ballin, I'm also pretty sure the Stem of the VaporStar will fit snuggly/air tight in most glass bong STEMS so you would then have a true vapeing bong. For instance Mini Glass Bong and if you placed your Vaporstar in the top of this bong you'd get just enough friction to make it air tight and allow for VONG hits(hey maybe I just coined a new term "VONG HIT'S" - oh well probably not) anyway when I get more funds I may just do that, all you need really is a down stem that the VaporStar will fit into and then just put it in the VaporStar bong since the stem hole size is the most common on the market.
