MODERATORS
There is a machine that specifically cools drinks (cans) in seconds. It rolls the can in ice water until it's cold.
why the roll?
Heat transfer by convection
Technically not by convection because that is the movement of fluid to transfer heat in and out of something, like air conditioning. The bath is not a moving fluid it is a simple constant temperature. The spinning moves the fluid inside the can so more of it touches the aluminum wall, which is being cooled by conduction with the ice bath.
