Not all microfluidic devices use tiny channels to pump and mix fluids. Some, like the Vortex Fluidic Device (VFD), conduct their microfluidic mixing in thin films of fluid. The VFD Keep reading

“Columbia”
“Columbia” is a music video illustrated with fluid dynamics, chemistry, and biology by the Beauty of Science team. It’s got everything from precipitation to crystallization, from infrared imagery of wakes Keep reading
A Macro View of Weathering
Water constantly weathers sedimentary rock, both physically — through abrasion — and chemically — through dissolution and recrystallization. Now researchers have gotten their first view of this weathering at the Keep reading
Acidic Sea Spray
As waves crash and break, they generate a spray of droplets — known as aerosols — that make their way into the atmosphere. Researchers investigated the chemistry of these aerosol Keep reading
“Catalysis”
Catalysts speed up chemical reactions without being consumed themselves. In “Catalysis” the Beauty of Science team shows 5 different examples of catalytic reactions, from acetone oxidation to yeast fermentation. The Keep reading
Precipitation
Chemistry and fluid dynamics often go hand-in-hand. Here chemical reactions produce visible precipitates as one chemical drops into the other. The shapes that form are distinctly fluid dynamical, with vortex Keep reading
Hot Ice, Buoyancy Tricks, and More DIY Fun
Here’s a smorgasbord of DIY experiments from Dianna at Physics Girl. Some are fluidsy, some aren’t, but all of them give you a chance to stretch your science muscles at Keep reading
Fluorescent Dancing Droplets
These fluorescent droplets of glowstick liquid jiggle and dance in a solution of sodium hydroxide. Some droplets jitter. Some rotate. And some undergo one coalescence after another. It’s always fun Keep reading
Molten Thermite
This glowing, molten liquid captured by the Slow Mo Guys is thermite. The chemical reaction behind thermite is highly exothermic, hence its intense glow. There’s some great fluid dynamics hiding Keep reading
“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 Keep reading
