I just recently bought a new acrylic bong, and while it hits like a champ, I've noticed that it begins leaking after a long session, or even just during regular use. I took the base off, and found that it was the bottom cap that seems to be causing the problem. It's not very air tight, and there are no sealants around it.

I was wondering if anyone had any suggestions as to a permanent fix. I thought about melting a candle around the base to seal it, but I wasn't quite sure if that would really do the job.

It was only a $30 bong, but I'm a poor high school student, so I just don't have the funds for a nicer glass one. Any help is greatly appreciated. Thanks.
