never smoke out of copper of any sort,when burned copper releases poisonous vapors,a black film(for lack of a better word) covers area that the flame is applied to,this is acctualy vaporized copper,that means when useing copper your inhaleing copper,nasty,and gives a bad taste....and will kill you...if you like makeing homemade pipes,bongs,whatever(i do,but most of mine are never used)i'd get a hot glue gun,and some sockets and let your mind take over from there.i make a 29 1/2 inch bong from a gatoraid bottle,a lot of hot glue,two paper towel rolls,part of an arrow(most are 10mm in diamiter,so they make the perfect stem from almost any bong),and a socket.it hits great and always gets comments when freinds come over,because of the way it looks i named it hermun munchster(it acctualy looks pretty good but the name came to me when i was mid-hit and i had to use it )but i just got two glass pipes that i love with all my heart so i havent used him in a while...i think when i get some i'm gonna hit ol' hermun
