Set your first portal on the wall to the left of the laser beam at the back of the room, then jump over the beam and turn around to your left and walk into the corner.

Look for the Displacement Cube and drop your second portal right underneath it so it falls out of your first portal (by the laser).

Pick up the Cube and jump back over the laser, before positioning yourself so you’re reflecting the beam into the square panel on the left-hand wall.

Drop the cube on the ground once you’ve lined the beam up and a set of stairs will reveal themselves from the ground just up and to your right. Walk up here and then look down at the ground (just to the left of the red button).

Place a portal here and then turn around and look at the Displacement Cube, place your second portal here and it’ll appear near you, so turn around, pick it up and drop it on the red button to open the exit.
