Today, I write what I learned about cleaning a box to save an ice cube in a refrigerator.
It's that a dish surface that is at room temperature melts an ice cube.
The other day, I cleaned the box.
I had been intended to clean since before I had been concerned to go on increase tiny fragments of ices cube.
Then, already there were around twenty ice cubes in the box.
I moved those ice cubes into a deep dish because those were an obstacle.
And I put the dish in a freezer.
Because the ice cubes prevented melting while I cleaned the box.
I finished cleaning the box and I tried to return all the ice cubes from the dish to the box.
But I could not do it.
I could remove only part of the summit of the ice cubes to the box.
Others were closed to each other and became a big ice.
As a result, I could remove only the ice cubes which were able to be taken apart from the dish to the box.
After I removed them, I considered why the ice cubes melted.
In conclusion, an ice cube that touches a dish is somewhat melted by a dish's temperature and freeze again.
In short, an ice cube is melted even so put in a freezer, if using a dish which has above 0 degrees Celsius.
Then they freeze again and adhere to each other become a lump of ice.
I was ashamed that I didn't understand this common knowledge.
