Method 1
Take a metal spoon, dip it into a container of hot drink so that it absorbs some of the heat, then remove it and it will cool, and then repeat the procedure. The spoon can be a tea spoon or a table spoon (if it fits), it doesn’t matter. The main thing is that metal objects have the ability to heat up quickly, taking away some of the heat, and cool down just as quickly. This helps cool the drink faster.
Method 2
You will need two containers. In the first, you brew the drink by pouring boiling water into it, and rinse the second with ice water (you can use it from the tap). Pour the brewed drink into a cooled mug, and begin to cool the first one. Then repeat the procedure as many times as necessary to achieve the desired temperature of the drink.
These methods are well suited for people who do not like to dilute tea with cold water so as not to lose its taste, or for those who drink coffee. By diluting freshly brewed coffee, you are not giving it enough time to brew. The same applies if the drink contains alcohol. Dilution will “steal” the desired degree and ruin the taste.
Bon appetit!

Instructions
The most popular means of cooling drinks at home and in the country is. Place the container of water in the refrigerator and keep it there until the liquid has cooled. The smaller the container volume, the faster the water will cool. To speed up the process, use the freezer. However, it is necessary to prevent the water from turning into ice. It is not recommended to put very hot food in the refrigerator. water, because it can cause damage.
The liquid cools quite quickly when placed in a container with ice. Fill a plastic bowl with ice and place it in water. It will cool down within half an hour.
If you don't have ice or a refrigerator at hand, try the following. Take a wide cotton towel and soak it generously in a strong saline solution. Wrap this cloth around a water bottle and place it where there is a draft. The more it is blown by the wind, the faster the liquid will cool. In the same way, you can cool a watermelon or melon that has been sitting on the stove for a long time.
Very often, the nearest ones are used for urgent cooling of drinks. To do this, immerse a bottle of liquid in a river or pond, making sure that it does not float away. It can be made heavier by tying some kind of weight or placing it in a plastic bag tied to a stick. Instead of a pond, you can put the bottle in a regular bucket filled with low-temperature water. However, cooling will increase significantly.
To cool a small portion of hot water, take two small ceramic or glass cups with thick walls. Pour the liquid from one to the other until it reaches the desired temperature. In this way you can cool 200 ml of water in just a few minutes.
Every summer, aquarists are faced with a big problem - the need to cool the water in the aquarium. The problem arises not only because the water temperature becomes uncomfortable for the fish, but also because the oxygen content in the water decreases, simultaneously with the increase in carbon dioxide content. There are several ways to cope with the summer heat.
You will need
- - thermometer for water;
- - plastic bottle with water;
- - fan;
- - chiller
Instructions
Use special coolers for aquariums. Such devices are reliable and do not consume much electricity. However, please note that they have their own. They are very expensive (worth less than $500 and don’t count on them), a large aquarium will require several devices, which is an incredible cost. In addition, many of these devices only work if the ambient temperature does not rise above 35° C, which makes them simply useless during abnormal heat in the summer. In addition, these devices are not equipped with their own cooling systems, which means you will have to cool the device itself (most often with a fan).
Try using it for cooling aquariums so-called “old-fashioned” methods. For example, change some of the water in the aquarium daily. Take some of the heated water and replace it with colder water, thereby lowering the overall temperature of the water in the aquarium. In the most advanced cases, replace up to half of all water in the aquarium.
Method two (even more effective). Place ice packs in the aquarium. The main thing is to make sure that the container with ice is well closed, because if a leak occurs, the fish may die due to sudden hypothermia. Place ice packs in the most rarely visited corners of your aquarium, as contact between fish and the pack can end in disaster. Change the bags every 5-6 hours. And one more tip. In extreme heat, keep the aquarium lid open to allow the evaporation of water to help the water temperature. If you keep so-called jumping fish, then cover the aquarium with a mesh with small cells (precisely small, so that the fish do not get into them).
Despite the abundance of dairy products in stores, homemade cottage cheese is not becoming less popular. Food prepared with your own hands can taste incredibly delicate, and it certainly does not contain harmful additives. Fresh homemade cottage cheese is an essential protein for the body, a large amount of calcium, phosphorus and other minerals. A yogurt maker will help the housewife make a valuable and tasty product.
How to ferment milk in a yogurt maker
To cook, you first need to ferment the milk. The best, thick yogurt is obtained from a whole village product. Buy it from a farmer or at the market from a trusted supplier. In extreme cases, you can use milk. Pour it into a food-grade metal pan and heat it to 35-40°C, but under no circumstances let it boil.
After this, you need to put the starter into warm milk. You can use pharmacy calcium chloride (at the rate of 5 ml per glass) or a special bacterial starter, for example VIVO (1 bottle per 1-3 liters). When using the product, please read the instructions for use carefully. Warmed sour cream or warm natural yogurt without fruit additives (0.5 cups per 1 liter) will also work as a homemade starter.
If you are not sure about the quality of village milk, first boil it, then cool it to 35-40°C. After this, it can be used to make cottage cheese.
Mix the milk well and pour it into containers. Close all filled containers, place them in the appliance and close the lid. Turn it on for 4 hours, then let it stand with the containers inside already turned off for 4-5 hours. After this time, open the lid and tilt the device slightly - this will help you make sure that the contents of the cups have thickened.
Cottage cheese in a yogurt maker: the final stage of preparation
After fermenting the milk, you must separate the curd flakes from the whey. To do this, pour the curdled milk into a saucepan and heat in a water bath to about 60-70°C (do not boil!). You can place the containers themselves in hot water if this is convenient. While heating the fermented milk product, stir it at least two or three times.
Place the pan (or containers) of heated fermented milk in very cold water to cool quickly. If you did everything correctly, the whey should quickly separate from the curds.
The hot sun heats up the apartment, and with it your aquarium. Not all its inhabitants will like such tropics. Therefore, the owner will have to think about how to do it in the aquarium even before his pets begin to feel ill from overheating. In fact, there are many ways to do this. If you think about it and approach the matter with imagination, you can find new, original solutions. However, let's talk about everything in order.
Measuring instruments
This is a necessity that is often neglected by beginning aquarists. If you have heat-loving fish or ordinary guppies that normally survive in temperatures ranging from 15 to 30 degrees, then you can sleep peacefully. But barbs and goldfish will stop eating as soon as the water temperature rises above 27. And tropical beauties feel good at temperatures from 24 to 26 degrees. This is not to mention snails and aquarium plants, which cannot tolerate overheating at all. Thus, before thinking about how to cool the water in the aquarium, you must install a thermometer.
Temperature above critical level
You need to start sounding the alarm when the thermometer rises above 26 degrees. In this case, you need to urgently decide how to cool the water in the aquarium. At the same time, if there are a huge number of heating devices, of all shapes and sizes, then with coolers everything is very modest. There are practically no special offers on the market that could make life easier for the inhabitants of your home pond.
First of all, mothers need to think about lowering the temperature in the room in which the aquarium is located. All methods are suitable for this. The ideal solution would be a modern climate control system or air conditioning. In this case, you no longer have to worry about the temperature of the water, except to heat it up for the most heat-loving inhabitants. What if there is no air conditioning in the room, and the sun is beating down mercilessly?
Closing the windows
Since it is quite difficult to cool the water in an aquarium, we will try to create favorable conditions for this. First of all, you can remember the thick curtains that cover the windows. This allows you to avoid heating the water in the aquarium by direct sunlight. However, the air temperature in the room still rises, which means the water will heat up.
In this case, screening films for windows and the aquarium itself are a good solution. The shiny material that covers the inside of cooler bags is ideal for this. This screen allows you to protect your room and home flowers from overheating, and at the same time maintains normal living conditions for fish.
Remembering the school physics course
Speaking about how to cool the water in an aquarium in the summer, it is necessary to remember how cooling can occur? That's right, due to evaporation. To use this mechanism, you need to wrap the aquarium in a thick, wet cloth. As it dries, it will need to be wetted again. Evaporation will cool the walls of the aquarium, and you will achieve the desired effect.
Aquarium cover
When figuring out how to cool the water in an aquarium, do not forget about the simplest method. Open the lid and increase evaporation. Due to this, the water temperature will begin to drop sharply. If you are worried that the fish may jump out, then tighten the top with a thin cloth or gauze.
The second point is aquarium lamps. In extreme heat, be sure to turn them off, as they heat the water themselves.
Size matters
Indeed, if we talk about how to cool water in an aquarium in the heat, then the question immediately arises of what volume we are talking about. A small container literally boils in the sun, and this happens quite quickly. However, it is much easier to cool water in it. If we are talking about a container of many hundreds of liters, then it is more difficult to heat such a colossus, but the reverse process will also be more difficult.
The temperature is much more stable in large aquariums. Here its inhabitants have the opportunity to go to the bottom layers, which do not warm up so much, and wait out the intense heat. Therefore, if you do not have air conditioning, then choose an aquarium with a volume of at least 300-500 liters.
Frequent water changes
The temperature in the bathroom is usually much lower than in others. In the heat, you should have several buckets of water standing here constantly to settle. The rest of the principle is clear. Drain the hot water from the aquarium and add fresh water. However, a sudden change can harm your underwater life. Therefore, it is advisable to perform the replacement partially, 10-15%. If possible, this procedure can be performed every hour.
Water aeration as a way to reduce temperature
Why are many experienced aquarists so concerned about how to quickly cool the water in an aquarium? First of all, because as the water temperature rises, the amount of oxygen dissolved in it sharply decreases. That is, aeration on hot days is very necessary and important. You can use some tricks to do this. For example, move the filter closer to the surface of the water so it creates movement. If you have an external filter installed, install a flute that discharges water above the surface of the water. With the lid open, this will enhance gas exchange and cool the water.
Technology on the verge of fantasy
In fact, today there are already systems for monitoring the life support of an aquarium. They not only heat water, control its hardness and softness, but can also cool it if necessary. This happens with the help of special tanks that are in contact with copper tubes filled with freon. The water passing through them becomes cold. But such systems are too expensive to be popular.
Aquarists usually find their situations much simpler. They remove the lamps from the aquarium lid and install fans in their place. You can simply take a home fan and point it at the surface of the water.
Ice cubes
How do we make cool tea in summer? Throw ice into it and enjoy its taste. The same principle can be adopted if the question arises of how to cool the water in an aquarium yourself. If you have a small aquarium, then simply freeze the cubes and throw them into the vessel. The temperature drops quite quickly, but you need to keep an eye on it, as the water will soon heat up again.
If the aquarium is large, this method is not suitable. You will need several kilograms of ice to normalize the water temperature. Why not? We take plastic bags or plastic bottles (2 liters), fill them with water and freeze them. Now carefully place this vessel on the bottom of the aquarium and observe the temperature. Remember that a large volume of ice will drop the temperature very quickly and greatly, so be prepared to stop the experiment. This is the most effective way. In addition, it can help out if you are going away for a long time and it is very hot outside. Then throw in an ice pack, close the curtains and go about your business.
Using a filter
If you have an internal filter installed, it can become a helper. Since the easiest way to cool water is with ice, you freeze the cubes in the freezer and then open your filter. From it you need to remove the washcloth and what it is attached to. Instead, ice is placed in the container. In this case, the water cools very quickly, so it is important to monitor the temperature and turn off the filter as needed. Don’t forget that beneficial bacteria live in a washcloth. They need to be left floating in the tank, otherwise you may dry them out and they will die.
Let's sum it up
As you can see, there are really many ways. You can choose one of them or use a whole range of measures. It depends primarily on how hot it is outside. If it was hot for one day and the wind picked up, then most likely none of the things described will be useful to you. But if it’s been hot for weeks and the whole house is as hot as an oven, then you’ll have to show miracles of ingenuity so that your fish can survive this summer normally.
During the summer months, overheating of water becomes a pressing and challenging problem for aquarium hobbyists. Fortunately, there are many simple ways to lower the temperature of your aquarium water in a short time.
Most tropical aquarium fish live at temperatures around 24-26C, give or take a couple of degrees in one direction or another. But, in our climate, summers can be very hot, and often the temperature rises above 30 degrees, and this is too much even for tropical fish. At high temperatures, the amount of oxygen in the water rapidly decreases, and it becomes difficult for the fish to breathe. In severe cases, this leads to severe stress, illness and even death of the fish.
First of all, aquarists try to change some of the water to fresh, colder water. But, at the same time, too much is often replaced, and this leads to a sharp drop in temperature (stress) and even the death of beneficial bacteria. You should avoid changing the water too suddenly to cold, but instead change it in small portions (10-15%) throughout the day, doing it gradually.
High-tech methods
It is best, of course, to use modern technologies, although there are proven, simple and inexpensive methods. Modern ones include special stations for monitoring the parameters in the aquarium, which, among other things, can cool water and cool it. Their disadvantages include the price and it is not so easy to buy them; most likely you will have to order them from abroad. There are also coolers and special items that are designed to cool the aquarium, but again they are not cheap.
One of the available methods is to place several coolers (fans from a computer in a simple way) in the lid along with lamps. This is often done by aquarists who install powerful lamps so that the surface of the water does not overheat. This works quite well, since in addition to air cooling, vibrations of the water surface also occur, increasing gas exchange.
The disadvantage is that there is not always time to assemble and install such a thing. You can do it easier if you have a fan at home, direct the air flow to the surface of the water. Fast, simple, effective.
Water aeration
Since the biggest problem with increasing the water temperature in an aquarium is a decrease in the amount of dissolved oxygen, aeration is very important. You can also use a filter by simply placing it close to the surface of the water so that it creates movement. If you have an external filter installed, then install a flute pouring water into the aquarium above the surface of the water, thereby greatly increasing gas exchange. This will cool the water and reduce the harmful effect on the fish.
Open the lid
Most aquarium lids do not allow air to circulate quickly enough, plus the lamps heat up the surface of the water too much. Just open or remove the lid completely and you will already gain another degree. If you are worried that the fish will jump out of the water at this time, then cover the aquarium with a loose cloth.
Turn off the lights in the aquarium
As already mentioned, aquarium lights often heat the surface of the water very much. Turn off the lighting, your plants will survive a couple of days without it, but overheating will damage them much more.
Lower the room temperature
Don't mention the obvious - air conditioning. In our countries it is still a luxury. But there are curtains in every home, and be sure to close them during the day. Closing the windows and closing the curtains or blinds can drop the temperature in the room quite significantly. Yes, it will be a bit stuffy, but on days like these it’s not very fresh outside either.
Well, a fan, even the simplest one, won’t hurt. And remember, you can always aim it at the surface of the water.
Using an internal filter
There is a very simple way to lower the water temperature in an aquarium using an internal filter. Just remove the washcloth, you can even remove what it is attached to and put ice in the container. But remember that the water cools very quickly and you need to constantly monitor the temperature, turning off the filter on time. And the washcloth contains beneficial bacteria, so leave it in the aquarium rather than drying it out in the summer heat.
Ice bottles
The most popular and easiest way to lower the water temperature is to use a couple of plastic bottles with ice. This is almost as effective as putting ice in a filter, but is more spread out over time and smoother. Still, it is important to ensure that the water does not get too cold, as this will lead to stress in the fish. Do not put ice directly into the aquarium, it will melt very quickly, it is difficult to control, and there may be harmful substances in the tap water.
These simple methods will help you and your fish survive the summer heat without loss. But it’s better to prepare in advance and at least put a couple of bottles of water in the freezer. Maybe they'll come in handy.

Lifehack. How to quickly cool a bottle July 30th, 2018
It rained for a month, but it seems to have let up and the heat is starting. Sometimes you quickly want to drink a cold drink. It is clear that you can cool the bottle by throwing it in cold water or, for example, by putting it in the refrigerator. However, it still takes tens of minutes to cool the bottle well.
What if you need to cool it really hard in TWO MINUTES? Can you guess what this simple method is?
All we need to quickly cool the drink is a large enough container, cubed ice, several liters of water, and a little salt. First, you need to pour the fly into the container and fill in all the water that we have. After that, all that remains is to add salt.
When all of the above is done, put a bottle or can of drink into the prepared composition and begin to mix everything, slowly and consistently. You need to mix it properly. To do this, take a large spoon and stir the mixture for two minutes. After this, you can take out the drink and enjoy its life-giving coolness.
The essence of this method is that when salt and ice interact, the latter begins to quickly melt due to the rapid absorption of heat around. If there is a vessel with a warm drink nearby, the ice will literally “suck” the heat out of it. Anyone who skipped chemistry at school knows this!
Does anyone use this feature?
