Vital Apparatus Vent



The Vital Apparatus Vent (simplier: Dropper) is the final component in the tube networks that delivers objects when activated, either by buttons or automatic replenishing.

In the Portal series, test subjects can shoot a portal underneath the vent so that the dropped object's momentum may be used to launch it. In the event of when the object delivered by the vent is destroyed in any way (incinerated, dropped in goo etc.), the vent will deliver a replacement of the object. In most cases, when activated a second time the object previously delivered will be fizzled.

Vital Apparatus Vents drop the following items throughout the Portal series, usually cubes:
 * Weighted Storage Cube
 * Weighted Companion Cube
 * Discouragement Redirection Cube
 * Edgeless Safety Cube

List of appearances

 * Portal
 * Portal: Still Alive
 * Portal: The First Slice
 * Portal 2

Trivia

 * In Test Chamber 6, the first time you press the button to drop a Cube, rather than the cube dropping from the Vital Apparatus Vent, various "garbage" is dropped, being an Edgeless Safety Cube, a Defective Turret, a Radio and a chair.
