Re: Keeping the water cool !
I have noticed a difference primarily when a tobacco containing mint is used. The colder water with ice brings out the mint a bit more than un-iced water does. Maybe it's just me but there was a difference between smoking it iced and not. But, with other tobaccos not containing mint I really haven't noticed a difference in flavor with iced water. Since I really don't smoke for clouds I really never paid attention to that aspect of icing the water. I ice occasionally but not very often. Smoke happy.
