Afraid of heights? This pool in Downtown Houston isn't for you. The pool atop of the Market Square Tower is called "Sky Pool." The pool extends 10 feet off of the side of the 42-story tower allowing swimmers to walk on it's 8" thick plexiglass bottom looking directly down at the street.
Would you dare swim off the edge?
