The floating clouds are right beneath your feet~~ Glass balcony on the 103rd floor

Although the floating clouds are intangible, they are absolutely the things that people yearn for in 2010. Now we have a chance to trample them under our feet.

The Willis Tower in Chicago, USA is one of the local landmarks. The 103rd floor is very special because its balconies are all made of glass!!! Of course it also includes what's under your feet!!! Well, I admit my legs have already started to go limp, although the designers claim that these 4cm thick glasses can bear a weight of 5 tons, but this is the 103rd floor after all, over four hundred meters high. Floating clouds? Everything is like floating clouds.
