Spectacular 2 drops of water combined in 15 milliseconds

Scientists have just captured the moment when two drops of liquid come together, providing a rare glimpse into the process that the human eye cannot observe.

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) can accurately see when a drop of water is exposed with another drop of water. This process creates a new texture within 15 milliseconds after they combine.

Thomas Sykes, lead author of the study, said the use of high-speed imaging provides new insights into how complex water droplets interact.

"In the past, you often wondered if two drops of water interacted with each other or if one drop would pass through another. The two cameras recorded the interaction to answer that question," Alfonso Castrejon- Pita, a professor at Oxford University (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 developed imaging techniques have opened a new window on droplet research technology , " Wilson added.
