Ive had this idea of having a removable bowl on a homemade waterbottle bong, and came up with the idea that i can flip a larger socket ( bowl ) upside down, and put it over the small socket ( steam ) And you pack the big socket in the little hole on the other side This thing is a pretty nice little homemade ( also tried to find a metal bowl and stem )
You can smoke your bud however you want but you prob won't find much appreciation here for plastic/metal. Not hating, that's just how these threads usually go.
