Forget extreme sports, it's now time for extreme selfies. Meet friends Andrew Tso, Airin S and Daniel Lau who take the stick selfie to the next level by posing on top of Hong Kong skyscraper The Center.
When Daniel Lau posted the video below on Instagram, it went viral almost overnight. And why wouldn't it? They demonstrate their dare-devilry, show you an amazing aerial view of Hong Kong and get your heart racing all in under 20 seconds. The three seem so calm, even at a height of 346 m (1135 ft), you'd think they were chilling on your next door neighbour's terrace. Only, they are so not.
Call them brave or 'bananas', we leave that to you. We however wish there was a video of them making that scary climb.
