So the same thing happened to me... as I was emptying out the dirty water, the base of my bong tapped the porcelain of my bath tub and got a huge crack. I let it dry and stupidly used it a couple more times before the base broke into a couple pieces.

I used aquarium glue to seal it back together and it seems to have worked so far, but I need to let the glue dry for 24 more hours before I'm even gonna think about using it again.

Couple questions though... would putting an extra seal of JB Weld on the outside of the bong over the aquarium glue be a bad idea? I mean, it seems like extra reinforcement, but I don't want to end up ruining the seal.

Not to mention, after using the aquarium glue, did it have a different taste afterwards?
