00:00The Otis Skyrise Elevator plunges downward, violently compressing trapped air inside the
00:06concrete shaft. At 45 miles per hour, piston effect pressure builds rapidly, creating intense
00:13forces against the shaft structure. Venting the shaft through steel grates might seem logical,
00:18but it just unleashes hurricane force drafts. Counterweights utilize shaped aerodynamic
00:24profiles to manage airflow and reduce pressure accumulation inside the shaft.
00:30Smart engineering defeats the pressure trap before the Otis Skyrise Elevator plunges downward.
