Ephemeral clouds drift through unusual places in artist Berndnaut Smilde‘s works. He creates his clouds from smoke and water, launching them for a matter of seconds before they dissipate. During that time, he and his collaborators take photographs of the clouds, creating a memento of a time already past. Catch more of Smilde’s short-lived weather on his website and Instagram.

Handmade kinetic sculptures by artists Marion Pinaffo and Raphaël Pluvinage spin and paint the sky in colorful smoke in “Sfumato”. Named for an artistic technique in which shading gradually changes tone and hue, the installation was built, the artists note, “without motors, electronics, computer generated images, or artificial intelligence”. Just pure hands-on engineering and physics. Watch the short video of the installation in action for the full effect. You can find more of their work on their website, Vimeo, and Instagram.

Billowing turbulence, mushroom-like Rayleigh-Taylor instabilities, and spreading flows abound in Vadim Sherbakov’s “Origin.” The short film takes a macro looks at fluids — inks, alcohols, soaps, and other household liquids. It was filmed entirely on a DJI Pocket 2, a rather small, stabilized pocket camera. It’s a testament to what you can achieve with some experimentation and relatively inexpensive equipment.

Artist Roman Hill made this official music video to go with Thomas Vanz’s “Lucid.” The imagery, formed from ink and other fluids, warps our sense of scale. Though the camera focuses on an extremely small area, to our eyes the results shift from nebulas to oceans and back again. There are likely a whole host of phenomena going on here, but without knowing more about Hill’s ingredients, I can only speculate that there are Marangoni flows driven by variations in surface tension and maybe some density instabilities going on between fluid layers. I’m also fairly confident that Hill has played with time reversal in the video editing. Regardless of the secrets in its making, the film is captivating and gorgeous. (Image and video credit: R.

When Tomasz Wilk settled to camp one evening on the banks of a Polish river, he didn’t expect to find fountains in the shallows. Though reminiscent of an archer fish’s shot, this stream comes from a freshwater mussel. In spring, the mature female thick-shelled river mussels head to the shallows, where they edge a bit of their shell out of the water and release this fountain of water and larvae. Once dispersed, the larvae will attach (harmlessly) to the gills of fish until they grow into a juvenile mussel. (Image credit: T Wilk; via Wildlife POTY)
This year’s Traveling Gallery of Fluid Motion will be hosted in Salt Lake City. There’s currently an open call to scientists and artists for submissions inspired by Leonardo Da Vinci. From the organizer:
This particular exhibition aims to showcase the historical interplay between art and science, with Da Vinci serving as a guiding luminary whose multifaceted genius continues to inspire innovation and creativity.
Artists and scientists from diverse backgrounds and disciplines are invited to submit their works, whether new creations or existing pieces, that delve into the fascinating themes of fluid dynamics, aerodynamics, and flight. The exhibition will take place at The Leonardo Museum in Salt Lake City, Utah, during the Fall/Winter season of 2024.
We welcome submissions in any medium, size, or stage of production, including, but not limited to video, photography, painting, 3D printed models, sculpture, installation, mixed media, and beyond. Although not a requirement, artists and scientists are encouraged to explore the intersections between art and science by drawing inspiration from Da Vinci’s legacy while infusing their unique perspectives and interpretations.
Submission Deadline: April 1, 2024

It’s all blue skies in Roman De Giuli’s short film, “Perfect Sky.” Created with paint, ink, and glitter on paper, it’s a relaxing piece of fluid art. Put on your headphones, take a deep breath, and plunge in. You’ll see lots of gorgeous Marangoni effects, some low Reynolds number mixing, and various instabilities. (Video and image credit: R.

Yellowstone National Park is always fascinating and surreal, but especially so in winter when volcanically-heated geysers and springs meet frigid, snowy weather. This short film from Drew Simms shows the park and its wildlife in the depths of winter. The bison rely on thick, shaggy fur coats to trap heat and keep dry. Steam and mist mingle around springs and giant plumes rise from geysers. What a strange and beautiful landscape! (Video and image credit: D. Simms)
In the 1930s, Harold Edgerton used strobed lighting to capture moments too fast for the human eye, including his famous “Milk-Drop Coronet”. Recreating his set-up is far easier today, thanks to technologies like Arduino boards that make timing the drop-strobe-camera sequence simple. This poster is a collage of Edgerton-like images captured by students at Brown University. Even nearly a century after Edgerton, there are countless variations on this beautiful slice of physics: all from the splash of a simple drop striking a pool. (Image credit: R. Zenit et al.)
These firework-like patterns spread when dyes are added atop a viscous but miscible lower fluid layer. Here, researchers use lower layers like corn syrup and xanthan gum; then they spread dye mixtures including ammonia and vinegar atop those layers. Because the upper and lower layers of fluid are miscible and can diffuse into one another, they together form elaborate patterns. The mixing of the two layers creates gradients in surface tension that can drive the flow and create these mocha diffusion patterns. (Image credit: T. Watson and J. Burton)
