This insane roof climb video will have your palms sweat

(sorry for the Buzzfeedesque headline, but it’s true)

Vadim Makhorov (on Instagram) and Vitaliy Raskalov (on Instagram) are best buddies and just a little bit insane. They climb rooftops. Not just any rooftops but the highest in the world. Illegally of course and without ropes and hooks. So don’t try this yourself, these guys do it for you. And they document their journeys across the world for everyone else to see.

Recently, they climbed the world’s second tallest building, Shanghai Tower. It’s still under construction, so in addition to the building’s 650 meters, they added the crane that’s on top.

Watch, and have your palms sweat like I did.
