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. |
