Yet another hookah problem
Ok, so this problem doesn't cause any real issues with smoking, it's more for convenience. I have a stainless stem that comes in (I think) 4 pieces. These pieces have slowly started locking together, one set at a time, until today, it was no big deal because I had two separate pieces, so no big deal, but today I bring it out, and I can separate the two pieces. They are all stuck together (it's a screw connection). I can no longer unscrew them. Any one ever have this happen to them? and How do I get them unstuck?
