Though lava lamps were more popular a few decades ago, you can still find them in most stores. I donít think they ever really went away, but they may never be as popular as they were back then. I had one in college, but that was only because I was bad with money and I didnít know any better. It was, after all, pretty and blue. How was I supposed to resist that? Today, I could easily resist, but back then, well, I just had to have a lava lamp of my own. I guess maybe it was curiosity more than anything.
I bought the lava lamp with the intention of going home and watching it for a few hours. After those few hours were up, I was going to take the lava lamp apart to find out just what exactly was inside and how it worked. Now I know today you can just find that information online, but when I was in college, the Internet was a few years away from being available to me. I took the top off of the lava lamp and discovered it was contained in a glass container with a lid. The lid looked like a sealed lid from an old soda bottle, and this alone stopped me from totally taking it apart.
I was worried if there was a seal, and I broke it, that my lava lamp would never work again. I guess after watching it for a few hours before taking it apart made me like it more than I thought I would. My roommate and I enjoyed the magic of my lava lamp for a long time, but we still wondered how it worked. As far as I could tell, the floating stuff inside the lava lamp was some sort of wax. I could be wrong, and honestly, I still havenít looked it up to find out for sure. I was assured that the water was not just any water, but I am not sure about that. I do know that they wax-like material as heated by a bulb in the bottom of the lava lamp, and that heating caused it to rise. Perhaps the cooler water at the top cooled it off so it sank again, but I really donít know. What I do know is that when a lava lamp has been on for too long, the wax just hangs there in tiny blobs that bop around a bit. Perhaps I should dig out my old lamp and take it apart once and for all, or perhaps, Iíll just save myself the trouble and the mess, and go look it up.
