Highest Glass Floor of the World




Not content with having the tallest building in America , the owners of Sears Tower in Chicago have installed four glass box viewing platforms which stick out of the building 103 floors up.
The balconies are suspended 1,353 feet in the air and jut out four feet from the building's Skydeck

Inspiration came from the hundreds of forehead prints visitors left behind on Skydeck windows every week. Now, staff will have a new glass surface to clean: floors.
Architect Ross Wimer said: 'We did studies that showed a four-foot-deep (1.2 metres) enclosure makes you feel like you're floating since there's only room for one row of people, not two.'
The Skydeck attracts 25,000 visitors on clear days. They each pay $15 to take an elevator ride up to the 103rd floor of the 110-story office building that opened in 1973.
