Scientist nowadays, research their thing, in Kitchen ! The latest news on science research brings us to making water run uphill.
Toss water on a hot pan and it sizzles and evaporates. Toss water on a really hot pan, and the water beads up and starts roaming around. Now, turn your hot pan into a hot small staircase and watch the water climb the stairs.
If a pan’s really hot, the water starts to evaporate before it even touches the surface. The evaporating water, in the airy form of a water-vapor cushion, holds the droplet above the pan. With moves as smooth as Fred Astaire, the droplet glides around on air.
“The drop rides along on the vapor like a boat on a river,” said physicist Heiner Linke from the University of Oregon. “The vapor is generated between the droplet and the ratchet’s surface in a narrow gap, about the width of a human hair. The vapor needs a way to get out of there, and it’s going to take the easiest way out. There’s always going to be one direction in which it’s easier to get out.”
