TILT Attraction At Hancock Center, Chicago

A leaning 1000ft-high viewing platform has been installed at the John Hancock Center skyscraper in Chicago - offering brave visitors a spectacular view of the city's streets. TILT is housed on the 94th floor of the towering building and allows tourists to clutch onto a steel and glass panel, which slowly disengages from the floor and moves forward at a 30 degree angle, leaning down over the street below. Those afraid of falling through the glass need not worry - there are three layers of tempered glass between tourists and the ground 304 metres below. The attraction costs $5 plus general admission to the 360 Chicago observation deck (formerly the John Hancock Observatory), which is $18 for adults and $12 for kids.
