Scientists supercool water to -42.5ÂºC without freezing it
Europe-based researchers have discovered that liquid water can be cooled down to -42.55ÂºC, far below its normal freezing point of 0ÂºC. The team cooled tiny droplets in vacuum and used lasers to measure the diameter change to calculate their temperature. Another team showed, water on supercooling can exist in two interchangeable liquid states with different densities, and called it 'singularity'.
