@Kerm. thanks man, yeah I was having fun within 5 minutes of opening the box!......who the hell smokes oil through a gravity bong!?
Kerm ive no idea about all the terminology of the bong yet, but i think that's just called the down stem and yes it reduces the hole size for the nail attachment..but dont quote me lol
time to heat that nail again, the qwiso is going quickly.
