It's 2am on exam week. Forgive me.

Often, when you wish to enjoy such a luxurious pleasure as a frosty carbonated beverage, and otherwise have no place to put it, why not make a can with a built in coaster?

Now, you ask, what would the coaster have to be composed of to be cost efficent? It doesn't have to be terribly complex or resusable, just provide ample insulation to prevent condensation from coming in contact with the drinking surface.

Is this possible? It seems that the condensation would come from the can being chilled (before use). So wouldn't the whole can cause condensation? Even the coaster section. Nice idea though.

Environmentally disturbing. Why go there? [-]

Something else... if the "coaster" were chilled along with the can, it would sweat as well on the outside for sure... what [swamilad] said.

//So wouldn't the whole can cause condensation? Even the coaster section.////if the "coaster" were chilled along with the can, it would sweat as well on the outside for sure//Intuitively, this seemed wrong, and a simple experiment with several types of cardboard and a can from the freezer showed that no noticeable condensation formed on the “coaster” surfaces, probably because it has a much lower rate of heat absorption.

The coaster cardboard would 'sweat' much less because A) it absorbes the moisture, B) is is much less conductive for heat/cold so the colder insides are insulated from the moist outside.
