GLaDOS repeatedly does this as an attempt to mock the latter's weight, constantly disabling it after each use before she finally decides to lower the ceiling that Chell was trying to reach. In the single-player campaign, GLaDOS uses this feature in a different manner, instead, she purposely 'breaks' the Faith Plate herself while Chell is currently using it. When a Faith Plate fails to launch the user, it will emit a distress beacon, causing the blue lights on it to flash into orange repeatedly. Upon contact, these platforms fling Test Subjects (and any objects, such as Weighted Storage Cubes, Sentry Turrets, or Personality Cores) into the air with a 50,000 pound-foot force, allowing them to bridge massive gaps or place portals in otherwise inaccessible areas. It was discovered that these attributes were negatively affected. Created by Aperture Science from at least 1998, this catapult plate is part of a larger trust experiment designed to help Aperture Science discover whether the capacity for trust or solving problems could be affected by being catapulted into space.
