A Christmas Story is an iconic Christmas movie, so today I decided to discuss the physics of one of its well known scenes. Ralphie's friend Flick is triple dog dared to stick his tongue to the pole by the kids in the school yard. Unfortunately, when he sticks his tongue to the pole, it gets stuck and the fire department must come to save him. The reason his tongue gets stuck is because the metal pole is a great conductor of heat. The thermal energy from your body is transferred into the pole faster than your body can replenish the loss of heat. As a result, your saliva, which is made up of 99% water, freezes due to the lack of heat on your tongue.
