So I was at a New Years festival today and I see this guy hitting something. Thought it was a mod at first but the more I looked at it the more I thought it was for herb. Still not sure so I figured id snap a pic or two to see if anyone can ID this thing. Anyway, it took him a minute or two of hitting it to get it going. Only saw one real cloud but it came out pretty thick. Then again I wasnt watching too long. Its for sure flameless though. Sort of looked like a polished steel pipe (the combustion kind) with hammer style end? Any ideas?
