Re: O NO!! HELP!
jb weld or an epoxy, just check it and or get the MSDS of it and see if it will off gas at all after a short period of time (off gassing being the release of chemicals in to the air which is not a good thing if you are going to be breathing it in all the time). i would try to find something that is "food safe"
if youve never soldered before i wouldnt suggest doing it now on such a delicate project, you could always find a jeweler or a metal worker that knows what a hookah is that could help you
