Want to walk in the air? Well you can by walking on the highest-ever guardrail-less glass skywalk outside the sightseeing hall of the 88-storied Jinmao Tower, one of the landmark skyscrapers in Shanghai.

Standing at 340.6 meters high, the skywalk, which is 60 meters long and 1.2 meters wide, will open to public on Thursday.

Visitors who want to walk on the skywalk reportedly have to sign a statement confirming they have enough physical and mental strength to take part in the activity, and that the activity will not do any harm to their physical and mental health.
