If you are thinking of going on vacation and leaving food in the freezer, this is an article you should not miss. Today we shares with you a simple trick that will tell you if it is safe to consume the food that you left in the freezer.

Sometimes when we’re away from home, the power goes off and we never know about it. However, this can cause food stored in the freezer to defrost and deteriorate.

One woman has came up with an ingenius trick on how we can now check if our refrigerators are still in optimal working condition – with just a single mug of water and a penny! With such an experiment, you’d never have to worry about having spoilt vegetables or fruits in your fridge again.

An idea developed by Sheila Pulanco Russell, she demonstrates a fridge-mug experiment with simple tap water. It is an extremely easy experiment – if the penny freezes, its a good sign – your fridge’s able to keep your groceries well-chilled and frozen. If it isn’t, it probably tells you that you’d need to buy a new refrigerator to prevent food spoilage – try this at home now!

In a Facebook post which quickly received hundreds of thousands of reactions and shares, Sheila explains how to proceed. She writes:

“For those of you that are evacuating from the coast, I just heard a great tip. It’s called the one cup tip. You put a cup of water in your freezer. Freeze it solid and then put a quarter on top of it and leave it in your freezer. That way when you come back after you’ve been evacuated you can tell if your food went completely bad and just refroze or if it stayed frozen while you were gone.

If the quarter has fallen to the bottom of the cup that means all the food defrosted and you should throw it out. But if the quarter is either on the top or in the middle of the cup then your food may still be ok. It would also be a great idea to leave this in your freezer all the time and if you lose power for any reason you will have this tip to fall back on.

If you don’t feel good about your food, just throw it out. The main thing is for all to be safe. Please SHARE this on your page. ”

In any case, if you’re not sure whether food is safe, throw it out. The most important thing in life is, and will always be, your health.
