# Mercedes crystal

Large
 (+27, -1) [vote for, against]

Most molecules can be crystallized. Mineral crystals are abundant, of course. Complex biological molecules (proteins, nucleic acids and others) can also be persuaded to crystallize, though it is often tricky. The results are frequently beautiful, with a geometry which, although often variable in dimensions, is based on a consistent set of angles - rather like piece of music in a certain key.

Cars do not usually crystallize, partly because they are not soluble. In their normal situation, a mass of cars will simply slump into a pile wrought by gravity. Numbers are also a problem - a decent crystal requires at least a few million identical subunits.

Here is the answer. First, we take about 10^6 or 10^7 identical cars. (OK, this is not strictly an answer, more of a requirement. Bear with me.) Next, we need to get them into solution. This could, possibly, be done by preparing some sort of mercury amalgam which would have the same density as the cars, and in which they would float. However, this would obscure your view. Moreover, each car would tend to float in an orientation dictated by gravity (eg, engine-end down), which is not what we want.

So, we need to put the cars into a zero- gravity environment. Space, for example.

In zero-G, the cars will interact primarily by gravitational attraction, mimicking the van der Waaals forces between molecules in solution. The forces will be extremely weak, of course.

In time, a few cars will gently collide and, very slowly, will snuggle together in the most energetically-favourable configuration. Gradually, other cars will accrete into these, each one again jiggling and snuggling into the optimal arrangement. Over a number of years, all the cars will gradually precipitate into a single, perfect crystal of cars.

Of course, normal crystals contain flaws such as dislocations, which often help the crystal to grow faster, by providing "cosy corners" into which new molecules can fit. Doubtless similar phenomena would arise in an automobile crystal.

Remember, if you're not part of the solution, you're part of the precipitate.

 The problem with mercury is that it forms an amalgam with many metals. You need a solvent which has a similar density as cars, retains a resonable viscosity in the low temperatures present in space, and has a low vapour pressure (mercury has quite a high vapour pressure).

 Since you propose the experiment (activity ? art ?) be performed on a macroscopic scale, the "solvent" does not in fact have to be a liquid. It can be any material with a suitable "viscosity" and a particle size which is small compared to the cars; although whether this would mean that you would then have a suspension, emulsion or colloid is open to further debate.

 The use of large quantitites of glass beads or marbles suggests itself. Any other suggestions ?

PS Please don't park your edifice too near our Cube, we have only pulled up to ask directions and are not good at reversing out of small spaces.
 — 8th of 7, Dec 15 2007

I wonder if such a crystal could be cut into a shape that accented the refractive index, and then mounted on Saturn's rings.
 — Ling, Dec 15 2007

 //The use of large quantitites of glass beads or marbles suggests itself. Any other suggestions ? // The problem will be one of friction and gravity - a large container of glass beads, populated with Mercedes, will remain in the same state for an exceedingly long time. Hence my suggestion to do this in space.

 [Lurch] - Hummer doping may well introduce novel properties. Moreover, it may be possible to co-crystallize Mercedes with some smaller vehicle, such as SmartCars, in equimolar amount. Using suitably long- wavelength radiation, one ought to be able to solve the structure of the co- crystal by diffraction, and therefore discover the structure of the Mercedes/ SmartCar complex.

[Ling] nice idea. I'm not sure if the binding energy of the crystal would be enough to overcome tidal forces from Saturn's moons, however.

//Any other suggestions ? // Road cones?
 — lurch, Dec 15 2007

 Road cones will hav peculiar packing characteristics, high "viscosity", and their size and suface area are significant compared to the "solute"........

 // remain in the same state for an exceedingly long time //

 I do not dispute this, just a first thought. A free-fall environment will help. Maybe a PTFE coating on the spheres, or molybdenum disulphide ?

<later> The idea of co-crystalising is intriguing; it would be appropriate to consider the position of Mercedes in the electroautomotive series, and from this compile a list of possible reactants thet will readily form stable covalent bonds.
 — 8th of 7, Dec 15 2007

I have seen a SmartCar covalently bond with a Mercedes, but this was in a controlled experiment using accelerated particles. We're not necessarily looking for covalent bonds, which would in any case distort the Merc. Non-covalent interactions are likely to be more common.
 — MaxwellBuchanan, Dec 15 2007

 //pleasing patterns, based upon magnetic field lines.// Yes, an interesting idea, but not what I had in mind. You see, if you magnetized the cars, you would effectively predefine their aggregation pattern, by defining the locations of the north and south pole of each car. It's true, of course, that electrostatic interactions guide the formation of a protein crystal (in a way not too dissimilar to magnetism), but I don't like the idea of imposing an arbitrarily-chosen pattern in this way. I'd sooner just rely on gravity, which is sort of a vague proxy for van der Waaals forces.

 //Personally, I'd go with the V Dub "dak-daks" for their uniform shape.// I'm not sure what a "dak-dak" is, I'm afraid. If, by "uniform", you mean that each of them is identical to the others, then this is of course essential for good crystal packing, but I'd expect any well- built car to have a consistent shape. If by "uniform" you mean simple or symmetrical, then I'd oppose this. Protein molecules are anything but simple or symmetric, but the miracle of crystal growth means that they nevertheless find the optimal regular packing geometry.

If crystallogrophers are half as smart as they are supposed to be, they actually ought to be able to predict the packing arrangement from the shape of the car.

 // distort the Merc //

Only the electron shells, and even then only in a probabalistic sense ....

 The Merc/SmartCar amalgam that I saw was a probabilistic write-off.

Let gravity suffice.

OK, consider this. Water molecules can form a crystal, and can be imagined as a large ball on top with two smaller balls below. NH3 would be a large ball on top of three smaller balls, while a large ball with four smaller balls underneath forms a Pivo.
 — lurch, Dec 16 2007

 // a large ball with four smaller balls underneath forms a Pivo //

Ahhh .... combined with their enthusiasm for Pachinko, this explains why almost all Japanese cars are a pile of balls .....
 — 8th of 7, Dec 16 2007

//Water molecules can form a crystal, and can be imagined as a large ball on top with two smaller balls below.....// Quite so. But the crystal form is very difficult to predict from the molecular structure alone, especially in the case of complex molecules such as proteins or saloons.

Merely a flaw, but that's how you know it's natural and not synthetic.

If the Mercedes yields the good crystal, then Mercury is the cheap zirconic knockoff.

Actually, the process of crystallization is quite effective at excluding impurities. All dirt, debris, dead ducks, dust, dental floss, detritus, and dung should be excluded and will appear on the surface of the crystal, whence it may be simply wiped away.
