Ice Formation (3 of 3)

Caption

Regular ice crystals (red) are mixed with “intermediate ice” (green) near the end of the process of crystallizing from supercooled water. University of Utah chemists used computers to determine that water, which doesn’t necessarily become solid at its 32 degrees Fahrenheit freezing point, actually can get as cold as minus 55 F before it must freeze.
