The Doctors: Liquid Nitrogen
The Doctors showed off Liquid Nitrogen, which at a temperature of -200 to -250 Fahrenheit is colder than the Arctic. Have you wondered what that does to your body?
Cold temperatures can constrict your blood vessels, which is why ice is used to treat injuries. Dr. Travis Stork used a balloon and Liquid Nitrogen to demonstrate how blood vessels are constricted by cold temperatures.
