Heading off on vacation and worried about a power outage spoiling your food? There’s a simple yet ingenious solution to ensure your food remains safe. This hack, which uses just a cup of water and a coin, can alert you to any power failures that might have occurred in your absence.
Here’s what you need to do: Fill a cup with water and freeze it. Once the water is completely frozen, place a coin on top of the ice. When you return from your trip, check the position of the coin.
If it’s still on top, your food is likely safe – the power stayed on. However, if the coin has sunk to the bottom of the cup, it’s a sign that the power was off long enough for the ice to melt, indicating your refrigerated items might have spoiled.
This trick is not only useful for vacations but also in emergency situations like evacuations due to natural disasters. It’s a straightforward way to avoid the risk of consuming spoiled food, keeping you and your family safe. This method provides peace of mind, letting you know the status of your refrigerator during your absence.
