Why did you put the money in the refrigerator? So this is a university! !

Are you a person who lives alone and is often away from home? Sometimes we will decide to take a long vacation to go abroad, maybe for a week or two, or maybe students will leave the rental house for a month or two during the summer vacation. Besides cleaning the house before going out and paying attention to the shelf life of food, what else should we pay attention to?

When we decide to leave home for a while, we need to pay more attention to electrical furniture. For example, the refrigerator is very important. It is said that as long as we put a coin in the refrigerator, we can guarantee whether the food in the refrigerator can still be eaten after we go home!

So god (? ⊙⊙‵)

▼ People who have traveled for a long time or just left home for a few months should pay attention to the refrigerator at home.

Unless we move, few people will empty the refrigerator during our absence. After all, there are many foods that can be preserved for a long time, so that we can eat them even if we are away from home for a long time.

But have you ever thought that you may encounter power failure when you go out? During the power outage, the food will begin to thaw, and even if the power supply is restored afterwards, the food may have deteriorated, so even if you go home and see the food in the freezer is still frozen, you will not be at ease.

At this time, just put a "frozen water cup" in the freezer and put a coin on it!

If you come home and find that "the coin is on the top of the cup, which means there was no power failure during this period", but if "the coin ran to the middle of the cup, which means there was a short power failure during this period" (because of the short power failure, the coin sank because the water in the cup melted), then if "the coin has sunk to the bottom of the cup, which means there was a long power failure".

General arrangement:

Coins are on the top floor → the electricity hasn't stopped.

Coin in the cup → short power failure

Coin at the bottom of the cup → Long power failure

As long as a small coin can help confirm the preservation of ingredients (*? `)~

That's what you must do if you want to travel far away in the future! ヽ( ? Do you like this article? Share this article with more people ~
