Link to making your own carbon scrubber

I saw a link on making your own carbon scrubber with pics, instructions, etc. I think it was in 101 questions but now I can't find the damn link. I've done several searches and still can't find it. I remember it was posted by Widow Maker. Can anybody help? Please.

Sorry everybody, I found it. What a dumb ass. It was in 101 question but the heading was How to make a cool tube and under that it says how to build your own scrubber.
