(CNN)If spectacular heights give you that sinking feeling, then this is not the swimming pool for you.
Glass-bottomed pool 500 feet above downtown Houston
A video of a new cantilevered glass-bottomed infinity pool, hanging off the 40th floor of an apartment building in downtown Houston, has gone viral.
The clip shows a brave soul slipping their bare feet along the pool's eight-inch-thick plexiglass bottom, which sits out 10 feet from the side of Market Square Tower.
It's being billed as the tallest pool in Texas and the only glass-bottomed pool in Houston.
Viewers around the world are split between wanting to plunge right in or grab their towel and run.
Anyone wanting to try it will have to befriend a resident though. The pool, which opened in October 2016, isn't open to the public.
The pool was designed by Kudela & Weinheimer Landscape Architects and is the centerpiece of a wraparound rooftop terrace with views of the Houston skyline and Buffalo Bayou Park.
For less gung-ho residents, there's a second resort-style pool on a lower terrace. It's not the only Houston pool to make a splash recently.
The 1,000-room Marriott Marquis Houston, which opened in December 2016, has a Texas-shaped lazy river and an infinity pool on its rooftop, 110 feet above street level.
And if you're looking for apartment buildings with that added extra, you could always try Chongqing, China.
The southeastern city has been getting creative with its housing and transport solutions to accommodate its 49 million residents.
There's a new 19-story apartment building which is not only close to the train station, but has a light-rail passenger train passing right through its middle.
There's even a transit stop inside, on the sixth through eighth floors.
