re: Skyscraper in Shanghai lets visitors walk on glass walkway without handrails

I did the acrylic cages in what used to be the Sears Tower in Chicago.

It was pretty cool, until I felt it shaking all of a sudden.

I kid you not this entire family of morbidly obese people stepped onto it, and I thought the whole thing would collapse. I promise you the lightest one of the four was still north of 300 pounds. Perhaps they're just used to the ground swaying beneath them.
