HOW TO MAKE COLD WITHOUT A FRIDGE?

A real useful lifehack that can decide many problems!

Friends, to tell you the truth, I even couldn't imagine that people use this method so often, but they do!

I was in the market open air yesterday. The weather is very hot now!
+30 degree Celsius or even more!

But sellers need to sell their products in any weather.

I saw some people who had fruits and vegetables in a very strange construction - in 2 pots!

One small pot with fruits stood in a bigger pot, and there was sand between them!

I was so interested that I decided to ask what it was.

And the seller explained mt that it was their handmade fridge!!

I touched fruits and they were really cool!!!

When I came home I googled and found out an amazing fact!

This method was created by Nigerian teacher Mohammed Bach Abbah, and he got 100,000$ premium of Rolex Award for it!!

A small pot is placed inside of a large pot, the space between them is filled with moist sand, the entire structure is covered with a wet cloth.

The water gradually evaporates, taking away the heat from the contents of the inner pot, cooling it! The efficiency of such a refrigerator is quite high - the temperature decreases relative to the surrounding 15-20 degrees Celsius

So simple and so brilliant!

And so cheap! No electricity! No devices, just pots and sand!
