How do I take the companion cube with me after the level “Cold Boot” in Portal 2?

In “Cold Boot”, on GLaDOS 7 — the first time I encounter a companion cube — the Material Emancipation grid is broken.

GLaDOS makes a point of pointing this out, and saying don’t take anything with you in her extra dramatic voice… which implies I should take the Companion Cube with me.

But I can’t figure out how to! I need the cube on the switch to open the door, and I don’t see any way to get the cube without closing the door to Floor 7.

Is this possible?


The wall past the emancipation grid (once you’ve gone through the door) will accept portals. Put one in there, get the cube and let the door close, and portal through.
