Cold Hands, Warm Science

This morning I have cold hands.  How very fitting that the weather has turned very fall like on the eve of the first day of fall.  I am sure by the time my summer clothes are just about buried beneath sweaters and jeans it will warm up again but in the meantime I am rubbing my hands together!  And as I am doing this I am thinking about how cool this little scientific principle is.

It is why you can make fire by rubbing two sticks together.  Pretty cool right?!

Ways to Warm Your Hands

  • You can insulate your hands in mittens or pockets which works by reducing heat loss.
  • Another way you can warm you hands is by raising your overall body temperature by putting on a sweater or exercising.
  • You can hold a warm drink or sit on your hands which transfers heat through conduction or direct contact.
  • If you hold you hands over a register, the warm air blowing would be heating your hands through convection.
  • And if you hold your hands over a radiator you would be heating your hands through, you guessed it radiations, which is the heat being transferred from one molecule to the next.

  1. I am partial to wearing gloves to keep my hands cozy and warm. I like the idea of just carrying around a hot mug of something delicious everywhere, though. Wouldn’t it be cool if we could start a fire by rubbing our hands together?
