People apparently tend to judge others, when they meet, as literally warm or cold in character dependent upon whether the one doing the judging is holding a hot or cold drink at the time of the introduction.
What then happens to social interaction in warm parts of the world where a glass of iced tea could cause a breakdown in relations? Today’s invention is a way to give someone a cold drink which is held in a warm cup and thus avoid being emotionally labeled inaccurately.
The cup would have insulation between the cold interior and the warm exterior. It would be possible to arrange for a reversible chemical reaction within the the outer layer which would extract heat from the inside of the cup (using some of the technology within self-chilling/heating cans).
