Before you leave for vacation, put a coin in your freezer; here's the reason

A simple coin hack can reveal if your freezer lost power while you were away. Pour water into a cup and freeze it completely before placing a coin on top. If the coin sinks, it indicates ice melted and refroze due to temperature fluctuations. This method helps assess food safety after unexpected power interruptions. Always inspect food for other spoilage signs after a potential thaw.
