The bulb in my lava lamp burned out several months ago. It was an odd size, so I eventually had to order one off the internet. Unfortunately since the lava had been sitting for months, it doesn't really want to flow anymore. So I did a google search and found
a lava lamp fan website (with a forum, of course). So I've been messing with it on and off all day, trying some of the tricks mentioned to get my lava lamp working again.
There was a chunk of lava stuck at the top, and a chunk at the bottom. After messing with the temperature, I finally got all of it to melt, but now it's all floating at the top and doesn't seem to want to sink.
Maybe I should just go buy a new one. :)
