i used to make a lotta ghetto shit like that, because i couldnt afford a good piece, not because i was trying to be sneaky. i was just broke as fuck! i made a lotta shit, like i used altoids tin pipes, i mad fat disposable bongs, metal pen tube chillums, cups, thimbles, salt shaker caps, almost everything.
and the easiest way that doesnt fuck with your lungs will ALWAYS be the apple pipe
