If
they do it with individual fish why not a whole aquarium?
Sort of gross I guess but would be interesting to look at and
could be very beautiful.
Indistinguishable from an aquarium with live fish and plants
except nothing moves. Guess you could leave the plants out
of a cylindrical version
and rotate the whole thing.
Do this with a whole aquarium full of fish.

Wow, ideas... my children could be so well-behaved... |

"Plastination, the latest thing in childcare ... " |

Would work well for the elderly, too. |
|
| |
m'yeah this would be an Aquariortuary. |
|
| |
I can think of a few busy corridors filled with
certain people that would make a great frozen
block or resin. Drop it into a large tank of water
and let the fish swim around them instead. [+] |
|
| |
It could be tricky to get all the fish arranged nicely at the
same time. However, there is another option. |
|
| |
Acrylamide plus bis-acrylamide are water-soluble, and can
be polymerized into a crystal-clear gel using a light-
activated catalyst. So, simply dissolve the
acrylamide/bis/catalyst in the aquarium water (about 8-10%
should do it). The fish will probably survive this for a few
minutes. Do this under red light. Then, when the fish are
all in a nice position, fire a powerful xenon flash and -
gadulka! - you have your freeze-framed aquarium. |
|
| |
1- Get the fish and plants pre cast, they have a lot
of
them on line. |
|
| |
2- Put the plastic encased plants in place in the
gravel. |
|
| |
3- Pour your first layer of resin to cover the gravel.
Let
harden. |
|
| |
4- Pour your second layer of resin to the level
where you
want your first fish to be "swimming". When it
hardens,
put your fish or fishes in place on top of that layer. |
|
| |
5- Pour the next layer of resin encasing the fish
you just
placed, then place more fishes on top
of that layer when it hardens and so on. |
|
| |
Since the resin encasing the individual fish is the
same as
the resin of the entire "resinarium", the boundary
between
the block each individual fish is encased in and the
resin
pour around it will be invisible. |
|
| |
This would allow each fish to be carefully placed in
the
position you want and eliminate the possibility
that
one non-cooperative fish might make a funny face
or
something when you kill it with the powerful xenon
flash. |
|
| |
Hope PETA never takes over, I'd probably be brought up
for crimes against the animal world for even thinking of
this. OK, all fish must die a natural death while being
sang
to
after living a long, prosperous and fulfilled life. |

ATTENTION ARTIST WITH A SENSE OF THE MACABRE:
Doesn't have to be just fish. You could get some kind of
Hieronymus Bosch style diorama of crazy things
all hanging out together. You know, fish filling up a little
car at the gas station, another flying a toy helicopter, a
squirrel bowling. |
|
| |
Eh, it's creepy enough with the dead fish. That's probably
pushing it. |
|
| |
The problem with that approach, [doc] is that there will
inevitably be a difference in refractive index between the
pre-embedded fish and plants, and the remainder of the
resin. As a result, you'll create the effect of numerous fish
and plants, each trapped in its own ice cube, hovering
strangely in an otherwise empty tank. |
|
| |
When they embed things like insects (and fish, I guess) in
resin, they pour half the resin, then wait for it to set to the
gel state. Then they put the embeddee on top, and pour on
more resin, made to exactly the same composition as the
first lot. Having identical resins, and the fact that the first
layer is not fully set before the second is added, largely
avoids the refractive index problem. Even so, if you look
sideways at an embedded insect, you will often see the
discontinuity between the two resin pours. |
|
| |
Can the insect see the discontinuity too ? |
|
| |
//Having identical resins, and the fact that the first layer is

|
| |
Thought I made it clear that would be how this was done. |
|
| |
Yes, it's clear, but there's still a visible discontinuity ... |
|
| |
Have them dipped in the first layer rather than embedded in
a cube so any discontinuity is concealed by the contours of
the object. |
|
| |
Yes, but Cubes are good ... |
|
| |
Ah - I thought you were buying in pre-embedded fish in their
own resin blocks. Apologies. |
|
| |
Just showing an example of how the fish looked in resin, no
worries. |

That being said, no matter how visible the delineation
between original casting of the specimen and the overall
casting, I think the main critiques would be about having
all these dead creatures arranged as decorations. |
|
| |
Although museums have dioramas of dead, stuffed wild
animals and nobody complains. At least a museum in San
Francisco does. Lions, tigers, elephants, all as dead as
Caesar and stuffed like pillows. Hell, they put dead flayed
humans on display. Damn it, I'm defending my dead fish
dioramas. |
|
| |
I take back everything I said about this being creepy. This
could be really cool. |
|
| |
You could really unsettle someone who had one of these, by
carefully drilling out one large and one small fish, refilling
both holes with matching resin, but embedding (in one of the
holes) a similar large fish with the tail of a small fish
protruding from its mouth. |
|
| |
Or just drilling them all out and orienting them
towards the person like they're looking at him. |
|
| |
There's a variation of this that I'm not sure is worth
posting. |
|
| |
Have the specimens dipped in plastic, carefully
balanced with measured boyancy so they float
upright at a particular level, then circulate them
around the tank with a cyclonic water path. |
|
| |
You'd
have to somehow streamline the rear of the
fish so it was less resistant to the water flow than
the front lest they "swim" backwards but
presumably if you had the time to do something
like this you could figure something out. Open the
gills up maybe. |
|
| |
By the way, if somebody wanted to put a little
work into it and have these now available robot
fish be able to recharge somehow, perhaps going
into their little castles at night, we could be
looking at a very small revolution, that of robots
replacing fish in a few aquariums. |
|
| |
// robots replacing fish // |
|
| |
"These aren't the Dorys you're looking for ..." |
|
| |
//robots replacing fish in a few aquariums// I'd hake to sea
that happen. But clearly you dance to the tuna of a different
drummer. |

| |
That's because he needs his herring aid to hear the music. |
|
| |
It would be pleasing to have (but probably quite difficult to implement) a half-open treasure chest, with a stream of frozen bubbles rising up through the resin. |
|
| |
Cast the treasure chest, with air supply, into the resin. Once fully polymerized, drill down to it, then polish the resulting bore to a smooth finsh. Fill it with a liquid with a suitable refractive index, then turn on the air. Et viola ! Bubbles ... |
|
| |
Or cast a preformed transparent tube into the resin for the full depth. |
|
| |
// Then, when the fish are all in a nice position, fire a powerful xenon

|
| |
I'm not sure whether this would work for [Maxwell's] acrylamide-bis-
acrylamide mix; could you wait for just one fish to be in a nice
position and only shoot xenon through that specific column of
water? |
|
| |
Repeating this for all other fish and finally shooting one last burst of
xenon all over the aquarium would give you more individual freedom
over the fish's positions. |
|
| |
As a side note; this is my first annotation, and I worry that I'm doing
this all wrong. |
|
| |
You're polite, thoughtful and intelligent, so yea, you're
doing it all wrong. |
|
| |
Kidding, you're fine. Welcome to the club. |

// I worry that I'm doing this all wrong. // |
|
| |
Relax; if you do, there's no shortage of people to explain in excruciating detail exactly how and why you're wrong, correct your spelling and grammar, criticize your use of language, point out any technical errors or omissions, cast aspersions on your ancestry, education and personal habits, and generally insult and demean you. |
|
| |
It's like a fraternity initiation ritual, except it never stops. |
|
| |
// only shoot xenon through that specific column of water? // |
|
| |
The problem there is that the column created probably isn't going to be securely anchored to anything, and may also undergo a change in density. Any small movement of the remaining liquid, even thermal convection, will then be enough to displace it from the chosen position, spoiling the effect. |
|
| |
Solidifying the whole mass of material simultaneously does guarantee fixing the relative positions of the objects within the resultant block. |
