Zipping off the world's biggest urban zipline

For those readers who hate heights - you might want to look away now.

But if you live for adrenaline-charged action, you might have found your newest ‘must-do’.

Daredevil Devin Graham – or DevinSuperTramp as he is known to his millions of followers on social media – today posted a video of himself launching off the world’s biggest urban zipline in Panama City, before parachuting into the air.

The zipline stretches over 600 meters across the city, and is attached to the 243-meter high White Tower skyscraper.

It takes just a white-knuckling seven seconds to hit the ground.
