In experiments at SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory's Advanced Light Source, scientists observed a surprisingly dense form of water that remained liquid well beyond its typical freezing point. Researchers applied a superthin coating of water—no deeper than a few molecules—to the surface of a barium fluoride crystal. This surface was expected to stimulate ice formation, but even when chilled to a temperature of about 6.5 F—well below water’s normal freezing point—the water remained liquid. The research, published in Nature Scientific Reports, spanned more than three years and represents a milestone in understanding some of the many exotic properties water exhibits under a range of conditions.
