China's "Impossible" Glass Skywalks Are Already Cracking — Engineers Are Calling It a Scam

China's "Impossible" Glass Skywalks Are Already Cracking — Engineers Are Calling It a Scam China went from about 60 glass-bottomed bridges in 2016 to roughly 2,300 by 2019, and now those glass skywalks are reaching their 10th birthday. This video investigates China's glass bridge safety problem, from the Zhangjiajie Grand Canyon Glass Bridge, where tourists smashed the glass with sledgehammers and an SUV drove across it, to the Yuntai Mountain skywalk that cracked when a tourist dropped a mug. You'll learn how tempered laminated glass really works, why it's one of the strongest walking surfaces ever built, and the hidden danger most people have never heard of: nickel sulfide inclusions that can cause spontaneous glass breakage years after installation, and the heat soak test meant to catch them. We also cover the fake cracking glass floor at East Taihang, the 2021 Piyan Mountain wind incident in Jilin where panels were ripped from a suspension bridge, and why Hebei province shut down all 32 of its glass attractions. Are China's glass bridges actually dangerous, or is the real risk the missing standards, weak maintenance, and race to build the most terrifying attraction? If you've ever wondered whether a glass skywalk is safe to walk on, this is the full breakdown. Watch till the end to see the "three levels of failure" and why the oldest bridges from the boom may matter most.
