Why do some objects feel colder when in reality they are the same temperature?
In this video pedestrians in a park are asked why a hard drive and a book sitting at the same temperature have a different temperature feel to them. The hard drive feels colder than the book. He then takes an aluminum plate and a plastic plate to see which plate melts ice quickly. Even though the aluminum plate feels colder, it melts the ice quickly. This is a good experiment to try with your students.
