An American thrill-seeker has successfully completed a 1,800-metre-high slackline stunt across China's Enshi Grand Canyon - without any safety equipment.
Dean Potter, 40, crossed the 41-metre long rope in three minutes without a parachute or a safety harness.
He even managed to listen to music on his headphones on the stomach-churning way across the slackline, which is reportedly even more dangerous than a tightrope as it can bounce or stretch at any point.
Dean is well-known in the extreme sports field, and even starred on Channel 4's Daredevils.
See the footage below - we dare you not to wince at the wobbles...
