This is the fourth course in the Portal 2 co-op campaign. Things start to get difficult with these puzzles. Trying to completed these chambers without dying is a nice little challenge that can chew up an hour or two.

These video guides should make things easier for you.

Note: I couldn't find split-screen videos, but I will update this solution once I find some.
