Basic simple and dumb experiment -- blow on your hand, hard and with a
narrow lip opening, or slow and with a wider opening -- it _feels_
colder and warmer, respectively. But that would be wind chill rather
than a really significant temperature difference, I suspect. :-)

I suppose that blowing-on-the-hand exercise might be useful to give a
student a sense of what different kinds of breath they can use.
Alternatively it might be a good way of getting the head out of the way
of what's physically happening...
