Re: How to make smoke cold?
An easy start is to put your hose in the freezer for a while before hand, and any part of the hookah you want to put in the freezer can't hurt honestly but they heat back up pretty quick.
A little more advanced you can make mods to your hookah, for example, my ex-roommate fitted a rubber tube filled with the gel from an ice pack around the down stem between the bowl and where it connects to the base. He kept it in the freezer until he wanted to smoke. This only works if you can take off the little ornate decoration thingies around the downstem but it really worked well for like the first 15 mins of a sesh.
