Highest Glass Floor of the World

Highest Glass Floor Of the World

If you're scared of heights, it may be time to look away now.

Floating on air: Visitors get their first view from The Ledge, four glass balconies suspended from the 103rd floor of Chicago 's Sears Tower

'It's like walking on ice,' visitor Margaret Kemp, from Bishop, California said. 'The first step you take you think "Am I going down?"'

Fearless: Anna Kane, five, spreads out on the floor of the 10ft square box which is 1,353ft up

Spectacular: She also enjoyed amazing views out across the city

John Huston, one of the owners of the Sears Tower , even admitted to getting 'a little queasy' the first time he ventured out on to the balcony. However, after 30 or 40 trips, he seems to have got used to it.

Thrillseekers: The boxes jut out four feet from the building and were specifically designed to make visitors feel as if they are floating

'The Ledge is the world's most awesome view, the world's most precipitous view, the view with the most wow in the world.'

The balconies are 10ft high and 10ft wide, can hold five tons, and have glass which is 1.5 inch thick.

Unfazed: Although some adults felt dizzy after experiencing the Ledge, children seemed to take it in their stride

Long way up: Even the floor of the platforms are glass - few were brave enough to look straight down

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.
