gravity bongs for sure. Using an Ocean spray jug with a larger mouth for a phatty shotgun and my new favorite toy, the BC Chillum which I bought off the net (
www.bucketchillum). I don't need to handmake the bowl piece which was always the hardest part and it fits all the jug sizes outside of the Alhambra 5-gallon. Definitely use a clear bottle though so you can see the quality of smoke fill up.
Had to smoke out of an apple bong once out of necessity when a generous couple gave me left over weed they couldn't take with them on the plane. Happy to have smoked successfully, pain in the ass to make, but I was staying in a hotel with my parents so beggers can't be choosers.
