Water's properties at supercooled temp measured for 1st time
US researchers have measured the properties of supercooled liquid water for the first time, using a laser-based cooling technique. They found the time taken for supercooled water to crystallise into ice drops reduced from nanoseconds at -11ºC to hours at -147ºC. The study ruled out the possibility of a singularity temperature where supercooled liquid water snaps instantaneously into solid ice.
