January Experiment – Winter true or false

Monday, January 17th, 2011

In many parts of North America winter is the time of frezzing temperatures, snow, sleet and freezing rain. But is it true or false that if you place your tongue against a frozen metal pole on a day of less than 32 degrees your tongue will stick to the pole?

This is true! Why? Because the moisture on your tongue in the freezing weather creates in a small bond of ice connecting your tongue to the metal pole. The solution is to pour warm water between the tongue and the pole thus melting the ice and freeing your tongue.

You can achieve the same science with no pain by using a popsicle. The slight few seconds of tug between you tongue and the popsicle demonstrates how the ice bond forms.
