The U-shaped walkway, which wraps around a cliff face on the Yuntai Mountain in China's Henan province, started exhibiting cracks on Wednesday morning, "sending tourists fleeing off the structure," the Post reports.
“I was almost at the end and suddenly I heard a sound," tourist Lee Dong Hai wrote on Chinese social media site Weibo. "My foot shook a little. I looked down and I saw that there was a crack in the floor."
Officials told Chinese media that damage was caused "by tourists who had dropped a thermos flask on the glass."
Looks like we'll be canceling our trip to that massive glass suspension bridge that just opened in China's Shiniuzhai National Park.
