a few days ago i made my first bong using one of those vitamin water bottles, i made a hole near the bottom, then cut part of a straw and stuck it through the hole, added water, and i put a joint at the end of the straw, lit it up, and surprisingly it worked pretty well
it was actually a pretty good first time bong experience

but, the next day, when me and my friend tried to use it, we ended up just smoking the jay alone instead cuz we couldnt get it to fit in the stem, plus a little bit of water sometimes leaked out the hole, and we were kind of in a hurry because we were in a semi-risky spot.

here is a pic of it:


(yes you actually have to hold the stem up lol)
(thumb is over the carb, which i made just now and wasnt there before)

any ideas on how to improve it, and make it more comfortable?
i would also like to keep it portable
