Pay no mind to GLaDOS’s assurances about this test being unsolvable—”she” is just trying to fulfill the psychological portion of Test Chamber 09’s exercise. You have to get creative, however, since you can’t simply bring the Weighted Storage Cube through the Material Emancipation Grid without disintegrating it. Likewise, if you place a portal behind the grid and walk back into the main room, your portal will disappear. Here’s how you meet the challenge: First, fire a blue portal directly below the Vital Apparatus Vent. Pick up the cube that’s on the ground and bring it through the portal. You’ve just emerged from the orange portal atop the elevated platform to your left. Leave the cube near the orange portal—you’re going to have to reach in and grab it momentarily.
Now walk through the grid, deploy another blue portal, and grab the cube. You have officially foiled Aperture Science’s Material Emancipation Grid technology. Place the cube on the button and exit the chamber.
