Stand on the button to activate the funnel and place a portal behind you and then on the opposite wall to bring the cube over to you. Press the red button to drop a cube onto a platform. The lift is broken so drop into the funnel and follow the path around to the next chamber which is actually chamber 15. Portal over to the exit, then replace the portals so the laser hits the receptor once more and opens the door. Bring the cube back up to the platform and use portals to line up the cube so that it hits the receptor above the door.

Portal over to the platform, get across to the other side and press the button for a cube. The higher receptor turns off the laser field. The lower laser receptor on the wall moves the platform. Walk onto it and remove the funnel to be lifted up to the exit. When the button is pressed the second lift will drop down. Place a portal under the funnel and on the chequered floor panel to lift the cube up to the button. Use a portal to move the cube deflecting the laser. Stand on the first lift and then remove the laser. Use portals to make the laser hit the receptor by the lifts. Place the regular cube on the chequered panel on the floor below the button in the roof. Portal out of the pit and take the regular cube with you. Use the laser cube to deflect the laser onto the white wall. Use the bouncer to bounce through the portals and across to a high ledge. Place a portal on the sloped panel with the target and the other above the laser. Use the cube to block the laser which stops the funnel. Place a portal on the sloped platform with the target to fling over to the ledge. Use the funnel to lift yourself up above the floor. This puzzle at first appears pretty tricky. Portal up to the walkway and make your way to the exit. Place a light bridge in front of the turrets, Walk around the back and place the cube on the button. Use the light bridge above the walkway and bounce up to the walkway. Drop down, pick it up and portal back up to the beginning. Press the red button and use light bridges to stop the cube going through the barrier. Place the cube on the red button and head through the exit. Press the red button and the cube will get bounced over to the funnel. Use portals to fling yourself over to the exit and then place the funnel back in the center. Place the funnel in the center and bounce over to it. Use the funnel to remove the cube from the button and then funnel up to the exit. You can now take the funnel to the other side. Grab the cube and place it on the red button. Standing on the red button reverses the direction of the funnel. Then use the funnel to bring the cube over to you. Use the funnel to remove the turret to the left. Head through the exit to the next chamber. Place a funnel going up, and then across to the exit so that the cube hits the button on the wall. Place the funnel in front of the target and bounce over to it. One the cube is in line with the panel on the opposite side replace the second portal so the cube floats towards you. Place the funnel under the cube dispenser and then press the red button. Wait for Wheatley to get the chamber set up and then use the funnel to float across to the other side. Use the funnels to bring it over to you and then use a funnel to place the cube on the button on the roof. Place the funnel under the dispenser and press the red button to release a cube. YouвЂ™ll float up to a ledge with a red button. As you float through and back to the original funnel place the second portal on the ledge to the left. Float up to the higher room and go through the exit.Дrop into the funnel and place a portal on the wall opposite and one on the side wall. Release the cube so it lands on the button in the roof. Place the second portal on the ground with the checkered marks and float through the funnel. Step out onto the ledge and grab the cube. Place a portal at the top and once you float through the hole in the glass place the second portal on the side wall so the funnel goes past the ledge. After this Wheatly will find some real testing chambers. Wheatley will make you take this test twice so do the same thing and head through the exit. Press the button and portal over to the other side. Go through to WheatleyвЂ™s first attempt at a testing chamber. Place a cube on the red button to complete the test.

Portal through the broken grate at the back of the office and make your way around to the testing chamber. Wheatley is trying to test his new cubes but theyвЂ™re just not cutting it.
