A video has surfaced online depicting a seemingly fearless group of teenagers walking across a steel beam atop a 900-foot-tall tower.
The one-minute clip, embedded, below, shows a red-headed girl edging out on a girder, buildings and trees visible in the distance below.
But the camera quickly swings around as a boy, cheered on by friends, makes his way to the end of a separate beam before rising to stand completely upright.
There is no explanation as to where they are or how they got up there.
The accompanying blurb posted alongside the YouTube video reads: "New Entertainment style for your kids in Russia ... I can't watch anymore cuz my teeth started to itch."
