A few weeks ago, the John Hancock Center building in Chicago reopened its 94th-floor observatory and introduced its new attraction called "Tilt."
This fear-inducing "architectural achievement" works basically like this: a series of floor-to-ceiling glass windows, each holding a visitor, slowly tilts out 1,000 feet above Chicago's Michigan Avenue, offering the brave souls a white-knuckle view they won't soon forget.
It's advertised as "a new angle on Chicago!" but it looks more like a one-way ticket to a serious case of vertigo.
See what you think. Watch these two videos of it in action.
