A mother in Jilin sent isolated rice to her daughter and put it in the snow, but her daughter forgot to take it and it froze into ice! It is understood that at that time, the daytime temperature in Jilin was between MINUS 4 degrees and MINUS 7 degrees, and the temperature at night could reach MINUS 20 degrees to 30 degrees. In such a cold day, food will freeze if it is left outdoors for one minute, not to mention MINUS 20 degrees and 30 degrees. It's not surprising to be frozen into ice bumps!

When the mother delivered food to her daughter, she left without seeing it because the food was placed on the ground alone, resulting in a frozen dish bowl the next day. The temperature in winter is really too low, and the rice bowl will be cold within 5 minutes if it is left outside. So can this mother send it to her children in a thermos bucket?
