The buildings ' architecture , as wells as many of the window panes , fixtures , and other accents , would draw oohs and ahs from architectural historians , but not from people educating 11-to-14-year-olds . Now , visitors have to look down through a window at the end of the 2nd floor corridor . This building has also been used to test mailrooms to protect against package bombs , windows and window retrofit methods , and will hold various walls for additional blast testing . However , such vulnerabilities are only useful for attackers if the advertised parameters change during the window .
