A useful hurricane preparedness tip posted on Facebook in 2016 is making a resurgence as the east coast, North Carolina in particular, braces for Hurricane Florence.
Originally intended for Hurricane Matthew, Sheila Pulanco Russell of Lumberton, North Carolina, posted the advice in October 2016 and it has racked up more than 400,000 shares.
The tip is simple but effective: If you have to evacuate your home, stick a glass filled with water in your freezer. Once the water is completely frozen, place a quarter on top of it. This way, if your home loses power during the hurricane, when you return home you'll be able to gauge whether or not the food in your refrigerator is still good.
As Sheila explained:
If the quarter has fallen to the bottom of the cup that means all the food defrosted and you should throw it out. But if the quarter is either on the top or in the middle of the cup then your food may still be ok.
