“Oil Spill”
In “Oil Spill” artist Fabian Oefner explores the shapes and colors of oil floating atop water. An old adage tells us that oil and water don’t mix, but this is not Keep reading
Colors in Macro
Milk, acrylic paints, soap, and oil – all relatively common fluids, but together they form beautiful mixtures worth leaning in to enjoy. Variations in surface tension between the liquids cause Keep reading
“Memories of Paintings”
In “Memories of Paintings,” Thomas Blanchard gives us an up-close view of fluids and mixing. It’s a calming and curious video made from combinations of paint, oil, oat milk, and Keep reading
Daily Fluids, Part 3
A lot of the fluid dynamics in our daily lives centers around the preparation and consumption of food. (And in its digestion afterward, but that’s another story!) Here are a Keep reading
Emulsion Impact
Emulsions – mixtures of two immiscible fluids – are quite common; the oil and vinegar combination used in many salad dressings is one. The image sequence above shows the first Keep reading
Selective Suction
A thin spout of water is drawn up through a layer of oil in the photo on the right. This simple version of the selective withdrawal experiment is illustrated in Keep reading
“Pacific Light”
This lovely video from Ruslan Khasanov showcases the beautiful interplay of surface tension, diffusion, and immiscibility in common fluids. With soy sauce, oil, ink, soap, and a little gasoline, he Keep reading
Bubbles, Drops, and Colors
The immiscibility of oil and water creates a multitude of bubbles of all sizes. A lack of miscibility occurs when the forces between like molecules are very strong for two Keep reading
Droplets Within Droplets
This video shows a multi-layered droplet, in which several droplets are formed one inside the other as an initial drop falls through a layer of oil sitting atop another liquid. Keep reading
