Ah 6 weeks ! That sounds about right. Pity I can't remember that Japanese lad's name I think you'd probably really dig him the most.From What I could gather, it seemed that she soaked the unused film in pee for about two hours, then left it to air dry for about 6 weeks. You have to then advance the film on a little bit to see that its fully dry, or if you're confident enough I guess, unroll it entirely in the dark and dry it that way. I'm not overly sure how you could guarantee its actually properly dry by just advancing a bit though...
Its more interesting than anything else, I'm not sure I'd chance it unless I was using an older camera that's already got a bit of wear and tear.
I think it could be this guy

Not much of his negative destroying turns up in this search though.
