The '''Aperture Science Unstationary Scaffold''' is a testing element featured in several Test Chambers of the Aperture Science Enrichment Center|Enrichment Center.

==Overview==

*Moving along a blue ray similar to the one moving the elevators linking the Test Chambers, this moving platform is often used to go across toxic waste located below.

*It can be activated by sending an Aperture Science High Energy Pellet in its catcher, or putting a Weighted Storage Cube on a 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button|Super Button.

*Before the device starts itself, a mechanism lowers the platform towards the blue beam.

*As seen on FileBorealis plans 02.png|one of its blueprints, the ''Borealis'' contains an Unstationary Scaffold.
* In the commentary for Portal, a developer says that originally the scaffolds ran on solid tracks, but they changed it because players would run on the scaffold. The new version would have killed Chell if she touched it, but playtesters found that solution frustrating. The developers changed it to run on "Immaterial beams of light".
*Unstationary Scaffolds can also travel downwards, as seen in Chamber 19, where it goes lowers at an angle into the pit of fire.
