It would seem that it can be simpler and more understandable than a balloon familiar from childhood. However, if you think about it, you will have many questions. How, for example, and how do you inflate your beloved balls? Could aero designers have been able to prepare a huge number of them to decorate the holiday, pouting them with their mouth ?! And balls for modeling, having the form of long sausages and used in twisting, are also impossible to inflate without any devices. Let's talk about everything in order.
Air
For decorating rooms, creating unusual shapes or for organizing the discharge of balls from the ceiling at a large event, the balls will be filled with simple air. Do this in the following ways:
· As already mentioned, you can inflate a small number of balloons at home with your mouth. This activity is fun and you can bring all family members to it. You can’t leave children alone while playing or inflating balloons, because it can be dangerous.
· Air designers use a hand pump to inflate a small number of balloons to create compositions and figures, to fill with air balloons (balloons for modeling).
· The electric compressor is used by professionals to implement large projects that require a huge number of balls. Some models come with a set of nozzles to make it easier to inflate different balls. For home use, this device is not suitable, since it costs a lot of money.
These are the most effective methods and devices for inflating balls with ordinary air.
Helium
Hydrogen, neon, helium, methane and carbon dioxide can make balls fly up. Helium is selected from this list because it:
· Non-toxic, safe;
· Has an affordable price;
· Creates good lifting force;
· Not combustible and not explosive.
It is stored and transported in cylinders of different volumes, and the balls are inflated using a gearbox wound on the cylinder. Thanks to helium, we can enjoy fancy arches, garlands, fountains and clouds from balloons.
Gas mixture
Giants are in fashion today. They decorate the holidays, use for photo shoots. Filling this giant with helium is not necessary, and unprofitable. Aero designers partially inflate the ball with helium so that it can fly, while the rest of the space is filled with air using a pump or gearbox. Walking balls are filled in the same way, since a ball blown up by helium will not fly up with weights, and if helium is not enough, it will lie on the floor.
Water
For hooligan purposes, the balls are filled with water, creating a kind of "water bomb." When it falls, it breaks, and water from it is sprayed to the sides. “Criminals” are especially pleased if any passerby is nearby. It is worth remembering that the risk of being caught is too great, so it is better to look for more peaceful fun.
These are the most popular ball filler options. However, in the field of aerodesign every day they come up with something new and creative, so at any time the list may replenish with unexpected points.
What is your holiday associated with? Fun, tasty treats, and, of course, balloons! It seems that picking up the balls is quite simple, but it is not. In this article you will find some tips to help you make balloons one of the main "highlights" of the upcoming celebration.
If you want to surprise the hero of the occasion with an unusual bouquet and you think that fresh flowers are too commonplace, order a bouquet made of balloons. Such a bouquet will not fade for a very long time and, of course, will certainly appeal to the person to whom it is intended!
Balloons can be a wonderful wedding decoration. They will look great not only in the form of arches or wall compositions: you can make balls one of the main "characters" of the holiday. For example, a helium ball with confetti, which bursts at the right time, for example, during the first dance, will be very effective.
Helium-filled balloons will help you to very effectively present any small and fairly light gift. For example, if you put them in a huge box tied with a bow, then as soon as the ribbon is untied, the balls will slowly pull the gift out of the box. Remember: the lifting force of one ball is approximately 1.5 grams! If the thing that you want to present weighs too much, it is not necessary to tie it - such a presentation in any case will be remembered for a long time by all participants of the holiday!
If the celebration will be celebrated in the summer, it is worth remembering that the balls should choose light shades. This is due to the fact that ultraviolet has a destructive effect on latex, which means that the surface of the balls should reflect light.
To keep the balls as long as possible in bright sunlight, you can inflate one ball inside the second: the inner one will maintain the desired shape, and the outer one will take on the destructive effect of light rays.
Do not buy balls in advance: latex deteriorates quite quickly when overheating or overcooling, and it is not always possible to maintain the optimal temperature regime.
It is not recommended to use balls in rooms where temperature changes often occur. This is due to the fact that the air or helium with which the balls are filled quickly loses its original volume when the temperature changes. The balls will begin to deflate, and instead of delighting the guests, their appearance will cast a slight melancholy.
If you need to keep the original composition of the balls as long as possible, use the foil balloons service.
Of course, foil balls are more expensive than usual, but they do not deflate and do not deform within 10-14 days. These balls are perfect for children's parties: kids can take the balls home and use them as toys for a long time! You can also order balls treated with a special polymer compound that “sticks” pores in latex, thereby extending the flight time. Processed balls will delight you up to two to three times longer than regular ones. 
Balls can be a substitute for flying flashlights, which are far from safe and can cause fires. You can order special luminous balls: if you release them into the sky at the time of the culmination of the holiday, the spectacle will be quite spectacular.
If you plan to decorate the room with helium balls, Choose latex or foil balls. Moreover, if the balls soar under the ceiling, it is better to choose round balls without patterns, which no one will see.
If you want your holiday to be decorated with the brightest balls, opt for latex.
Want to decorate the hood of a wedding car with balls? Better abandon this idea: such a “composition” will last no more than one hour, and if the car accelerates to 50 kilometers per hour, the balls will burst immediately.
If you plan to give the holiday a certain amount of “insanity”, then you can use helium balls for other purposes. Helium by inhalation quite funny changes the person’s voice, while it is completely harmless to health. Want your wedding video to be truly original? Let the guests say their congratulations by first inhaling the light helium!
If you decide that balloons will become the best decoration of the upcoming celebration, then you were not mistaken! Bright and light balls will soar above the guests, like butterflies, creating a wonderful festive mood. Use the tips and ideas given above - and the balls will delight you even longer and make the holiday more memorable and original!
Balloons rise because the gas filling them is lighter than the surrounding air. Many gases, in particular hydrogen and helium, have a lower density than air. This means that at a given temperature they have a smaller mass per unit volume than air.
When such light gases are pumped into a balloon, it will rise until the total weight of the shell with gas, baskets, cargo and cables is less than the weight of the air displaced by the balloon. (Since air is considered in physics as a liquid medium, the same law applies here as for bodies immersed in a liquid.) Hot air, which has a lower density than cold air, also rises. Although hot air is not as light as some gases, it is safer and easier to reproduce with propane burners mounted under the neck of a balloon shell, which is usually made of lightweight fabric, such as hardened nylon. Balloons filled with hot air usually remain in flight for several hours, but without additional heating of the air inside the shell, they will gradually lose altitude.
Molecules at different temperatures
- When the air is cold, the molecules move slowly and are close to each other.
- When the air heats up, mythe molecules begin to move faster and diverge to the sides, filling a larger volume.
- Since the heated aircontinues to expand, it becomes less dense.
- When cooling its airmolecules lose their speed, volume decreases, and density increases.
- The balloon lies on its side. Propane burners heat the air inside the shell, which will make it swell and rise up.
- Hot, light air (figure below the text) rises inside the shell and then flows down along its walls. Cold air is squeezed out through the neck, the weight of the casing with air decreases and the balloon rises.
- Pilots maintain or increase flight altitude by periodically turning on the burners. As long as the air inside the shell is hotter than the outside, the lifting force overcomes the force of attraction.
- The balloon decreases as the air filling it cools and contracts. Pilots can accelerate the descent by releasing hot air through a hole in the top of the balloon.
The interaction of pressure, volume and temperature
The interdependence of three parameters. Gas pressure, volume and temperature are interconnected. At room temperature (near figure on the right) the movement of gas molecules inside the vessel creates a certain pressure. If the volume\u003e is less than half (middle figure on the right), the internal pressure doubles. When the air heats up (the far drawing on the right), its pressure increases and the volume increases in proportion to the temperature increase.
Now I plan to promote in the TOP page on the topic of balloons.
I decided to educate the public a little and tell about the balloons facts that may seem interesting. Let's start with them, so!
Popular Balloon Shapes
Probably, you should not talk about the shape of balloons for a long time, everyone knows them. The most popular is the shape of the ellipsoid of revolution - a figure that occurs when the ellipse rotates along one of its axes. The classic ball shape is also popular.
For Valentine's Day, heart-shaped balloons are very popular.
Another popular form of balloons is the so-called "sausage" - a long ellipsoid. This long ellipsoid can be shaped into any shape by bending the ball in the right places. So the shapes of rings, knots, animals are obtained. Great opportunity to show your imagination!
And, of course, there are a huge number of balloons in the form of various animals and flowers.
Types of Balloons
There are various types of balloons, among which the following should be noted:
- Standard balloons from latex.
- Balloons for modeling - those same "sausages" that can be given any shape.
- Packing balloons used as storage for things. They have a wide neck, usually transparent or translucent.
- Double Ponytail Balls used to create complex spatial structures.
- Self-made Balls can inflate independently thanks to a chemical reaction.
- . Usually filled with helium, and inside them there is a weight, which is needed so that the figure does not fly away. As a result, such a figure sways from any breeze.
- Mylar (foil) balloons.
Balloon Filling
Balloons can be filled with both gas and water. Water filling is used for various hooliganism: for example, you can throw such a ball in front of a passerby from the balcony, which gives a sea of \u200b\u200blaughter and positive emotions (usually the passerby is not funny at the same time, although there are rare individuals). This kind of ball was even called the "water bomb."
Of the most popular gases are helium, hydrogen, methane, neon and nitrogen. These gases are lighter than oxygen, which allows balloons filled with them to fly up. The most popular is helium or a helium-air mixture, as this gas is safe and also non-toxic.
