Russian Extreme Sport on 900ft Up

A terrifying video of a death-defying group of teenagers walking out on a beam 900ft up is a hit online.
The one-minute clip shows one girl carefully edging out on an iron girder above a distant forest below.
But she is soon trumped by a blond-haired boy who smiles at the camera before pulling off an even more spine-tingling stunt.
He slides out on to the bar before standing bolt upright at the end with his hands on his hips admiring the view.
One fan wrote: "I got scared just looking at the video. They got balls."
But another asked: "Why in the hell would you ever want to do something so stupid and pointless?"
