“Cracking” glass panels on a lookout 72 meters above the ground in Qingyuan, a scenic city in southern China’s Guangdong province, are reeling in tourists for an unnerving walk on a “shaky” bridge high above a nearby waterfall.

There are novel visual and audio effects, resembling glass cracking, when a visitor sets his or her feet on the glass platform perched out from the cliff at the Gulongxia – Dragon Gorge – tourist zone. These tricks and sounds are triggered by sensors embedded on glass panels that can allegedly measure the weight of anyone approaching.

Glass panels appear to crack the moment visitors set their feet on them.

In a clip released by the local tourist bureau, people are seen shaking nervously and even calling to be rescued when the glass appears to “splinter” with high-pitched sounds from hidden speakers.

But the trick feature has also attracted criticism. What if glass panels really crack due to excess weight or some other problem? How can the maintenance staff inspect the actual condition of the bridge, one citizen asked, and how could they know when a real accident is happening?

Local papers in Qingyuan said the size of the new attraction, opened at the end of last month, was more than three times the renowned U-shaped Skywalk bridge at the Grand Canyon in Colorado. The three-ply glass panels used are 4.5 centimeters thick and each can withstand weight up to three tons, they said.

China News Service said investors behind the “sky bridge” have filed applications with Guinness World Records, claiming their bridge is the world’s longest and widest for a suspended structure.
