Topic: Red Faced

The past few months I've been subbing in a woodwind quintet that performs educational concerts at elementary schools. A few times I've been asked why my face turns red while I'm playing bassoon. I've often wondered about this myself and would like to give the children a scientific answer. Anyone out there in cyberspace know why our faces turn red and what's going on in our bodies?
