Leaving a coin in the freezer might seem peculiar, but there’s a practical reason behind it that can benefit you before heading out. It’s a simple trick that can provide peace of mind.

The concept involves placing a coin on a frozen surface inside the freezer, like a tray. When you return home, check the freezer. If the coin is still in its original spot, it indicates that the power remained uninterrupted during your absence, assuring that your frozen goods stayed preserved.

This hack is especially useful during power outages or if you’re concerned about the integrity of your frozen items. By implementing this easy trick, you can have added confidence that your freezer contents remained safe while you were away.
