How to Solve Test Chamber 08 in Portal 2

When you first enter Test Chamber 08, GLaDOS will immediately tell you the solution, but unfortunately, she does it by rattling it off at super speed. As usual, she’s little help here. Instead of relying on her, head into the upper area of the chamber through the emancipation grid. Here, you’ll see a laser, a button, and a small hole in the glass behind the button. Ignore the laser for now and push the button. This will cause a Redirection Cube to fall from the ceiling on the other side of the emancipation grid. Because you can’t walk the cube through the grid, you’ll need to use portals to get it through.

Shoot a portal through the hole in the glass onto the wall on the other side of the room. Then, put a portal on the wall behind you. Walk through the portal on your side of the chamber and grab the cube with the X button.

With the cube in hand, head back through the portal you just exited and use the cube to redirect the laser so that it hits the laser target on the wall, unlocking the door.
