One of the safety principles when using a refrigerator is to unplug it when you go away. However, the reality is that many households leave a lot of items in the fridge and cannot unplug it when they leave. But there are incidents that can occur when there is a power outage causing the freezer to defrost. Sometimes when you go to work all day and come back, you find that the food is thawed without knowing since when.
This power outage incident spoils the food in the refrigerator, especially the items in the freezer. But there is one thing that sometimes the power goes off and comes back, making the food freeze again, which makes you not notice it to handle it in time.
At this time, the coin-filled water bowl will answer you and act as a “guide” to tell you about this power outage incident.
How to make a coin-filled water bowl
First, you pour clean water into the bowl, cup, or tray, and freeze it, avoiding overfilling. When the water has frozen solid, take it out and place a coin on the surface. And put the coin-filled water bowl back into the freezer.
The story of the coin-filled water bowl
When you check the status of the coin-filled water bowl, you will notice the following situations:
– When checking, if the coin is on the surface of the water cup, then the refrigerator is still operating normally, not experiencing a sudden power outage, and the food can be used normally.
– If the coin is floating in the middle of the water cup, then your refrigerator has been cut off and stopped working, but only for a short time. The food may not be spoiled, but you need to carefully check before using it.
– If the coin sinks to the bottom of the water cup, then the refrigerator has stopped working for a long time, causing the ice in the freezer to completely thaw, so the coin sinks to the bottom. In this case, it indicates that the food may have been spoiled, completely thawed during the power outage. It hints that you should take them out for checking and cleaning to avoid them from getting spoiled and contaminating other food.
It is recommended to store ice water in transparent cups or trays like this, so when you place a coin in it, the phenomenon is easier to observe compared to ceramic or porcelain bowls.
Note when making a coin-filled water bowl: To facilitate observation, it is best to use a transparent cup or tray, such as plastic, glass, or transparent plastic. The coin should be a dark-colored coin, so it is easier to observe when needed, instead of using a ceramic or porcelain bowl.
It is crucial to properly store the refrigerator to keep the food fresh, but incidents of power outage and refreezing can affect the quality of the food and have an impact on health. Therefore, you should pay attention when using the refrigerator and avoid causing harm. So, placing a coin-filled water bowl in the freezer compartment is very useful to prevent the situation of a sudden power outage while you are away from home.
