Build Your Own Lava Lamp

Manip writes "My new project: 'The difficult part about making your own liquid motion lamp is, of course, the motion. We won't go into the lamp base too much. The store-bought ones use a 40w appliance bulb in a metal housing which directs the heat to the underside of the glass container. If you're making your own base, we recommend installing a dimmer switch so that you can control your heat output.'"

Fun projects

[Pacer]

Wow, not only can you grow your own drugs, now you can make your own lava lamp.

All the fun of enduring pop-subculture at a fraction of the price. How inspiring ... how lovely ... how un-American!

Screw Lava

[Timesprout]

I want a full on Volcano Lamp

Off Topic, But....

[Tsali]

How many /.'ers actually own a lava lamp?

Good.

Now, how many of those who raised their hand are involved in a relationship with someone.

Ahhh. You in the back. Anyone else? Good.

Thanks.

Yes, but...

[OrthodonticJake]

The real question is whether or not you can make it edible. Extra points if it tastes good while heated!

Re:Off Topic, But....

[Anonymous Coward]

Make sure the guy in the back understands that a hand does not count as 'someone.'

Re:Off Topic, But....

[quizwedge]

or try this....

How many ./'ers are involved in a relationship with someone.

Ahhh. You in the back. Anyone else? Anyone at all?

No? Well, sir, do you have a lava lamp?

Random Numbers.

[wideBlueSkies]

So now I can build my own lava lamp, smoke grass, and have my very own source of Random Numbers [slashdot.org].

Cool. cough. cough. Anyone got a clip?

wbs.

Add a roll-your-own strobe light and black light, and we can open a nerd Spencer's Gifts.

I've been working on a perpetual motion machine. But it seems like its taking forever and a day.

DUCT TAPE!! This is the most important ingredient in any MacGyver creation!

Re:Screw Lava

[zephc]

I want a build your own E-Z-Bake Oven HOWTO. Maybe one that could fit in a 5.25" drive bay?

Sure, it takes 4 hours to bake a cupcake, but still. Just don't think about adding eggs unless you don't mind a little salmonella.

Re:Off Topic, But....

[Anonymous Coward]

I was involved with this one girl, but it got to be too expensive, so I outsourced to India and now save 80% on the cost of maintaining the relationship! .....sigh

Useless!

[Stephen Samuel]

If I wanted a great oozing mass bouncing around my living room and changing shape randomly, I'd invite McBride or one of his SCO PR lackeys over.

(Not enought SCO news today.. I really HAD to do something to get my fix)

Geeks on homegrown drugs making homegrown lava lamps...

Hmm... and only a couple of week on the tail of this article [slashdot.org]... ;)

Re:How would MacGyver do it?

*smacks forehead, ducttape, yea, what was I thinking.

I also think he'd use a button. Probably ground up and used as a catalyst somehow.

Lava Lamps?

News for Hippies, stuff that matters

Build your own fire hazzard

[combinatorics]

Now I can build something that:

o has no documentation about it's foundation
o is a potential fire hazzard

and pay more than what a well engineered alternative would cost.

Sounds like M$ to me.

Navier-Stokes Equations and Brunt Vaisala Frequenc

[thedogcow]

Lava lamps are a particular good example of the behavior of atmospheric and fluid dynamics.

The Navier-Stokes Equations and Brunt Vaisala frequency come to mind.

Of course this simplifies down to F = MA.

God Bless Newton.

How to tie-dye a tie... and a tutu, too!

[steveha]

First you take the tie you're going to dye and tie it. When the tie is tightly tied, you dip the tie in the tie-dye dye! Ooh! When the tie-dyed tie is dried, you take the dye you just applied and set it aside. Re-tie the tie-dyed tie, take another dye, dip the re-tied tie in this dye, too. Take it out, let it dry, untie the tie, and you've got a tie-dyed tie. And a tie's not all you can tie-dye. You can tie-dye a tutu, too! Take the tutu, tie the tutu, dip it in the dye, let it dry like the tie we dyed, now tear the tutu in two. Now you've got two tutus to tie-dye! Take the two ties you tie-dyed, and the two tutus you've torn in two and tied, and dip them in the dye!

If anyone knows where this came from, and where I can buy a CD or something with this, please let me know. (I believe I saw this performed on a TV show called Laugh Tracks or something like that, but it predates that show.)

Hopelessly inefficient...

[Goonie]

What kind of environmental vandal uses an incandescent bulb in a lava lamp? What right do you have to pollute the world by your wanton waste?

With compact flourescent bulbs, there is now absolutely no excuse to emit all that completely pointless waste heat to illuminate your lava lamp! The lamp will be cheaper to run, and the bulb will last longer too!

Just such an American thing to do...

Re:How to tie-dye a tie... and a tutu, too!

[Anonymous Coward]

where I can buy a CD or something with this

Buy CD-R blank
Record self reciting instructions in jaunty manner
Burn audio recording to CD
Congratulate self on job well-done (optional).

Or if you like, I can perform steps one through three and sell you the resulting CD for $19.95.

Re:Off Topic, But....

[Anonymous Coward]

Err, I think that hippies have a much bigger chance of having actual human relationships than other subgenres of geeks.

Of course given a geek with a lava lamp, the big question is whether the geek is a hippie-geek or a computer-geek who wants to generate random numbers...
