Supercooling liquid water to temperatures lower than ever achieved before has revealed new evidence that water can exist as two different liquids simultaneously.
Supercooled water – liquid water cooled below its freezing point without being allowed to freeze – has been baffling chemists for decades. Previous studies found that the extent to which water molecules pack together, known as their density, starts to fluctuate more and more as water is cooled to extremely low temperatures.
Since then, evidence has been mounting that these fluctuations may indicate the presence of two …
