A glass floor is a transparent section of a floor, found most often in buildings (usually in the observation decks of towers) or boats in order to facilitate viewing directly beneath where one is standing.
Usually made of a reinforced glass, the most common use is as a tourist attraction. Glass-bottom boats are popular for allowing a better view into the water. Glass as a flooring material is used in both residential and commercial structures. Special hollow glass blocks known as glass pavers are often used in combination with a metal frame.
At 4000 feet (1219 m), the highest glass floor above ground is the novel outdoor application of the Grand Canyon Skywalk, operated by the Hualapai Indian tribe. The highest above ground level in a freestanding structure is in the CN Tower in Toronto, Ontario at 1122 feet (342 m).

Famous quotes containing the words glass and/or floor:
“Nor do I try to keep a garden, only
An avocado in a glass of water—”

“Four and twenty at her back
And they were a’ clad out in green;
Tho the King of Scotland had been there
The warst o’ them might hae been his Queen.
On we lap and awa we rade
Till we cam to yon bonny ha’
Whare the roof was o’ the beaten gold
And the floor was o’ the cristal a’.”
