I've never seen a lava lamp with liquid more crystal clear than this one, there's two or three bubbles in the glass though. It's a 2002 globe, made in the US.
Just as a note, the globe likes to be warm. (That's why it's in my blue swirl base & cap)
It's an original, unmodified globe, #18.
I may consider selling it but really I would like a "good" teal globe.
(Just as a note, I'm from Pennsylvania so it would be easiest to keep in within the US.)
