Water can flow below -130 C

Water can flow below -130 C: Water is extremely difficult to chill in a way that makes it sluggishly flowing. Ove Andersson has accomplished this feat by exposing crystalline ice, in which the atoms are arranged in an orderly manner, to increased pressure at temperatures below -130o C. The order of the molecules and the ice collapsed into amorphous ice, with random order among the water molecules.
“When I then raised the temperature, the ice transformed into sluggishly flowing water. This water is like regular water but its density is 35 percent higher, and the water molecules move relatively slowly, that is, the viscosity is high.”
