I've got a wonderful acrylic bong with a lot of sentimental value (filth didn't find it in either of two busts!) but it leaks like crazy right out the bottom of it. It's staining my crappy wooden shelves & making them reek of bong water (don't really care) and it gets everybody who uses it wet and stinky. It's way better than any of my other bongs though (even the glass one... the shape & size of this one is just right) and I don't wanna go buy a new one if I can avoid it. The bong only has a cap on the bottom, not a proper bottom, and you can see there isn't any kind of sealant... I tried hot glue, which worked for one day but then it started leaking again... pulled that off and tried gorilla glue and that didn't work at all. Thought maybe somebody else had had this problem... any ideas?
