Understanding Cold Feet and Fear

The video tutorial 'Duck Quack Stone Echo' explores the science behind the expression 'getting cold feet'. It explains how fear triggers the body's fight or flight response, reducing blood flow to extremities and causing feet to get colder. The show sets up an experiment with a premed student, Maxa, using a thermographic camera to test this theory.
