Corryvreckan Maelstrom

Corryvreckan Maelstrom in Scotland is very powerful permanent whirlpool just off the coast of Scotland. Complex tidal forces and the unique geological formation combine to create an incredibly powerful, perpetually spinning whirlpool of death. A documentary team once equipped a mannequin with a life jacket and a depth gauge and then tossed it into the Corryvreckan. When it was eventually found, the depth gauge had a maximum reading of over 650 feet and it was severely damaged.
