These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick
It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power
