Have you ever come home to find your digital alarm acting strange? It’s easy to brush it off as a simple power cut. But do you really know how long it lasted?
It could have been a minute, an hour, or even longer. And that’s where the danger lies. If the power was out for hours, your food might have thawed and refrozen without you noticing. This process can cause harmful bacteria, like salmonella, to grow, turning your food into a health hazard.
But don’t worry! In this article, we’ll show you a simple trick to find out how long the power was out. Here’s what you need: a cup, a coin and water.
First, fill the cup with water and let it freeze. Once the water has turned to ice, place the coin on top. When you return home, check the coin. If it’s still on top, you’re in the clear. But if the coin has sunk, it means the power was out long enough for the ice to melt and refreeze. In that case, it’s best not to eat the food.
