The AEMET has verified that this 2020 is being the warmest year in history in Spain, 1.6 more degrees more than normal . Therefore, we show you some tricks to cool drinks and keep them cold without having to use the refrigerator. It is easy to have a cold drink if we learn how, and with things that we have at home, so take good note of how to keep cold drinks without a refrigerator .
Cold drinks with ice and freezer
It is very easy that at a party where there are many people, no matter how far we have been far-sighted with food and cold drinks, the latter run out quickly. The best way to keep a large quantity of cold drinks without a refrigerator is to use a large bowl, pour a large quantity of ice (we will always have a gas station on hand if our freezer does not have enough capacity) and use plenty of table salt.
In less than 10 minutes we can enjoy cold drinks without a refrigerator, perfect to consume. We should not add the salt in handfuls and without measure. We must calculate more or less one tablespoon for each bowl or bowl of water that we pour into the basin. If this bowl is large we can cool enough drinks.
Once we add the salt, we stir well to mix with the ice and water. What we will achieve is that the ice melts faster due to the effect of the salt, so that the water will quickly drop in temperature and will be frozen . We can put both cans and glass bottles, which will cool down in a short period of time, and which will stay cold for quite some time.
We can also use this trick to go on an excursion, putting ice, water and salt in a cooler. If we go to the different beaches we will have the peace of mind of knowing that our drinks will remain cold until it is time to consume them.
Another option, if we go on an excursion to places where there are rivers and lakes, is to submerge the cooler halfway in the water, and it will keep the drinks cold for longer, since rivers or lakes tend to have quite cold water.
Sprays, isothermal bags and the freezer
Isothermal bags are designed to maintain the cold chain of frozen products in purchases and transport, but they also serve to keep drinks cold without a refrigerator, since they keep the cold for about two or three hours .
These bags keep the temperature between two and eight degrees . A good option is to freeze the cans or glass bottles in the freezer (be careful, the glass bottles must be put in the freezer with paper, since the glass, with sudden temperatures, can explode) and later, put the drinks in the isothermal bag. If we are going to go out to the beach, it is a good substitute for the cooler.
If we are at home and we have run out of cold drinks, the solution is to put thick glass glasses in the freezer . In a short time they will be frozen, and we can already serve a drink of the time in them, which will be cold to consume. Compressed air sprays, commonly used to clean camera lenses or computer keyboards, also serve to keep drinks cold without a refrigerator.
If we put the spray upside down, its content will not come out, but the canister will expel the gas under pressure it contains, which will be at sub-zero temperatures. Applying this gas to bottles or cans of drinks is very effective, even these can be frozen in a few minutes.
What is evaporative cooling?
If we have wondered how it is possible that the jugs keep the water cold for so long, the secret is in the mud, and with this trick it will be possible to keep drinks cold without a refrigerator for much longer.
In a clay pot or container we put sand to insulate it thermally . Then we add water and cover with a towel that is wet and cold. As the water evaporates, the inside of the pot will cool down, and you can put the cans and bottles into the container and let them cool. The result is perfect.
If we don’t have a clay pot, we can also use this evaporative cooling system in another way. Soak a towel with cold water . We can also use newspaper, and then we use it to wrap bottles or cans. As the water evaporates, the drink will cool down.
If we are in a place with cold ground, we can cool bottles and cans by burying them for a while under the ground, as long as it is cold and wet. This method keeps the bottles cold although it is not usually as fast as the others.
