When you're heading out for an extended period, there are several household tasks to take care of, such as watering plants, emptying the mailbox, and perhaps even implementing some security measures.
However, one area that many people likely overlook is the freezer.
If the power goes out while you're away, the food stored in your freezer could spoil.
You might notice that various appliances are blinking, indicating a power outage, but you have no way of knowing whether the food has completely thawed and become unsafe to eat.
A clever trick shared online by Facebook user Sheila Pulanco Russell offers a simple solution: all you need is some water, a cup, and a coin.
Place a cup of water in the freezer and let it freeze.
Before leaving, place a coin on top of the frozen water.
If you return and find the coin at the bottom of the cup, it means all the food has thawed and should be discarded. If the coin remains on top, your food is still good to eat.
Russell's tip has been widely shared, especially in areas prone to hurricanes. Nearly 400,000 people have shared the post on Facebook, proving its popularity and practicality.
