  • Interesting fact: Precipitation causes K2 to be taller than Mount Everest for several weeks out of each year.
    • n precipitator One who precipitates; especially, one who urges on with undue haste; one who rashly brings to pass.
    • n precipitator That which brings about the precipitation or downfall of atmospheric moisture.
    • n precipitator That which causes or favors chemical precipitation; an apparatus for inducing precipitation. Specifically, a tank in which carbonates held in solution by free carbonic acid in water are precipitated by caustic lime, which neutralizes the free carbonic acid and permits the carbonates to fall to the bottom. This method of purifying water is used by dyers, and also in fitting hard water for use in steam-boilers.

His new found orchid. . . .

on my being's floor, a precipitate
from that immensely overfilled solution.

And in the groves and woods
Precipitately drive the fish to dwell.
