Stanford researchers solve the mystery of the dancing droplets

This beautifully-made video about a beautifully-colored series of experiments from a Stanford research team showcases how a observing a few droplets of food coloring -- made of water and propylene glycol -- have led t...

Hydrophobic metal made with laser-etched microscopic patterns

Scientists from the University of Rochester have created water-repelling metal by laser-etching nanostructures into the surface. Watch as water droplets bounce like water balloons off of the metal's super-hydrophobic ...

What makes that fresh rain smell? MIT films rain drops to find out

Why do we smell that fresh earthy scent before and/or after it rains? With high-speed cameras, MIT researchers have filmed rain drops, and believe that the footage explains petrichor, the "pleasant smell that frequent...

Every Last Drop: How to Save Water

From Nice and Serious and the scroll-worthy storytelling of Every Last Drop, this UK-made primer is excellent for reminding everyone to save water, especially those of us who live in drought-affected areas...

Leidenfrost Maze: Self-propelled droplets on a hot jagged surface

The Leidenfrost Maze, designed and built by Carmen Cheng and Matthew Guy at the University of Bath, demonstrates how Leidenfrost droplets can be self-propelled in a controlled way by the jagged...

Coalescence cascade: A water drop dances in slow motion

Coalescence cascade! Watch MIT’s high speed cameras capture drops of water hitting the surface of water at 10,000 frames a second — that’s 400 times faster than the human eye....

Coalescence cascade: The bouncing droplet in slow motion

What is a coalescence cascade? When droplets of water contact the surface of water, it doesn't actually get absorbed straight away like you may think it does. What happens is it gradually bounces up and down until ...
