This ferrofluid fountain would
possibly be the most
surreal fountain ever because the
possibilities are endless.
Quick run down: Ferrofluid is a fluid
that responds to magnetic fields.
So thanks to linear engines you can
have a fluid that runs up hill or
follows a complex track
on a wall.
An electromagnet suspended from
the ceiling would only be able to hold
so much ferrofluid before it would
come dripping down.
Powerful magnets would crystalize
the fluid into jagged shapes
dependent on the magnetic field.
Considering that speakers use
magnets to produce sound you can
see how this fluid could change with
music provided.
What fountain is complete with out
an arc? Powerful magnets properly
positioned could make such an arc
curve around other objects.
Plus, if let's say the ferrofluid was oil
based and there was a pool of water,
linear engines could move the
ferrofluid in a serpentine route in,
out and all around the water.

This sounds utterly fascinating! |
|
| |
Would ceiling located electromagnets be capable of
creating stalactite shapes of ferrofluid or would the
suspended ferrofluid be topographically homogenous? Or,
do the ceiling electromagnets come into play only for
distorting the surface of the ferrofluid as it remains more
or less pooled on the lower horizontal surface? |
|
| |
silly questions - what colour is this stuff? is it thick like custard or engine oil? |
|
| |
Gets my 'YES YES YES!' vote for the week. Counting down until someone figures out a ferrofluid clock... <later edit> apparently I'll be counting backwards, which is somehow appropriate. |
|
| |
I'd like one which spelled out my name in the most complex was possible. Egocentric me, eh? + |
|
| |
Sorry [sartep] but I have to vote against this. Using ferrofluids in a fountain seems like an obvious extension of the technology to me and ANY ferrofluid fountain is likely to be surreal. |
|
| |
(New Edit) You should have posted
the idea so we could all see it.
Some of the best things turn out
to be obvious extensions of
technology. Like the 100th year
anniversary of putting an engine
on a box glider. That PDF is still
quite different than what I
described, thus not as obvious
first described. |

Po, for a while I was considering
something like a magnetic jello
cube fountain with just enough
plastics to be a cube when not in
motion and then immersing that in
small ammonts of water. |
|
| |
I worry about you, sartep! and lay off his phoenixness... :) |
|
| |
Ok, sorry. I did a search for
ferrofluid fountains on halfbakery
too and didn't see your anno
phoenix. It's one of those ideas
that I had for a long time and did a
pretty extensive search on the web
because I thought surely someone
built this by now. I'm still keeping
it. |
|
| |
a fountain in which water flow takes on new shape and/or direction according to music. no idea of its inner workings, but it sounds cool as hell. |
|
| |
sartep, thats alright, he's big enough to fight his own corner! |
|
| |
Talking of surreal fountains, I saw
a lovely fountain at the Miro
museum in Barcelona. I looked at it
for ages, thinking there was
something odd about it, before I
realised the fluid being used was
mercury. |
|
| |
Hell, I'm so big I don't even _fit_ in the corner. |
|
| |
Wear pointy shoes. Helpful if you need to kill cockroaches who are cornered. |

Are you The People's Phoenix? |

I saw a photo montage of a ferrofluid fountain in Wired once. Can't find it now, but it was essentially this. |
|
| |
Sounds gorgeous... It's faaaaaar better than a Lava Lamp! The only drawback is not being able to toss in a penny and make a wish. |
|
| |
Crap, I was just going to post Ferrofluid Falls but it looks like it's a couple of years obsolete. (+) |
|
| |
+ let's read some good ideas here. |
|
| |
I am thinking about setting the ferrofluid alight. I am wondering about ferroflame. I think the smoke should be magnetic too although only in the way crappy iron dust is magnetic. Unless the iron oxidizes in the heat. In which case there would only be the beauty of a flaming, smoking pool of oil. |

Hi, any word on this? Is it too expensive to produce - is that why no one's done it? Or maybe too messy? |
