You may be noticed that the foods in your refrigerator have been rotten after a few days you came back to the home. This happens because of the power outage when you are not at the home. 

How do you know whether there was a power outage or not? Today, we inform you a simple but successful method to know that. 

First, put a glass of water in the fridge until it becomes frozen. Then place a coin top of the glass. 

If the coin is in the bottom of the glass, it means that you had a power outage, and you should throw out the defrosted foods.

However, if the coin is still in the top of the glass or middle in the glass, it means that the food is good to eat.
