Soft rime ice is just ice crystals that formed as supercool water froze when it hit a surface. These crystals are white or “milky,” not clear. They only form in the absence of wind.

Rime is already helping power close to 100 million phone calls a month, said Clifford. “If you call Domino’s or Wingstop, there’s an 80 to 90% chance that you hear a Rime voice,” she said.
