Three students in Hong Kong have posted a stomach-churning selfie taken from the very top of a skyscraper.

Billed as the "World's scariest selfie" on You Tube, the video shows Daniel Lau and two friends atop a towering skyscraper eating  bananas.   Lau used a "selfie stick" to get the dizzying footage of the adventure 1,135 feet above the streets of Hong Kong dangerously perched on the spire of The Centre skyscraper, Hong Kong's fifth-tallest skyscraper.
