balloons are flexible bags that can be pumped with gases, such as helium, hydrogen, nitrous oxide, oxygen, air or water. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or nylon fabric, and can come in different colors. Some of the earliest balloons were made from dried animal pockets, such as a pig's bladder. Some balloons are used for decorative purposes or entertainment purposes, while other balloons are used for practical purposes such as meteorology, medical care, military defense, or transportation. The balloon property, including low density and low cost, has led to various applications.
The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases.

Balloon Decoration
Balloons are used for decorating birthday parties, weddings, corporate events, school events, and for other festive gatherings. The artists who use a round balloon to build are called "stackers" and artists who use pencil balloons to build are called "twisters." Most often associated with helium balloon decorations, recent balloon decorators have been moving toward making air balloon decorations because of the limited non-renewable natural resources of helium. The most common types of balloon decorations include arches, columns, centerpieces, balloon drops, sculptures, and a bouquet of balloons. With the increased talent to rotate balloons and accumulate balloons, the emergence of deco-twisters manifests itself as a combination of stacking techniques as well as twisting techniques to create unique and exciting balloon decor choices.
Party balloons are mostly made of natural latex tapped from rubber trees, and can be filled with air, helium, water, or other suitable liquids or gases. Rubber elasticity makes the volume adjustable.
Often the term "Party Balloon" will refer to a rotating balloon or a balloon of a pencil. These balloons are manipulated to create shapes and pictures for parties and events, usually along with entertainment.
Filling balloons with air can be done by mouth, manual or electric inflater (like a hand pump), or with a compressed gas source.
When rubber or plastic balloons are filled with helium so they float, they usually maintain their buoyancy only a day or more, sometimes longer. Closed helium atoms escape through tiny pores in the latex larger than the helium atom. Balloons filled with air usually hold their size and shape longer, sometimes up to a week.
Even the perfect rubber balloon eventually loses gas out. The process by which a substance or solute migrates from a high concentration region, through a barrier or membrane, to a region of low concentration called diffusion. The inside of the balloon can be treated with a special gel (eg, polymer solution sold under the "Hi Float" brand) that coats the inside of the balloon to reduce helium leakage, thereby increasing the floating time by up to a week or longer.
Beginning in the late 1970s, some of the more expensive (and more durable) foil balloons made of thin, unmoted, and less permeable metallic films such as Mylar (BoPET) began to be produced. These balloons have attractive, often glossy reflective surfaces with color drawings and patterns for gifts and parties. The most important attribute of the metallised nylon for the balloon is lightweight, increasing the buoyancy and its ability to keep the helium gas from escaping for several weeks. Balloon foil is criticized for disturbing the power lines.
Modeling and using in art
Balloon artists are entertainers who twist and tie tubular balloons into sculptures (see balloon modeling). The balloons used for sculptures are made of stretchy rubber so they can be twisted and tied up without exploding. Since the pressure required to inflate the balloon is inversely proportional to the diameter of the balloon, this small tubular balloon is very difficult to inflate initially. Pumps are usually used to inflate these balloons.
Decorators can use helium balloons to make balloon sculptures. Usually this rounded balloon shape limits this to simple arches or walls, but sometimes more ambitious "sculptures" have been tried. Also commonly use balloons as table decorations for celebration events. Balloons can sometimes be modeled to form animal shapes. Table decorations usually appear with three or five balloons in each bouquet. The ribbon is curved and added weight to keep the balloon from drifting.
Drops and releases
The decorative use for balloons is the balloon drops. In a falling balloon, a plastic bag or net filled with inflowed air balloons is hung from a fixed height. Once released, the balloon falls into their target area below. Balloon drops are generally performed on New Year's Eve celebrations and at political meetings and conventions, but can also be done at celebrations, including graduations and weddings.
For decades, people have also celebrated with the release of balloons. This practice is not recommended by the balloon industry, as this poses a problem for the environment and the city. In recent years, laws, such as the California Balloon Act, have been enforced to force consumers and retailers to tether balloons foil containing helium (balloons) with balloon weight. This ensures that helium balloons do not float into the atmosphere, which potentially injures animals, the environment, and electrical wiring. Many states have now banned balloon releases, and organizations such as Balloon Blow have been created to educate the public on environmental issues.
It becomes more common for balloons to be filled with air than helium, because air-filled balloons will not be released into the atmosphere or deplete the supply of helium on earth. There are many party games and school-related activities that can use air balloons as opposed to helium balloons. When appropriate age, these activities often include the added pleasure of blowing up the balloons. In many events, the balloons will contain prizes, and the audience can take balloons to pick up the items in them.
Publishing usage
Balloons are used for publicity at major events. The screen printing process can be used to print corporate designs and logos into balloons. Custom-made printers bubble balloons and apply ink-quality ink through silk screen templates. In January 2008, the New York Jewish Community Relations Council held an exhibition of 4,200 red balloons outside the United Nations Headquarters.
Also in the 1950s at the beginning of the Cold War, activists in Western Europe used balloons for propaganda purposes that would float east in Eastern Europe, which would release newspapers and pamphlets. Today, South Korean activists are using the same balloon method to get information to them in North Korea.
Paolo Scannavino set a record 11 for a giant balloon that came in in 2 minutes.
Water bubble
Thin water balloons, small rubber balloons filled with liquid, usually water, not gas, and intended to break easily. They are usually used by children, who throw each other, trying to get each other wet, as a game, competition, or practical joke. By forcing water out of the open end of a water balloon, it is possible to use it as an emergency water gun.
Solar balloons
The solar balloons are thin, big balloons filled with solar-heated air to reduce their density to gain lift.
Balloon rocket
Balloons are often deliberately released, creating a balloon rocket. The balloon rocket works because the elastic balloon contracts in the air inside it, and when the balloon's mouth is opened, the gas inside the balloon is removed, and because of Newton's third law of motion, the balloon is pushed forward. It's the same way as a rocket.
Glyphs
Balloons filled with hot air or gas buoyant have been used as glyphs since the 18th century. The earliest flight is made with hot air balloons using heated air with a flame, or hydrogen as a lifting gas. Then, coal gas and then still using helium. The airless balloon moves with the wind. A balloon that has a machine to push it is called a balloon air balloon or a hot air balloon.
Medicine
Angioplasty is a surgical procedure in which very small balloons are inserted into blocked or partially blocked blood vessels near the heart. Once in place, the balloon is pumped to clear or compress the arterial plaque, and to stretch the blood vessel wall, thus preventing myocardial infarction. Small stents can be inserted into the angioplasty site to keep the vessels open after the lifting of the balloon.
Balloon catheter is a catheter that has a balloon at the end so as not to slip out. For example, Foley's catheter balloon is inflated when a catheter is inserted into the bladder and secures its position.
Balloon insertion which is then filled with air or fluid can be used to stop bleeding in hollow internal organs such as the abdomen or uterus.

Security and environmental issues
There are some environmental concerns over metal-coated nylon balloons, as they do not decompose or break apart like rubber balloons. The release of balloon types into the atmosphere is considered harmful to the environment. This type of balloon can also conduct electricity on its surface and the released foil balloon can get tangled in the power cord and cause a power outage.
Removable balloons can land anywhere, including in nature reserves or other areas where they pose serious harm to animals through consumption or winding. Due to the dangers of wildlife and the impact of waste on the environment, some jurisdictions even make laws to control the release of mass balloons. The proposed legislation in Maryland, USA, was named after Inky, a dwarf sperm whale that required six operations after swallowing debris, the largest part was mylar balloon. To date, there is no documentary evidence to suggest that the deaths of marine mammals have been associated with foil balloons as the only cause. In the UK, foil balloons sold in major theme parks and zoos have weighted balloons attached to help prevent unintentional release into the environment.
Anthony Andrady says that the release of latex balloons that go down to the sea creates a serious disruption of swallowing and/or attachment to marine animals because floating floating floors in seawater deteriorate much more slowly than those exposed in the air. Balloon producers will often claim that the latex balloon is very safe to be released into the environment as it is made of natural materials and will decompose over time. However, latex balloons can take up to a year to be degraded if landing at sea and during this time it is possible for marine animals to swallow balloons and die from slow starvation if their digestive system is blocked.
NABAS (National Association of Balloon Artists and Suppliers), an organization that organizes itself "The Balloon and Party Professionals Association" and represents the British balloon industry, publishes guides for people who hold balloons.
When the balloon finally returns to the ground, they begin the process of degradation. Latex balloons are mostly used because of their ability to decompose. The problem with this is that it can take at least 4 weeks to show substantial degradation of the polymer in the environment, and about 6 months in the aquatic environment. This problem can have an impact on wildlife both on land and in the water system because animals will disrupt inflated balloons as food, nesting material, or just something to play. When that happens, it can cause negative effects for animals. For example, a bird will use a deflated balloon as a component for its nest. When the eggs hatch, they will get caught in the balloon and it can cause death. Other environmental problems with latex balloons are not a balloon effect on the environment after they rot, but when they are being made. When latex is being produced, it produces greenhouse gases, such as CO 2 , CH 4 , N 2 O. This is an increasing problem, especially in Thailand responsible for 35% of world natural rubber production.
Physics
Air pressure
Once pumped regularly, atmospheric air, the air inside the balloon will have a greater air pressure than the original atmospheric air pressure.
Air pressure, technically, is the measurement of the number of collisions against the surface at any time. In the case of a balloon, it should measure how many particles in a given time space collide with the balloon walls and bounce off. However, since this is almost impossible to measure, the air pressure seems more easily described as density. The similarities stem from the idea that when there are more molecules in the same space, more of them will be headed toward a collision with a wall.
The first concept of air pressure in a balloon to know is the "try" air pressure to get out. With all the bounces on the walls of the balloon (both interior and exterior) there will be a certain amount of expansion/contraction. Since the air pressure itself is a description of the total strength of an object, each of these forces, outside the balloon, causes the balloon to contract slightly, while the inner force causes the balloon to expand. With this knowledge, one would immediately assume that a balloon with high air pressure inside would expand on the basis of a large amount of internal strength, and vice versa. This will make the air pressure inside and out the same.
However, balloons have a certain elasticity in those that need to be taken into account. The balloon stretch action fills it with potential energy. When released, the potential energy is converted to kinetic energy and the balloon returns to its original position, although it may be slightly outstretched. When the balloon is filled with air, the balloon is being stretched. While the elasticity of the balloon causes tension that will make the balloon collapse, the balloon is also pushed back by the constant reflection of internal air molecules. Internal air must exert force not only to ward off external air to maintain "even" air pressure, but also to neutralize the natural contraction of the balloon. Therefore, it requires more air pressure (or strength) than the air outside the balloon walls. Therefore, when the helium balloon is left and floats higher, as atmospheric pressure decreases, the air inside gives more pressure than outside so that the balloon comes from the tension. In some cases, helium leaks out of the pores and the balloon deflates, falling down.
