I have an all original 1975 Model lamp, I have been messing with the coil and have lost a little liquid out of it. I need to add a couple of ounces but I am not sure what I can add that wont hurt it. I was told mine has different chemicals than newer ones. Any ideas?
I have a 1975 model Lava lamp that no longer works. It lights up but the goo doesn't blob and rise like it should. It is a 1975 model 300 Carlisle. the only thing different is the spring in the bottom is broken.
