Watch Water Flow Uphill in This Fun Science Experiment [VIDEO]
Have you ever used water to test whether a frying pan is hot enough? If you have, then you’ve probably witnessed the Leidenfrost Effect, a phenomenon in which a liquid dropped onto a mass significantly hotter than its boiling point will float or skitter across the surface rather than evaporate. Now physicists at the University of Bath are taking this common kitchen practice to a whole new level.
Playing off this principle, researchers discovered that the Leidenfrost Effect can not only cause liquids to evaporate much more slowly, but it can also allow liquids to flow uphill or in defined directions. Because it uses no moving parts, the process could be used to cool an overheated microchip inside of a computer. But even without a known practical application, getting water flow to uphill without any mechanical assistance is still pretty cool.
