China is quickly becoming known for its affinity for terrifying glass bridges. After reading this article, however, you'll likely have second thoughts about crossing any of them.

Only two weeks after it opened to the public, a section of the cliff-side glass walkway at Yuntai Mountain scenic area in China's Henan province developed cracks under the feet of tourists.

"When I was almost at the end (of the walkway), there was a sudden loud bang and a tremor beneath my feet," a tourist told the state-run China Net. The cause? A simple stainless steel cup that was accidentally dropped.

As word of the cracks spread, visitors began fleeing the bridge, which offers spectacular-yet-horrifying views of the canyon floor more than 3,540 feet below.

"I looked down and saw the glass floor beneath me shattered," the tourist added. "[I have] no idea why it happened, at that moment everybody was screaming. I yelled out loud 'It cracked, it really cracked!', then pushed the people in front of me to leave. [I was] terrified."

Officials investigating the cracks say people were never in danger, as only one of the three layers of reinforced glass reportedly cracked. Oddly, however, it appears that the falling mug struck a particularly vulnerable point that then spread more cracks along a 223-foot section of the bridge. (Wow. Can you imagine if that person dropped a giant stainless steel thermos instead of a mug?)

You can see the section that has been shut down in the drone footage below. Officials have yet to announce when the site might be expected to reopen, not that we have any interest in going!
