Player blue will need to launch themselves off the ledge and jump on the two patches of jumping gel to get to the other platform. Player orange will then need to met up with player blue and head over to the large red button, this will extend the platforms ahead. (player orange will need to press the button once again). Once there is blue gel on the floor they will need to shoot another portal back onto the white panel on the floor to let some gel out. Player blue will then need to move the portal on the ground to the panel on the side of the wall. Player orange will then need to push the button. Player orange will then need to shoot their portal below the gel pipe and another portal on the white panel above the force field. You will see the grill in front of you, you will need to shoot a portal on the white panel behind the grill, then shoot the second portal on the white platform below.
Head over to where you shot your portal and use the gel to get up onto the platform. Player blue will then need to head over and press the button. To start off, player blue will need to shoot and place their first portal below the gel pipe, they will then need to shoot their second portal on the sloped panel located on the top left hand corner.
