What starts out looking like a normal and potassium-filled selfie turns into an acrophobia's nightmare.

Photographers Daniel Lau, Andrew Tso and an unnamed friend took an incredibly dangerous, yet casual selfie atop the the Centre in Hong Kong, a skyscraper that tops out at 1,135 feet.

This isn't the first time the team has taken a risky shot though, Tso's website has a collection of dangerous photographs taken from staggering heights.

Hopefully they didn't slip on those banana peels on the way down.
