Forecasters in South Dakota used two bananas to illustrate the importance of wrapping up warm as much of the Midwest and Northeast battled extreme cold on January 30.
In South Dakota, wind chills were expected to bring lows of between 10 and 20oF below zero overnight (-23 to –30oC) between January 30 and January 31.
This video shows a meteorologist from the National Weather Service in Sioux Falls leave two bananas in the cold for several minutes. One banana has been peeled and the other not. At the end of the three-minute period, the peeled bananas is frozen solid, whereas the other banana is still mushy. The meteorologist urges people to wrap up warm in the cold by using gloves, hats and scarves.
