CN Tower Glass Floor
Toronto's CN Tower has several thrill-inducing features. The first and most accessible is a glass floor on an observation deck that's more than 1,100 feet above street level. People can stand and sit on the glass, which is only about 2.5 inches thick. Despite its thinness, the CN Tower claims the glass could hypothetically hold 35 adult moose.
The tower also has a glass-floor elevator and a skywalk, called the EdgeWalk, which is similar to the walkway around the top of the Auckland Sky Tower.
