Have you ever came home after the long day at work and noticed that your digital clocks showing the wrong time?
“Certainly there was no power outage!” You might think. Even if it was, you simply cannot know how long there was no electricity, do you?
Maybe it was for a few days, leading to defrost food and its deterioration. When electricity comes back, foods freeze again and you almost do not notice that they were thawed.
As we know, it can be very dangerous, because some foods are at risk of spreading salmonella and other bacteria!
Today you discover a way to still find out if and how long your freezer was without electricity!
You will be able to find out whether the food may be consumed or was too long being in warm.
What you need:
- a cup
Pour water into a bowl and place in the freezer to freeze. When in the cup remains only ice, put a coin on the top of the cup and then return it to the freezer.
When, for example, after the holidays back home, before eating food from the freezer, look at where the coin is!
If the coin is still at the top or possibly in the middle of the ice cubes in a cup, or there was not a power failure or power outage was for a short time, so the water was only partly melted.
If, however, the coin is now at the bottom of a cup, it means that electricity failure was for a long time, so the water completely dissolved, and the coin sinks all the way to the bottom. Then it is better not to consume the foods from the freezer.
Brilliant trick, easy to use. Especially useful when you go on a long trip!
