Science!

I left a 6-pack of 24oz Diet Dr. Pepper bottles in the car overnight, and today saw that two of them had frozen into solid slush. The two were at opposite corners of the 6-pack, suggesting it wasn't simply a case of those being closest to the heat sink. My current hypothesis is that those two have slightly lower concentrations of carbonation or other stuff, and so had a slightly higher freeze point than the other four...and the temperature in my car was JUST on the line there.

Could also be a micro-climate thing - if there's vents nearer to the two corners perhaps. It's all about dragging out that last calorie and then triggering the cascade event that starts the crystallization.

Blast it...once again physics and chemistry return to torment me before the appointed hour.

Which, by the way, is January 7th, when my 'Historical Perspectives of Physics' grad course starts.

I actually did a comic based on Dr. Pepper, which got a lot of rants going, despite the fact that it was A JOKE! I actually have nothing against either, though I am one of those people who can't tell diet and regular sodas (or Coke and Pepsi for that matter) apart.

Well, there's your problem...Prime and Unicron were drinking fountain diet. That has saccharine, which tastes sickly sweet and quite horrid to me (and to something like 1/4 of the population in general, IIRC).
