Beware of the Big Brinicle of Death

The Brini­cle of Death. It has nev­er been cap­tured on film … until now. And it’s all on dis­play cour­tesy of the BBC series Frozen Plan­et.

In a nut­shell, a brini­cle forms when cold, dense brine comes into con­tact with warmer water. It all starts on the ocean’s sur­face, and then the emerg­ing brini­cle (oth­er­wise known as an ice sta­lac­tite) starts to move down­ward, form­ing some­thing of a sub­merged tor­na­do, until it even­tu­al­ly hits the ocean floor and freezes every­thing in its path. The video above takes a 5–6 hour event and reduces it to a crisp, kind of hair-rais­ing two min­utes.
