If there's one thing that the BBC's new nature documentary "Polar Bear: Spy on the Ice" teaches us, it's that polar bears are naturally inquisitive — and rather unforgiving when it comes to spy cameras.

Engineers were tasked with creating some rather clever spy cams to get up and personal to the bears in their natural habitat. While they certainly succeeded (some are shaped as small pieces of floating ice or giant snowballs), they may have underestimated just how intelligent the bears really are.

From the The Guardian's review of the television special: 

"Maybe they just want to make Tennant eat his words, the ones he said about the spherical design of Snowball Cam making it almost indestructible. Indestructible? Pah! They break it open, easy as an egg. And the others, Snow Cam, Blizzard Cam, one by one – £130,000 worth of equipment, smashed to smithereens. Or perhaps it's payback time, against mankind. Huh, you destroy our habitat, we destroy your stupid cameras."
