a large vase inside which a smaller vase is inserted, inspired by the old containers used in ancient Egypt, to refrigerate food and liquids, and still used today in developing countries, where there is no electricity
He is about to end up run over, his mother saves himan idea per maintain the temperature of the food? Here she is: the terracotta fridge, which saves on the bill and eliminates the environmental impact.
But what does this sort of alternative fridge look like? It is actually a large vase inside which a smaller vase is inserted - a bit like the matryoshkas game - and was baptized Very dal professor Mohammed Bah Abba.
He made it, probably inspired by the old containers used in ancient Egypt to refrigerate food and liquids, and still used today in Developing countries, where there is no electricity.
You can do it too: you will only need:
- dell 'water,
- two terracotta flower pots, (one bigger and the other small, so that they can go inside each other),
- a little bit of sand,
- a large towel or a very large cloth and just 10 minutes!
So make sure that the sand is well pressed, then put the other jar inside.
2) Secondly, you have to fill the jar with sand: in essence, once you have inserted the small vase inside the large one, you must continue to add sand and fill all the space that remains between the outer perimeter of the small vase and the internal one of the large vase: you must therefore fill the whole with sand the interspace, so that the smaller pot stands upright and is stable inside the large one.
3) At this point, wet the sand with plenty of water which is between the two vases and repeat the operation at intervals, as the water is absorbed by the sand. The first time you do this the water will have to cover all the sand and at a certain point it will seem that you have exaggerated the amount of water, because the sand will tend to almost sink; in reality this is a key phase for the success of the "refrigerator" effect, because the liquid that will remain on the surface will be the one that will then evaporate with the wind and the sun, while the water that has gone down to the depth will guarantee the coolness to your drinks.
4 Now cover the whole structure with a towel or a very large cloth and after about an hour you will find chilled drinks ready to drink!
