Anyone with a fear of heights should look away now.
Or at the least, make sure they don't end up on the flying saucer-shaped glass viewing panel that opened last month on the outskirts of Beijing.
But daredevils are flocking to the world's largest glass sightseeing platform, which has a circular surface area of 415 sq m.
Jutting out 33m over the cliff edge in Jingdong Stone Forest Gorge in Pinggu district about 70km from Beijing, the platform is said to be the longest in the world.
It was built using aviation-grade titanium, the first time the alloy material has been used to build a structure like this. The material allows it to be relatively light as well as strong and corrosion-resistant.
The enormous structure is composed of a glass-bottomed walkway leading to a circular viewing platform that gives visitors a 360-degree view of the scenic area, and of the 400m-deep valley below them.
Thousands have flocked to the viewing platform to overcome their fear of heights in return for the million-dollar views.
