Scientists have captured the moment two drops of liquid come together, providing a rare glimpse into a process that can’t be seen by the human eye.
By placing two high-speed cameras that can record images at up to 25,000 frames per second, researchers from the University of Leeds (UK) observed exactly when a drop of water came into contact. with another drop of water. This process creates a new texture within 15 milliseconds of them combining.

The use of high-speed imaging provides new insights into how water droplets interact complexly, said Thomas Sykes, lead author of the study.
“In the past, you used to wonder if two drops of water when they interacted with each other or if one would pass through the other. Two cameras recorded the interaction to answer that question,” Alfonso Castrejon- Pita, professor at the University of Oxford (UK), co-author of the study said.
Researchers are still learning more about how to change the “behavior” of water droplets by analyzing their internal flow .
“The imaging techniques developed have opened a new window on waterdrop research technology ,” added Mr. Wilson.
