I've decided to tentatively let my Colossus Lava Lamp go. I haven't got the patience to work with it to get it flowing properly and my house is never consistently warm enough for it to run properly.
It is pink wax and clear liquid. It comes with 2 x 200w bulbs. The bass has been altered to accommodate the bulbs.
For sale or trade. I'd be very interested in trade for a wave machine. Possibly fibre optics or maybe an Opal Fluidium but feel free to make any offers.
I'm based in North Wales. Not far from Chester.
