INTRODUCTION
Everyone knows that children are natural explorers, they love to ask questions.
In the process of any research, as well as any knowledge, the question plays
key role. It can be said without exaggeration that knowledge begins with
question. Yes, this is true, and this study began with a question.
Where do the balloons go?
Rationale for the choice of topic:
Once, going out with the children for a walk, we took balloons with us,
inflated with helium left after the New Year holiday. We didn't have time to leave
from the porch, as someone let go of the balloon, it was picked up by a gust of wind,
and the balloon flew into the sky. All the children watched the flight of the balloon until it disappeared from
mind. Everyone was very upset because they could not catch the ball, but everyone

Everyone has blown up a balloon at least once in their life. happens
so that, without holding it in your hands, the ball flies away. It doesn't have an engine. He doesn't have
wings. So the children thought about the question: where does the balloon fly?
Problem: Where do the balloons fly to?
Hypothesis: Let's assume that the balls fly into space. Is it true?
But is it right?
To fly a balloon to space, it needs to be as strong as
real rocket. We need to find out what kind of ball it is, what is it made of?
Objective of the project: find out where the balloons go.
2. Find out, with the help of experiments, what "can the ball."
3. Learn to explain the observed, draw simple conclusions.

Analysis of results
As a result of the project, children will know:
1. Where do balloons fly to.
2. How durable are the balloons.
3. When the first hot air balloon appeared
As a result of the project, children will be able to:
1. Perform actions to organize experiments with a balloon.
2. Ask questions, look for answers.
3. See a problem on a specific topic.
4. Formulate a goal, plan tasks.
5. Make hypotheses and test them.

It was in the spring. About four years ago. My son and I were returning from a walk. I held his right hand. And for his left he was persistently pulled with his ribbon by a balloon. Red.
Mom, where is he taking me?
Wants to fly away.
The sky is calling him.
Does he like to fly?
Highly. Do you want us to let him go?
The already bright spring sun and the still cool, absolutely transparent air did not in the least distort the correct blue color of the sky.
Let's go, - agreed the son.
The ball soared over our heads, then froze for a moment, as if not believing in the newfound freedom. And again joyfully rushed up and already a little to the side. With the roof of a twenty-two-story tower, our ball caught up in a matter of seconds.
The helium soul pulled him higher and higher, but we still saw him. Red in blue, for me it's like a long and quickly flashed childhood.
Where do the balloons go? the son asked when the balloon rose so high that we lost sight of it.
Of course, one could lie that the balls fly away to their personal ball paradise. Or tell a fairy tale about how all the balls get to Santa Claus. (My children, by the way, still believe in Santa Claus, and I don’t know how and whether to debunk this belief).
And what do you think yourself? - I say.
And my young researcher immediately suggested that the ball rises first to a height where planes fly, and then even higher - into space.
Do you remember what happened to the balloon that Dunno flew with his friends?
Oh, he fell!
Why did he fall?
It cooled down and began to deflate. So all the balls are falling? And where? Outside the city? I know, there are such a lot of balls.
Balloons are inflated with helium. This is such a gas, it is 7 times lighter than air, so the ball can fly. But this gas easily passes through the walls of the balloon. Therefore, after about 12 hours, the balloon deflates and can no longer fly. Remember how the balls behaved, which we did not let go, but brought home. They hung from the ceiling until evening. And in the morning already shrunken lay on the floor. So in the sky the ball is gradually blown away and falls down, turning into ordinary garbage. Sometimes, when there is no wind, the balloons rise too high very quickly, the pressure inside the balloon becomes much greater than the pressure outside on the balloon - and it bursts. Then the bursting balloon falls to the ground. To notice the fallen balls - there must be a lot of them.
So in Cleveland, in one city in the USA, in 1986, more than a million balloons were released into the sky in one day. For the sake of this event, they even closed the airport for several hours.
And when the balls began to descend, they filled the entire bay, city streets, courtyards. It took more time and money to clean up the trash than it did to launch those balloons.
Where will our ball go?
Ours is likely to rise high and burst. You see, there is almost no wind, and the balloon flew up, not to the side.
And who came up with the idea to launch balloons?
But I will talk about this later ...
Most people who have at least once in their life launched a balloon filled with gas 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 altitude and weather conditions, the wind strength will change both upwards and downwards during the flight of the balloon. 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 will most likely lead to a rupture of the ball. Therefore, if you want the balloon to fly high and not burst, 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 practically 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 RESULTS ===---
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 and higher, 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 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 great height, 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.
06:11 - Subscriber "Sharik" is located at the address Moscow region, Schelkovsky district, Obraztsovo village, within a radius of 700 meters.
06:27 - Subscriber "Sharik" is located at the address Moscow region, Shchelkovo, intersection of st. Polevaya and st. Kosmodemyanskaya within a radius of 450 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, how much time it will take to calculate 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 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.
