This post gives directions on how to complete test chamber 08 in the game Portal. This Test Chamber is about halfway through. It is not as much of a challenge in comparison to later test chambers in the game. For those that need help, below is I give instructions to aid in the completion of the level. It will be demonstrate with pictures and a short description of what to do.
I have compiled this all in a one minute video walking through the steps which can be viewed here. If you find yourself to be stumped looking at this picture only, then perhaps the video will help. Happy gaming!
