well the best thing i made wasnt really a bong, or pipe. it was a pale. twas the mightiest pale ever, and still is especially for its size. it was and is, THEE bubbler. but its a metal slide for this bong we had, so we decided to put it to use and we stuck it in a pale, and i dunno what happened but it brews dark yellow smoke every time, one hit and youll feel yourself going from sober to stoned.
