I just sat with a cup of tea, and started wondering about this. If the cup just sits there, the tea will cool slowly. Will it cool faster if I repeatedly clench and let go of the cup? The difference between the cup surface temp and the surrounding air is higher than than between the cup and my hand, but then again I sense that the heat will have an easier time transfering to my hand than to the air...and so I sit here wondering :) What do you think?
