Big Cats / Slow Motion

07:07 Remarkable footage shot by a National Geographic crew who set up a camera on a 400-foot-long track — and tried to keep up with the cheetahs as they raced along at more than 60 miles per hour, chasing a piece of meat.  The camera shot 1,200 frames of video per second, fast enough that two seconds of a cheetah running all-out take two minutes to play.
