Why Metal Feels Colder Than Wood at the Same Temperature

Why does metal feel colder than wood when a thermometer shows both sitting at exactly the same room temperature? The answer is that your skin was never measuring temperature in the first place. You will learn that the nerves in your skin report how fast heat flows, how free electrons let metal pull heat away while wood and its trapped air hold it at the surface, and why the same rule makes hot metal burn where hot wood does not. The video also covers why saunas are built from wood, why tile feels colder than carpet, why water chills you faster than air, and why good electrical conductors also conduct heat well.
