What I haven't seen addressed in this thread is the effect that the diameter of a straw has on cooling the drink as it goes into your mouth. It may seem menial (well, if you're reading this thread, NOTHING is too menial :wink:) but it seems that a smaller diameter straw would have the ability to cool a drink better than a larger diameter straw. I think of it like a car radiator; small tubes (thin straw) travel throught the housing (libation) and are cooled by the outside airflow (ice at top of drink.) I understand the ice is already mixed with the drink and all, but maybe the increased surface area that is touching the ice with a small diameter straw (in relation to the AMOUNT of liquid in straw that is not touching outer straw surface) will give the drink one last chilling effect before it hits your mouth. That may be total BS, but it definitely got me thinking.
