but it’s certainly a cool visual! (Image and video credit: d’strict; via Colossal)

Mammatus Clouds
Mammatus clouds are a relatively rare and dramatic variety. One advantage of living in Colorado is that I see them somewhat often, especially during our stormy springs and summers. This video by Mike Olbinski features a dramatic skyscape of mammatus clouds (here in Colorado, natch) at sunset.
Although they’re often associated with stormy weather, there’s no widely accepted theory as to how mammatus clouds form. Their lobe-like protrusions form from cold, sinking air, but this is about as far as theories agree. It’s even unclear what their relation to extreme weather may be since these short-lived cloud formations can appear around, before, or even after such weather. (Image and video credit: M. Olbinski)

“As Above”
In Roman Hill’s “As Above,” we see expansive celestial landscapes: nebulae, the corona of a star, and expanding interstellar dust clouds. Except, in reality, we are watching fluids undergoing a chemical reaction, on a canvas only 8 square millimeters in size. It’s a fun — and beautiful — reminder that the patterns of physics repeat across many scales. (Video and image credit: R. Hill)

Marangoni Bursting
Placing a mixture of alcohol and water atop a pool of oil creates a stunning effect that pulls droplets apart. The action is driven by the Marangoni effect, where variations in surface tension (caused in this case by the relative evaporation rates of alcohol and water) create flow. David Naylor captures some great stills of the flow, including the only example of a double burst I’ve seen so far. For more on the science behind the effect, check out this previous post or the original research paper. (Image credit: D. Naylor; see also this previous post)

Seeping Sculptures
Drips, blobs, and squishes – that’s how artist Dan Lam describes her recent series of sculptures. The pieces are a mix of polyurethane foam, resin, and acrylic, decorated in bold gradients of neon color. I love the fluidity of each piece, as well as the decorative piping of spikes on many of them. (As a matter of fact, they remind me of this work.) Check out more of Lam’s work on her website and Instagram feed. (Image credit: D. Lam; via Colossal)

“Focus, Vol. 2”
This short film from photographer Roman De Giuli focuses on ethereal and abstract fluids. What you’re watching is primarily paint, with a little in the way of flow additives. There’s lovely marbling and some impressively sharp edges, but mostly you can just sit back and enjoy the flow! (Image and video credit: R. De Giuli)
