ICICLE
Ice that forms in the shape of a narrow cone hanging point down. It usually forms when liquid water from a sheltered or heated source comes in contact with below-freezing air and freezes more or less rapidly as it flows.

Thus an ice crystal or icicle sublimes under low relative humidity at temperatures below 0°C. The process is analogous to evaporation of a liquid. Colloquially the terms are used interchangeably for the solid-vapor transition (evaporation).
Low overnight temperatures in Canberra during July 1994, combined with a malfunctioning automatic sprinkler, produced this display of icicles on play equipment at a Canberra pre-school centre (courtesy of Gary Schafer, Canberra Times).
