This is a video taken from the top of the Burj Dubai, the tallest building in the world, at 2,684 ft. Jesus, that's half a mile. Can you believe humans are even capable of this? I can't -- I shit my swim trunks on the high dive once. But, to my credit, I did do one hell of a cannonball.

Thanks to Rick, who has dived off higher platforms into a cup of water. I mean, he died, but he did do it.
