I know this is an old thread, but i had my roor sitting on my floor and dropped a lighter, and somehow the lighter bounced off the bowl on its way down and now my bowl is stuck in the stem. The problem is with my bong, it isn't working now becuase I had to glue the stem into the bong from a previous accident. Hot water, personal lubricant, and butter haven't gotten me far. I can't seem to get the lube between the stem and bowl, any new hints?
