Test Chamber 02 introduces the Weighted Storage Cube and the concept of using objects to activate buttons. You'll find a Weighted Storage Cube in this chamber. Your goal is to place it on a large red button to open the exit door. First, use your single blue portal to reach the platform where the cube is located. Once you've retrieved the cube (by pressing 'E' to pick it up), you'll need to transport it to the button. Place a blue portal on a wall near the button, then place another blue portal on the platform where you are. Walk through the portal with the cube to transport both yourself and the cube. Place the cube on the button, and the exit door will open. Proceed to the next chamber.
