Polar bears destroy robot spy cams, show no remorse (video)

Iceberg Cam, Snowball Cam, Blizzard Cam and Drift Cam were the arctic photographer's best friends -- high-tech spy robot cameras designed to resist cold and traverse sub-zero terrain. Then they got crushed to death by giant polar bears while attempting to make friends. Seriously, that's the basic gist of Polar Bear: Spy on the Ice, a new BBC documentary which began airing last week, and which just so happens to be narrated by David Tennant. Hope he's got a screwdriver handy, if you know what we mean. Watch the bears play a spirited match of robot football after the break, then see all the lovely mechanical carnage in a third video at our source link.
