Its weird that I came accross this thread. I was debating buying the stoners everybody mentions, so I did some newsgroup browsing on Google Groups, and saw this exact same solution (no pun intended... well maybe I guess ). Seeing as how we have a half-gallon jug of vinegar laying around, I think I'll give it a shot. Now I really have a reason since many people here have been amazed. I think I'll add some rubbing alcohol for sure though.
