This is the seventeenth level of the game, and is the final part of Chapter 2. The level takes place within a dilapidated Test Chamber, and requires the player to circumvent a large [[Emancipation Grid]] and successfully activate a [[Thermal Discouragement Beam]]'s receptacle using a [[Discouragement Redirection Cube]].

*Wait for GLaDOS to finish rebuilding the chamber.

*Press the button to release a [[Discouragement Redirection Cube]].
*Fire a portal though the hole in the glass, and one to your right.
*Walk into the portal and grab the Redirection Cube, then walk back though the same portal.
*Use the Redirection Cube to aim the [[Thermal Discouragement Beam]] toward the receptacle.

[[Image:Portal 2 Chapter 2 Test Chamber 08.png|left|300px|Test Chamber 08]]
This chamber uses [[Material Emancipation Grill]]s within the test itself. (which [[GLaDOS]] claims was to make up for the previous chamber's grid malfunctioning.) Partway through, the turbines develop a problem(s), prompting [[GLaDOS]] to step out until the next chamber. Before doing so, she gives a fast-version "explanation" of the test. (The "explanation" is actually an excerpt from Moby Dick.)

This is the sixteenth level of the game, and takes place within a dilapidated Test Chamber. This level requires the player to utilize their knowledge of the [[Thermal Discouragement Beam]], [[Button]]s and momentum in order to successfully solve the Test Chamber. This level is also unique in that it features a damaged [[Emancipation Grid]], which allows the player to unlock the "Preservation of Mass" achievement. The [[Weighted Companion Cube]] is also introduced here.

== Hazards ==
*[[Thermal Discouragement Beam]]

== Walkthrough ==
{{Spoiler|block=yes|
*Proceed to the chamber, jump over the Thermal Discouragement Beam and pick up the [[Companion Cube]].
*Look up and wait for the second companion cube to fall. When it does, pick it up and block the beam with it (it will fizzle).
*Wait for the third cube to fall and take it to the beam to block it. Lift on the opposite side of the entrance will descend.
*Get on the lift and place a portal under the cube and other one on the wall to get the beam connected again.
*Wait for the lift to get to the top.
*Place a portal on the angled panels further away and walk over there. Place the other portal under the cube, so it'll come out near you.
*Pick up the cube and jump through the portal on the floor. Place the cube on the [[Heavy Duty Super-Colliding Super Button|button]].
*Place a portal on the other angled panels on the far-left corner and then place the other portal on the floor.
*Jump through the portal on the floor and go to the [[chamberlock]].
}}

== Video walkthrough ==
{{walkthrough}}

== Trivia ==
* Use the Companion Cube to block the beam then run to the wall by the victory lift and you can pull Wheatley from the wall.
** He will not activate the button nor talk to you, but he can be used to block the beam if dropped face down.

* Placing the companion cube on the button after collecting Wheatley and using momentum to fling yourself to the exit will cause GLaDOS to say: [[Media:GLaDOS sp_a2_pit_flings_future_starter01.wav|"Uh oh. You're stranded. Let's see if the cube will try to help you escape. Actually, so that we're not here all day, I'll just cut to the chase: It won't. Any feelings you think it has for you are simply byproducts of your sad, empty life."]].
** She will then fizzle the cube on the button thus releasing a further cube form the Vital Apparatus Vent and say: [[Media:GLaDOS sp_a2_pit_flings_future_starter02.wav|"Anyway, here's a new cube for you to project your deranged loneliness onto."]] This can happen without grabbing Wheatley if you take the cube past the broken emancipation grill, leave it in, jump off of the platform where the exit door is, and place both portals on a nearby wall.

* If you place a portal on the wall past the broken [[Material Emancipation Grill]], you can then retrieve the Companion Cube. However, when you near the [[Chamberlock]], GLaDOS will fizzle the cube and say [[Media:GLaDOS sp_a2_pit_flings06.wav|"I think that one was about to say 'I love you.' They ARE sentient, of course. We just have a LOT of them."]]

[[Image:Portal 2 Chapter 2 Test Chamber 07.png|left|300px|Test Chamber 07]]
This chamber features a brief reappearance of the [[Weighted Companion Cube]]. [[GLaDOS]] destroys two of them at the start; first when [[Chell]] tries to pick it up, and second when the cube is placed in the laser's path. This chamber, like [[Portal 2 Chapter 2 Test Chamber 2|Chamber 02]], features [[Wheatley]] peeking in from behind a raising platform. At the end of the chamber, the [[Material Emancipation Grill]] is malfunctioning. This allows [[Chell]] the opportunity to take the Companion Cube with her. (awarding the player the "Conservation of Mass" achievement.) However, doing so results in the cube being destroyed a third time. [[GLaDOS]] then contradicts her original statement from Portal about the Companion Cube being non-sentient.

This is the fifteenth level of the game, and takes place within a dilapidated Test Chamber. This level introduces the player to advanced manoeuvres using [[Aerial Faith Plate]], particularly the way in which the momentum provided by the Faith Plate can be used in conjunction with [[Portals]] in order to allow the player to gain access to areas that would otherwise be beyond reach. {{Spoiler|The Test Chamber also features one of the Rat Man's [[dens]].}}

== Walkthrough ==
{{Spoiler|block=yes|
*Walk towards the left of the chamber, then look back to the right to spot two angled portal-conductive surfaces. Place a portal on each platform.
*Walk back to the entrance of the chamber and use the Faith Plate there.
*Once at the destination, press the [[Switch|switch]] to release garbage onto the initial [[Aerial Faith Plate]]. When instructed, press the button again to release a [[Weighted Storage Cube]]. While facing the direction of the switch, note the [[Heavy Duty Super-Colliding Super Button]] to the bottom left.
*When the Cube arrives, place it on the Button by placing a portal above the Button, and then dropping the Cube through the portal.
*The exit door will now open, proceed into the [[Chamberlock]].

It is also possible to solve the chamber by activating the button with an Edgeless Safety Cube that GLaDOS drops as part of the garbage pile. But this can only be achieved once and the original solution is more recommended.

This test involves more advanced use of [[Aerial Faith Plate]]s. The main objective is to use the momentum of the Faith Plates to put a [[Weighted Storage Cube]] on a [[Heavy Duty Super-Colliding Super Button|button]] on a ledge.

Before the [[Weighted Storage Cube]] can be received through the [[Vital Apparatus Vent]], several items from [[Portal]], from later areas or from the co-op campaign drop out, including a chair, a Defective Turret, two Edgeless Safety Cubes, a working radio, a water bottle, and a CD or disc. Unlike previous encountered radios, the radio in this chamber plays [[Still Alive (song)|Still Alive]], like the radios in Portal. Getting the radio to the Ratmann Den in the chamber causes it to play a hidden transmission, which unlocks the Final Transmission achievement.

Getting the Weighted Storage Cube onto the button without touching it will unlock the Drop Box achievement.

This test involves more advanced use of [[Aerial Faith Plate]]s. The main objective is to use the momentum of the Faith Plates to put a [[Weighted Storage Cube]] on a [[Heavy-Duty Super-Colliding Super Button|button]] on a ledge.

Before the [[Weighted Storage Cube]] can be received through the [[Vital Apparatus Vent]], several items from [[Portal]], from later areas or from the co-op campaign drop out, including a chair, a Defective Turret, two Edgeless Safety Cubes, a working radio, a water bottle, and a CD or disc. Unlike previous encountered radios, the radio in this chamber plays [[Still Alive (song)|Still Alive]], like the radios in Portal. Getting the radio to the Ratmann Den in the chamber causes it to play a hidden transmission, which unlocks the Final Transmission achievement.

Getting the Weighted Storage Cube onto the button without touching it will unlock the Drop Box achievement.

This is the fifteenth level of the game, and takes place within a dilapidated Test Chamber. This level introduces the player to advanced manoeuvres using [[Aerial Faith Plate]], particularly the way in which the momentum provided by the Faith Plate can be used in conjunction with [[Portals]] in order to allow the player to gain access to areas that would otherwise be beyond reach. {{Spoiler|The Test Chamber also features one of the Rat Man's [[dens]].}}

== Hazards ==
*[[Goo]]

== Useful Items ==
*[[Aerial Faith Plate]]
*Switch
*[[Weighted Storage Cube]]
*[[Heavy Duty Super-Colliding Super Button]]

== Walkthrough ==
{{Spoiler|block=yes|
*Walk towards the left of the chamber, then look back to the right to spot two angled portal-conductive surfaces. Place a portal on each platform.
*Walk back to the entrance of the chamber and use the Faith Plate there.
*Once at the destination, press the [[Switch|switch]] to release garbage onto the initial [[Aerial Faith Plate]]. When instructed, press the button again to release a [[Weighted Storage Cube]]. While facing the direction of the switch, note the [[Heavy Duty Super-Colliding Super Button]] to the bottom left.
*When the Cube arrives, place it on the Button by placing a portal above the Button, and then dropping the Cube through the portal.
*The exit door will now open, proceed into the [[Chamberlock]].

It is also possible to solve the chamber by activating the button with an Edgeless Safety Cube that GLaDOS drops as part of the garbage pile. But this can only be achieved once and the original solution is more recommended.

*Use the [[Aerial Faith Plate]] to reach the other side of the chamber
*Use the [[Switch|switch]] to release a [[Weighted Storage Cube]], observe how it is repeatedly launched by the Faith Plate in the middle of the chamber.
*Use the Faith Plate to launch yourself towards the Cube in order to grab it; time yourself so that your trajectory intersects with that of the Cube's.
*Once the Cube is obtained, use the Faith Plate to return to the exit door of the chamber.

Introduces the [[Aerial Faith Plate]] testing element. [[GLaDOS]] claims that they were invented to see "how well Test Subjects could solve problems whilst being catapulted into space." The results showed "they could not." (ironically, the scenario was actually the reason for the [[Excursion Funnel]] being invented.) After the test, [[GLaDOS]] states that [[Chell]]'s air supply is actually "freshened" carbon dioxide.

This is the thirteenth level of the game, and takes place within a dilapidated Test Chamber. This level continues to use the [[Thermal Discouragement Beam]] as its primary [[mechanic]], and demonstrates the way in which interrupting the Discouragement Beam can be used to the player's advantage. The Test Chamber also introduces the [[Unstationary Scaffold]], and Goo is present as the primary environmental hazard.

== Walkthrough ==
{{Spoiler|block=yes|
*Once inside the test chamber, look straight ahead to find a [[Switch|switch]] against a wall. Place a portal on the wall to the immediate left, and the opposite portal on the wall near the switch.
*Once through, press the switch to release a [[Weighted Storage Cube]].
*Place a portal on the wall where the [[Thermal Discouragement Beam]] makes contact. Ensure that this portal is opposite to the colour placed on the wall to the left of the chamber entrance. If done correctly, the beam will make contact with the receptacle, and the [[Unstationary Scaffold]] will move towards the platform with the button.
*Once on the platform, use the cube to block the beam temprarily in order to manouver around it. Once on the other side, pick up the cube once more, and place it on the [[Heavy Duty Super-Colliding Super Button]] to open the door to the [[Chamberlock]]
