[In his column,](http://www.straightdope.com/classics/a2_359.html), Cecil writes:  
_“As Cecil’s more venerable readers know, the lava lamp was one of the three indispensable components of the properly furnished 60s apartment, the other two being a black-light poster and a waterbed.”_  
Ahem. Bean bag chairs? Beaded curtains? I can only imagine that the life of the sage was not always so well paid, and The Master’s furnishing budget was somewhat limited…

I don’t know how Cecil can wax so nostalgic over lava lamps, and speak so disparagingly of [The Prisoner](http://www.straightdope.com/classics/a2_022c.html). I can’t look at a lava lamp without thinking of that old series.

And what of the long chains of beer tabs hooked together and draped over the corners of the cinderblock-and-board entertainment center?  
The large cable spool for a coffee table?

Luxury! Ours were made of milk crates; indeed one of my friends had an entire flat furnished with them - bed, wardrobe, chairs, tables, the lot.

Ummmmm…

I sleep on a waterbed.  
I have several blacklights, including a 4’ fixture that is on 24-7 (and has been for more than 20 years now).  
I still have one bookshelf that is cinder blocks and 1x12 planks.  
I have a glow-in-the-dark beaded curtain in my closet doorway.

If this is a problem for someof y’all, come on over. We can have a smoke and talk about it… man. ;j

Why did the question of Lava Lamps have to be SO CONFUSNG? It’s pretty simple… You have a substance that is always liquid(Always, according to OUR scientists, of course…) and you throw a substance that is liquid(and lighter) for a VERY short period of time. Al yu have to do is HEAT this substance… To make sure that heat is retained in the bottom of the ‘Lava tube’, how many people REALLY pay attention to the coil at the bottom?

I was always big on black lights. Thought that they were so cool. But I have read that they contribute to cataracts, and since my Mom had them, Grandma had them, Dad had them and a few other relatives, I figure I had better be cautious.

Hmmm, I never heard that before. I’ll keep it in mind, tho. If it’s something you read recently can you help me with a link? I enjoy my sight tremendously, as without it I could not read or enjoy pretty women as much.

I forgot to mention above that I also own strobes, a mirror ball that hangs in my bedroom (chicks dig it), and (YES!) a lava lamp.

Wouldn’t it be cool if lava lamps were filled with real magma?

The waterbed was usually bought with your tax refund after you got your first serious paying job.

Ummm…wouldn’t that just mean that there was a lump of brown rock at the bottom of the lamp?

Though the word may have several meanings depending on the context, the context of this thread makes it pretty clear what [definition](http://dictionary.reference.com/search?q=magma)\* I was referencing. BTW, none of the definitions fit your post. 😛

\*think about it: lava, molten rock, magma…

But the fluid in a Lava Lamp is water. And _heated_ lava/magma would boil it to steam. Or cool the lava, to a brown lump of rock.

You’re forgetting the force field and the phased pulse emitters! That keeps the molten rock safely enclosed _and_ melted, monkey boy

Sheesh, it’s like I gotta spell everything out for you humans. Oh, how I long for my old home in fluidic space.

I have (pause to mentally picture my apartment and count them, since I’m presently away on vacation) 12 bookshelves that are constructed with cinder blocks and planks.

Bosda Di’Chi of Tricor/NoClueBoy

Just for clarity;

Magma is molten rock beneath the planet surface  
Lava is molten rock above the planet surface  
Cooling of magma/lava results in the formation of primarily granite, basalt, or any of a number of variations (gabbro, rhyolite, scoria, pumice, obsidian, diorite), not a “lump of brown rock”.

So a lava lamp couldn’t be filled with magma unless it was in your basement.
