Shanghai Tower is the second tallest building in the world (632 metres) after Burj Khalifa skyscraper in Dubai (830 metres). Two young guys equipped with GoPro cameras and face masks entered into the building and started to climb while they are documenting every minute of it until the arrival to the top floor. Even there they did not stop, the two continued to climb the crane on the top floor (18 metres), without any safety equipment. What they did is illegal and could easily result in death. We would not recommend anyone to try this, but we have to say that their footage from this dangerous journey is really amazing.
Be ready to have your hands sweat, this is not something you see everyday. Enjoy watching!
