In our impression, Africa is a relatively poor country. This country is not only short of water, but also has relatively backward living conditions. Refrigerators are now a necessity for our families. Every family has a refrigerator, but for Africans, refrigerators are a luxury. Many people say that they can go to Africa to sell refrigerators, and they will definitely make money. This is not necessarily true. Even if someone can afford a refrigerator, electricity is also a big problem. If you buy a refrigerator, it still can't be used without electricity, right? Today I will show you what refrigerators in Africa look like. A young man in Africa invented a "earth refrigerator" and many local girls went to propose marriage!

The weather in Africa is quite hot, so food will go bad quickly. At this time, an African guy invented a magic tool, which is an earthen refrigerator. His family used to be in the clay business, and he has loved clay since he was a child. He couldn't bear to eat the things at home, but it was a pity if they went bad. So he wanted to think of a way to store food for a longer time. After trying for a while, he really succeeded.
