This chamber is very simple. The goal here is to get through the other side of the room which is separated by glass.

1st room has 2 buttons, 1st door and transparent glass on the left. 2nd room has 3rd button and both doors. 3rd room doesn't have any buttons but has a portable surface and 2nd door.

1Enter the chamber and place your first portal on the surface directly to the right as you enter the room.
2Stand on the button directly in front of the entrance to open the door just ahead of the button.
3Head through the door and into the small corridor behind it.
4As soon as Blue is through the door, step off the button and head left to the second button to stand on that one which will then open up the exit door from the corridor which Blue is in.
5Walk through the newly opened door and place an exit portal on the wall to the right of it.
6You then simply need to walk through the first portal to make it to the area near the exit door and so both players can easily finish the chamber.

Difficulty: Easy
How to obtain: Course 1, your friend needs to place portals next to eachother on the floor, which is under a ceiling where you can place your portal. Shoot a portal next to your friends portals and the other one on the ceiling facing one of your friends portals. Fall through your portal and when you go through one of your friends portals, you'll be facing the ceiling again. Then you must shoot the portal on the ceiling to the place where you are about to go. Then wait for a while as you are falling through the portals and the achievement will appear. Alternatively. in Hub, let your friend place portals next to eachother on the 2 by 2 floor. Go through friend's portals and keep poping to friend's portals. While you are in mid-air, places portals where friend's portals placed on. Can also be done using a reversible Excursion Funnel, just like Air Show.
