‘Brinicles’ are icy fingers of death

Brinicles form because of the peculiarities of super cold ocean water … Sea ice forms with channels through which highly salty water flows downward toward the bottom. The very cold, very salty water freezes the warmer, less salty water slowly creating a giant tube through which the freezing water flows.

Eventually, the tube touches bottom and the freezing touch extends outward, killing anything in its path.

Pretty freaky to watch the time-lapse video…
