Just placed my order for a new bong, after my mom found my other one =( this time I went the not too expensive road in case something like that happens again. http://www.grasscity.com/media/cata...ab33525d08d6e5fb8d27136e95/g/p/gper_40-31.jpg http://www.grasscity.com/us_en/blac...olator-ice-bong-ashcatcher-emerald-green.html hope i can post gc links. ANyways I was wondering, what kind of interesting upgrades there are to bongs I can do? If any. I have a question about the diffuser and downstem, how do I get a replacement for that bong, it says 18.8/14.5 what does that mean? and if I want a custom type downstem what would I look for?
