How to launch balloons into the sky. Launching balloons. How long can latex helium balloons soar in the sky
All kids and even some adults love balloons. These products are able to give a rainbow mood, a sense of celebration and happiness. decorate the halls for various events. And some buy them specifically to release them into the sky and enjoy the way they soar in the sky. And where Surely everyone at least once in his life thought about this question.
How far do balloons fly?
The height of the flight of a balloon launched into the sky can vary. It depends on these facts:
- The density of the material from which the balloon is made.
- Weather.
- The amount of helium inside the product.
- Wind speed.
Under ideal conditions, the ball can rise almost into space, and this is more than 50 kilometers from the earth.
Where do the balloons go?
Answers to this question can be varied. For example, to answer the kids, you can come up with a magical story about where the balloons fly. This will interest the child and help not to be very upset if suddenly the desired “piece of joy” is lost from the hands and takes off into the sky.
For example, to little boys and girls, you might say the following:
- On a journey through space.
- To your parents.
- To the rainbow
- To the distant country of Shararam, where many such balls live.
- To warmer climes to migratory birds.
Such versions of the answer to the question of where the balloons fly to will certainly please the child. In fact, when the balloon rises high into the sky, it bursts due to pressure and descends back to the ground, but already in the form of a rubber rag.
How long can rubber helium balloons soar in the sky
Knowing where the balloons go, many are interested in which of the products will last longer between heaven and earth. Rubber balls tend to be inelastic and not very strong.
Therefore, having reached a height where helium is replaced by air due to atmospheric pressure, the rubber ball does not withstand stress, bursts and descends to the ground in the form of a piece of rubber, continuing its “life” somewhere in the forest, ocean or in the middle of the street. It is difficult to determine exactly where the balloon will fly after it bursts. But in any case, he gets to the ground.
How long can latex helium balloons soar in the sky
Latex is a material that is obtained from Hevea brasiliensis. That is, it is a natural material. Therefore, even if the product burst under pressure and fell into a pond, in a forest or in the middle of a city, it will not harm the environment. If people check where the balloons fly by using rubber products, then they can harm the environment. But even rubber balls are not as harmful to the ecological system as plastic bottles, which are destructive to the environment.
Why balloons fly away is clear to everyone. The helium with which they are filled is lighter than air, so the rainbow balloon is carried in the wind. As the balloon rises, it is affected by the atmosphere. The air temperature in the upper spheres of the globe is much lower than on earth. Because of this, the interior of the balloon releases helium and fills with air. Under the pressure of cold air, the latex is stretched. The balloon gets heavier. After that, the product begins to soar smoothly and go down.
There were cases when the ball as a whole flew to the ground. Schoolchildren from Canada conducted an interesting experiment. They launched a balloon filled with helium into the sky and fixed a camera on it. The latest pictures were taken at an altitude of more than 35,000 meters.
Experiments were also carried out in the world to launch balloons into the sky along with "passengers". The most popular hero who has risen to the clouds on a balloon filled with helium is the bear, which was the symbol of the Moscow Olympics. There are many versions of where this "pilot" landed. A version believed to be accurate has never been found.
There are also people in the world who have experienced first hand what it is like to fly on balloons filled with helium. One of the experimenters was a resident of America, and he hovered above the ground for more than 13 hours. True, his flight was unsuccessful, he got tangled in the wires, which deprived the settlement of electricity. There was also a man from Russia who was ready to do anything for the sake of science. This man has been at bird's eye view for 25 minutes.
Balloons flying into the sky have different fates. But in any case, this process is interesting for science and deserves attention.
Sky lanterns are known under a variety of names, the people call them both "Chinese" and "wishing balls". It is believed that before releasing a domed structure into the sky, it is necessary to write your desire on it, and then it will certainly come true. But still, first things first, and we will start with detailed instructions on how to launch a sky lantern.
Why let go of your desires into the sky, and where did this tradition come from?
Sky lanterns are often referred to as "Chinese" lanterns. This is not entirely true, since they originally appeared in Thailand. In Russia and Europe, paper lanterns of desires have become popular relatively recently. Today they can be purchased at any holiday supply store or souvenir shop. These products are relatively inexpensive. The answer to the question of whether sky lanterns can be launched is yes. In addition, you can always choose the option that suits you in shape, size and color. The launch of one flashlight looks interesting, and the massive flow of several units into the sky looks especially spectacular.
on one's own?
Remember that the ball of desires is not pyrotechnics, and it can be released into the sky without any special skills and abilities. But still, you should not trust the launch to small children or incapacitated citizens. Read the instruction manual on the packaging of the flashlight. Recommendations are general for products of all shapes and sizes. The flashlight needs to be pulled out of the package and straightened. The burner can be installed immediately, or it must be fixed by yourself. It is more convenient to launch one flashlight together, when someone holds the product by the hoop, and his partner lights it. After you light the burner, you need to hold the dome straightened and allow it to fill with hot air. Even if you do not yet know how to launch a sky lantern, do not be afraid - you have at least a minute of time, and until you release the product, it will not fly away anywhere. During this period, you can take beautiful pictures. Then you release the flashlight into the sky and it quickly shoots up. However, perhaps for some time you will be able to admire its flight.
Where can you launch sky lanterns: secrets and recommendations
The most convenient way is to send the wish balls flying outside the city limits. But if you don’t have the opportunity to go to nature, release flashlights in any place near which there are no houses and other buildings, as well as tall trees. At what time of the year to send your desires to heaven is also unprincipled. But in summer, the flashlight will start much faster than in winter. The weather must be calm, otherwise the balloon will fly crooked and ugly, or even be blown off at launch. Even if you don't yet know how to launch a sky lantern and are about to try it for the first time, be sure to inspect the product for damage. If there are holes, they must be sealed with tape. Do not forget that celestial balloons look much more spectacular at night, but during the day their launch is unlikely to impress anyone.
Most people who have at least once launched a gas balloon into the sky, or have seen others do it, are interested in the question of how far the balloon flies, what will happen to it, and where it will fall. Some even try to launch a balloon with a letter that a person must find and forward it to the addressee so that one can find out how far the balloon flew into the sky. But consider what is the probability that this ball will fall in the city, and that it will be found, and what is the probability that a person wants to send something to someone. Yes, the probability is very small, but we have heard real stories when letter balloons actually found and forwarded letters to the person who launched the balloon. We recommend that you read
WHAT ARE BALLOONS LAUNCHED INTO THE AIR INFLATED
In this case, we are only talking about small balloons that are inflated with gas and launched into the sky, and do not consider large passenger balloons that can be flown. And so, in order to launch the balloon into the sky and find out how far it will fly, you need to inflate it with gas. Hydrogen will be the lightest gas, but since it is very explosive, it is not used to inflate balloons. Hydrogen is followed by Helium gas, it does not explode, is non-toxic and has a high lifting force, which allows it to be successfully used in inflating balloons. Of course, you can inflate a balloon with gas from a home stove, but the lifting force of such a balloon will be extremely small.
WHICH BALLOONS FLY THE LONGEST
In this question, we will consider two types of ball. The first balloon will be latex, inflated with helium and coated with HiFloat, which creates a film inside the balloon and does not allow helium to penetrate through the latex. Without HiFloat, a latex balloon flies approximately 12-24 hours depending on the quality of the latex and the size of the balloon. The second balloon will be foil and inflated with helium. According to a preliminary estimate, such a balloon flies for about 14 days, since the foil does not allow helium to pass through and does not exert pressure on the gas, unlike a latex balloon, which inflates and creates pressure. To find out how long a balloon inflated with helium flies, we conducted tests, see the results below.
What is remarkable is that a balloon inflated with helium flies very far, one might say, into the stratosphere. Due to the difference in pressure at sea level (on the ground) and in the stratosphere, the gas inside the latex balloon begins to push and inflate the balloon with more force, which leads to its rupture. The approximate time for a latex balloon to reach the height at which it bursts is on average 2-3 hours from the moment of launch.

WHAT IS THE LOADING CAPACITY OF A GAS BALL
To find out what is the carrying capacity of one balloon, you can use the following data, where 1m3 of helium lifts one kilogram of cargo minus the weight of the balloon itself. On average, the carrying capacity of one standard balloon inflated with helium will be 3-4 grams. To find out in practice what is the carrying capacity of a balloon inflated with helium, we conducted tests, see the results above.
HOW FAR DOES A GAS BALLOON FLY FLY
To answer the question: “How far will a balloon inflated with gas (helium) fly?”, You need to know a lot of data. The flight range of the balloon will depend on the time during which it will fly, and on the strength of the wind that will move the balloon. A lot depends on weather conditions, in calm weather the ball can fly for a whole month and fall at the place of its launch, and in a strong wind it can fly very far. And so, in order to understand how far a balloon inflated with gas will fly, you need to know the flight time of the balloon and the strength of the wind. Let us assume that the wind strength throughout the entire flight of the balloon will be 3 meters per second, although, in fact, depending on the height and weather conditions, during the flight of the balloon, the wind strength will change both up and down. Now let's calculate: 3m/s * 60 seconds = 180 meters the ball will fly in 1 minute. 180 meters * 60 minutes = 10800 meters (10.8 km) the balloon will fly in one hour. 10.8 km * 24 hours = 269 km the balloon will fly in a day. 269 km * 14 days = 3766 km the balloon will fly in two weeks. The calculation was made from the fact that the wind will blow with a force of 3 m / s all the time the balloon is flying, but since the weather conditions are always different, it is impossible to assume that the balloon will fly that far. In practice, the ball can land even a kilometer from the launch site, or it can go around the entire globe, because the wind strength can be different. Below you will find our practical tests that give the answer to how far a balloon travels when inflated with gas.
In which direction will the balloon, inflated with gas, fly? Of course, the ball will fly where the wind blows, but since the wind blows in different directions in different places and at different heights, it is impossible to predict in which direction the ball will fly, one can only guess. See practical tests below.
ATMOSPHERIC PRESSURE AT DIFFERENT HEIGHTS
As you can see from the plate, the atmospheric pressure above sea level is 760 mm. rt. Art., and at an altitude of 5 kilometers already 405 mm. rt. Art. It turns out that if the ball flies to a height of five kilometers, it begins to experience pressure inside itself twice as strong as on the ground, and such a difference is likely to lead to a rupture of the ball. Therefore, if you want the balloon to fly high and not burst at the same time, then it must be inflated with gas in such a way that it has a margin of safety for a certain flight height. If you want the balloon to fly far, try to inflate it with a margin of safety twice and in such a way that it flies no higher than two or three kilometers, otherwise the balloon will burst and fall.
PRACTICAL TESTS WHERE THE BALL IS INFLATED WITH GAS WILL FLY
How do we test? To find out in practice how far a balloon inflated with helium will fly, it is necessary to launch it and control the flight of the balloon. The most difficult and expensive thing is to control where the ball flies.
OPTION #1
You can control the flight of a balloon inflated with gas using a mobile phone with the option to track the location of a mobile phone turned on. It turns out that in order to conduct tests that give an answer to the question of where and how far a balloon inflated with gas (helium) will fly, it is necessary:
- Mobile phone;
- SIM card with a positive balance;
- Connected service that determines the location of a mobile phone;
- Mobile coverage area;
- Packaging for a mobile phone so that it does not get wet in the rain
- The number of balls is sufficient to lift a mobile phone.
OPTION #2
In some ways, it is similar to option No. 1, but instead of a mobile phone, a GPS tracker will be used with the ability to send SMS messages about your location if there is a GSM signal. This option is more expensive than the first option, but more accurate in indicating your location.

TEST #1
March 20, 2015
Specifications: Mobile phone weighing 61 grams, 1 27" latex balloon, two 18" latex balloons and 5 12" latex balloons. All balloons are inflated with "He" Helium gas and treated with HiFloat. Location requests were made every 10-20 minutes using the MTS "POISK" system. As you can see from the time and place data below, the balls were not always in touch, sometimes they did not get in touch and had to wait a tedious 2-3 hours before the next session. We assume that at this time they were flying over a remote area where there is no mobile coverage. The approximate flight height of the balls at the time of launch is 1-2 km above sea level. It was very important that the balloons did not fly to a height of 10 km or more, since the temperature there is 50 degrees and at this altitude the pressure is much less than at sea level, from which the latex balloons simply burst and the beacon freezes.

TEST #2
dated 07 April 2015
Technical data: Mobile phone weighing 61 grams, 4 latex 18 inch balloons treated with HiFloat and inflated with "He" Helium gas. Location requests were made every 10-30 minutes using the MTS "POISK" system. If during the first test we inflated the number of balloons in such a way that the balloons did not rise above 1-2 kilometers and did not burst from the difference in pressure, then in this test we inflated 4 balloons, which lifted about 100 grams of weight, while to raise the mobile phone, it was enough to inflate 3 balloons. That is, during this test, the balls flew over 10 kilometers in height. The test results are exactly what we expected. Balloons flew about 100 kilometers, from the city of Ivanteevka, M.O., to the city of Egorievsk, M.O.
Presumably the flight developed as follows: see below. From the data received from the mobile phone, it can be assumed that initially the balloon went rapidly up and downwind, reaching a high altitude, communication with it was lost (from 06:26 to 08:00), reaching an even greater height, one or two balloons burst ( strongly inflated) from the pressure difference and the mobile phone began to go down. The phone got in touch at 08:00 in the area with. Gzhel, and in the end, he fell in the area of the village of Barsuki, Yegoryevsky district, Moscow region, and issued all further requests for a location from this area.
Launch site: Moscow region, city of Ivanteevka. Start time 06:00 minutes. The weather is cloudy, the wind is 3-4 m/s NW (it means it is blowing to the SE).
06:00 - Subscriber "Sharik" is located at the address Moscow region, Ivanteevka, intersection of st. Pervomaiskaya and st. Greenhouse within a radius of 900 meters.

17:00 - Subscriber "Sharik" is in the same place where he was at 10:05.
CONCLUSIONS ABOUT THE LAUNCH OF LATEX BALLOWNS
After conducting two tests on launching a mobile phone on latex balloons, we can draw the following conclusions: if you inflate latex balloons so that they do not rise above 2 kilometers in height and treat them with a special compound, they will fly for about 10-15 hours, and the flight range will depend on the strength and direction of the wind. The approximate range will vary from 300 to 600 kilometers. So you probably thought that everyone says that a latex balloon treated with a special composition flies up to two weeks, and here it is only 10-15 hours. Indeed, the balls fly up to two weeks, the tests carried out above are proof of this, but they fly without a load and hold only their own weight. If you attach a weight, then the ball will fly as long as it holds the weight of the load, calculate how much time it will take for yourself based on the percentage of the flight time of the ball and the loss of lift (see above). So, if you inflate the balloons in such a way that they will lift a little more than the weight of a mobile phone, then they will not fly over 2 kilometers in height and will not burst, but fly no more than 10-15 hours. And if you inflate the balloons so that they lift the weight of the load, at least 25 percent more than the weight of the load itself, so that the balloons fly longer, then they fly high and burst, which happened with our second test (the weight of the mobile phone is 61 grams, lifting force of the ball is 100 grams). At the same time, not all the balls burst, but only those that were more strongly inflated. After that, the remaining balls began to descend, so the mobile phone just fell, but not much, since some balls supported it, and the descent speed was small. It also follows from this that all the latex balloons that you release into the air without a load fly over 10 kilometers in height, burst and fall.
Specifications: GSM tracker mini A8 weighing 19 grams (with moisture protection and garters 23 grams), five foil balloons with a load capacity of 8 grams each (40 grams total load capacity), "He" Helium gas. Location requests were made every 10-30 minutes using the MTS "POISK" system. With such data, the balls rise over five kilometers, which means that the margin of safety for each ball should have been more than three times than on the ground. So because the difference in atmospheric pressure on earth and in the sky is different, which means that the force of gas pressure on the ball from the inside at a height will be greater. For details, see the pressure plate at different heights (see above). From the results obtained, it follows that the balls, having reached a certain height, began to experience gas pressure from the inside and the weakest ball burst, which led to the fact that there was no longer enough lift, and the tracker began to smoothly decline and fell.

CONCLUSIONS ABOUT THE LAUNCH OF FOIL BALLOONS
Based on the launches of foil balloons, it can be concluded that a foil balloon flies much longer than a latex balloon, but at the same time it has a very small margin of safety. That is, the latex balloon has the ability to expand, that is, stretch, and the foil balloon does not have such an opportunity. Therefore, when launching a foil balloon, the main task is to calculate the flight height of the balloon and inflate it in such a way that the balloon, having risen to a height, does not burst from the gas pressure from the inside. The risks in launching are such that if you inflate foil balloons so that they fly at a height of up to a kilometer, then their lifting force will be small enough and they will most likely be beaten to the ground by the wind. If a foil balloon is inflated so that it flies at a high altitude, then it is necessary to inflate the gas so much that there is both lift and a margin of safety so that the balloons do not burst from the pressure difference at altitude.
