Bubbles

The lava was stuck at the top. Probably a symptom of the lamp being shifted around during the move.

After much shoogling (technical term) and convoluted repositioning I seemed to have managed to free up enough wax to get a bit of action going.

Any other ideas would be most welcome as I
love this wee lava lamp and don't want it resigned to the big retro scrap heap in the sky?
