the heat transfer function depends on delta temperature and the conduction coefficient.

the freezer is fine but air is a poor conductor. I suggest you put the can in a bath of ice water. should be cold in 10 minutes.

to increase the delta temp, you can also use liquid nitrogen but use a face mask as boiling N2 can splash and cause injury.

You don't put salt in the Coke, you put it in the water that the Coke's in. Just wipe the mouth...or pour it in a glass.

No no, re-read what I wrote. I understand that you can super chill liquids to their freezing point (and beyond) using salt in the surrounding solution. What I was saying is you could actually prevent the liquid you are chilling from freezing solid if you saturate it with salt. But the issue with that would be separating the salt from the solution after you have super-chilled it and want to consume it.
