it's green!
I can't see the green one on the flow-of-lava page.
But yes, it is like the earlier ones with the non-metallic lava.
It's flowing quicker now, but am getting increasing small blobs, where a large blob has come away, there is a little weeny blob which was created in the pull between the main mass and new blob, you know what I mean.
But the liquid is denser, so they are not settling at all.
it certainly is different to my other lamps. It is growing on me now! (slowly)
i'd love a silver one like as you mentioned, I've seen them and I love how the lava looks like mercury which is just too cool.
Ant, do your glitterballs have a coil at the bottom? mine has what looks like a plastic ring, which is alot smaller than the usual coil size, that just threw me a bit!
