For a team of gravity-defying parkour runners known as Storror, Hong Kong is one big playground.
In the latest gut-wrenching video uploaded on Instagram, team member Max Cave appears to make a life-or-death leap from the roof of one towering skyscraper to next over a nausea-inducing chasm. The post has gained over 253k likes.
TIME has not authenticated the video.
With a following of 85.2k on Instagram, the U.K.-based Parkour team consists of eight daredevils who scale and jump over roofs and skyscrapers worldwide, from Israel to Sweden to Turkey.
If your stomach can handle the leap of faith, the team of adrenaline junkies has plenty more videos on YouTube.
