55-641: Thundersticks , sometimes known as bambams , are long, narrow plastic balloons that are used as promotional noise makers. The noise is created when two thundersticks are struck together. They are most often used at sporting events. Thundersticks, known as makdae pungseon ( Korean : 막대풍선 , lit. ' stick balloons ' ) in South Korea, were created by BalloonStix Korea and first used in 1994 at an LG Twins baseball game. They later gained popularity in North America when they were used by fans of

Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology , medical treatment , military defense , or transportation . A balloon's properties, including its low density and low cost, have led to
165-405: A supersaturated solution can be prepared by raising the solubility (for example by increasing the temperature) to dissolve more solute and then lowering it (for example by cooling). Usually, the greater the temperature of the solvent, the more of a given solid solute it can dissolve. However, most gases and some compounds exhibit solubilities that decrease with increased temperature. Such behavior
220-405: A balloon is inversely proportional to the diameter of the balloon, these tiny tubular balloons are extremely hard to inflate initially. A pump is usually used to inflate these balloons. Decorators may use helium balloons to create balloon sculptures. Usually the round shape of the balloon restricts these to simple arches or walls, but on occasion more ambitious "sculptures" have been attempted. It
275-434: A certain elasticity to them that needs to be taken into account. The act of stretching a balloon fills it with potential energy . When it is released, the potential energy is converted to kinetic energy and the balloon snaps back into its original position, though perhaps a little stretched out. When a balloon is filled with air, the balloon is being stretched. While the elasticity of the balloon causes tension that would have

Also in the 1950s at the start of the Cold War, activists in Western Europe uses balloons for propaganda purposes that would float east over Eastern Europe, which would release newspapers and pamphlets. In 2014, South Korean activists used the same balloon method to get information to those in North Korea. Paolo Scannavino set
385-441: A given set of conditions. An example of a gaseous solution is air (oxygen and other gases dissolved in nitrogen). Since interactions between gaseous molecules play almost no role, non-condensable gases form rather trivial solutions. In the literature, they are not even classified as solutions, but simply addressed as homogeneous mixtures of gases. The Brownian motion and the permanent molecular agitation of gas molecules guarantee
440-410: A given temperature is reached, vapor excess condenses into the liquid state . Liquids dissolve gases, other liquids, and solids. An example of a dissolved gas is oxygen in water, which allows fish to breathe under water. An examples of a dissolved liquid is ethanol in water, as found in alcoholic beverages . An example of a dissolved solid is sugar water, which contains dissolved sucrose . If
495-465: A hazard to animals through ingestion or entanglement. Because of the potential harm to wildlife and the effect of litter on the environment, some jurisdictions even legislate to control mass balloon releases. Legislation proposed in Maryland , US, was named after Inky, a pygmy sperm whale who needed six operations after swallowing debris, the largest piece of which was a Mylar balloon. The Balloon Council,
550-515: A latex balloon is perfectly safe to release into the environment as it is made from a natural substance and will biodegrade over time. A latex balloon can take up to a year to degrade if it lands in the sea and during this time it is possible for a marine animal to ingest the balloon and die from slow starvation if its digestive system is blocked. NABAS (National Association of Balloon Artists and Suppliers), an organisation that styles itself "The Balloon and Party Professionals Association" and represents
605-429: A natural latex tapped from rubber trees , and can be filled with air, helium, water, or any other suitable liquid or gas. The rubber's elasticity makes the volume adjustable. Often the term "party balloon" will refer to a twisting balloon or pencil balloon. These balloons are manipulated to create shapes and figures for parties and events, typically along with entertainment. Filling the balloon with air can be done with

#1732891625306660-659: A number of recorded uses. By the 18th century, people were inflating balloons of cloth or canvas with hot air and sending it aloft, the Montgolfier brothers going so far as to experiment with first animals in 1782, and then, when altitude did not kill them, human beings in 1783. The first hydrogen-filled gas balloon was flown in the 1790s. A century later the first hydrogen-filled weather balloons were launched in France . The first modern rubber balloons on record were made by Michael Faraday in 1824. He used these to contain gasses he
715-405: A permanent electric dipole moment . Another distinction is whether their molecules can form hydrogen bonds ( protic and aprotic solvents). Water , the most commonly used solvent, is both polar and sustains hydrogen bonds. Salts dissolve in polar solvents, forming positive and negative ions that are attracted to the negative and positive ends of the solvent molecule, respectively. If the solvent
770-471: A solution is the concentration , which is a measure of the amount of solute in a given amount of solution or solvent. The term " aqueous solution " is used when one of the solvents is water . Homogeneous means that the components of the mixture form a single phase. Heterogeneous means that the components of the mixture are of different phase. The properties of the mixture (such as concentration, temperature, and density) can be uniformly distributed through
825-480: A trade organization that represents the interests of balloon businesses, claims that there is no documentary evidence to suggest that the death of any sea mammal has been attributed to foil balloons as a sole cause, to date. In the United Kingdom, foil balloons sold at major theme parks and zoos have balloon weights attached to help prevent accidental release into the environment. When balloons eventually return to
880-406: A week. However, a rubber balloon eventually loses gas to the outside. The process by which a substance or solute migrates from a region of high concentration, through a barrier or membrane, to a region of lower concentration is called diffusion . The inside of balloons can be treated with a special gel (for instance, the polymer solution sold under the "Hi Float" brand) which coats the inside of
935-556: A wide range of applications. The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases. He invented them for use in the lab. Balloons are used for decorating birthday parties, weddings, corporate functions, school events, and for other festive gatherings. The artists who use the round balloons to build are called "stackers" and the artists who use pencil balloons to build are called "twisters." Most commonly associated with helium balloon decor, more recently balloon decorators have been moving towards
990-449: Is a description of the total forces against an object, each of these forces, on the outside of the balloon, causes the balloon to contract a tiny bit, while the inside forces cause the balloon to expand. With this knowledge, one would immediately assume that a balloon with high air pressure inside would expand based on the high amount of internal forces, and vice versa. This would make the inside and outside air pressures equal. Balloons have
1045-412: Is a result of an exothermic enthalpy of solution . Some surfactants exhibit this behaviour. The solubility of liquids in liquids is generally less temperature-sensitive than that of solids or gases. The physical properties of compounds such as melting point and boiling point change when other compounds are added. Together they are called colligative properties . There are several ways to quantify
1100-424: Is also common to use balloons as table decorations for celebratory events. Balloons can sometimes be modeled to form shapes of animals. Table decorations normally appear with three or five balloons on each bouquet. Ribbon is curled and added with a weight to keep the balloons from floating away. A decorative use for balloons is in balloon drops. In a balloon drop, a plastic bag or net filled with air-inflated balloons
1155-411: Is becoming more common for balloons to be filled with air instead of helium, as air-filled balloons will not release into the atmosphere or deplete the earthly helium supply. There are numerous party games and school-related activities that can use air-filled balloons as opposed to helium balloons. When age appropriate, these activities often include the added fun of blowing the balloons up. In many events,

When, as is often but not necessarily the case, the sum of the mole fractions of solutes is small compared with unity, the solution is called a dilute solution. A superscript attached to the ∞ symbol for a property of a solution denotes the property in the limit of infinite dilution." One important parameter of
1265-411: Is possible to use it as a makeshift water gun . Solar balloons are thin, large balloons filled with air that is heated by the sun in order to decrease its density to obtain lift. Balloons are often deliberately released, creating a so-called balloon rocket . Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within

Balloon A balloon is a flexible membrane bag that can be inflated with a gas, such as helium , hydrogen , nitrous oxide , oxygen , or air . For special purposes, balloons can be filled with smoke, liquid water , granular media (e.g. sand, flour or rice), or light sources. Modern day balloons are made from materials such as rubber , latex , polychloroprene , or

1595-427: The free energy decreases with increasing solute concentration. At some point, the energy loss outweighs the entropy gain, and no more solute particles can be dissolved; the solution is said to be saturated . However, the point at which a solution can become saturated can change significantly with different environmental factors, such as temperature , pressure , and contamination. For some solute-solvent combinations,
1650-530: The UK balloon industry, publishes guidelines for people holding balloon releases. some of the leading balloon manufacturers have started to recommend avoiding balloon releasing, instead preferring to tie balloons down with weights in order to prevent them from floating away. These recommendations have also been adopted by some industry professionals working with balloons in the fields of design and entertainment. Traditionally balloons are manufactured from plastic . With

Release of these types of balloons into the atmosphere is considered harmful to the environment. This type of balloon can also conduct electricity on its surface and released foil balloons can become entangled in power lines and cause power outages. Released balloons can land anywhere, including on nature reserves or other areas where they can pose

Solute In chemistry , a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which
1815-491: The air inside the balloon will have a greater air pressure than the original atmospheric air pressure. Air pressure, technically, is a measurement of the amount of collisions against a surface at any time. In the case of balloon, it is supposed to measure how many particles at any in any given time space collide with the wall of the balloon and bounce off. Since this is nearly impossible to measure, air pressure seems to be more easily described as density. The similarity comes from

The properties of ideal solutions can be calculated by the linear combination of the properties of its components. If both solute and solvent exist in equal quantities (such as in a 50% ethanol , 50% water solution), the concepts of "solute" and "solvent" become less relevant, but

For example, the balloon of a Foley catheter is inflated when the catheter is inserted into the urinary bladder and secures its position. Insertion of balloons subsequently filled with air or liquid can be used to stop bleeding in hollow internal organs such as stomach or uterus . Humans have intentionally filled bladders, especially actual animal bladders, with air since prehistory. In Ancient Greece, these had

Anthony Andrady says that releases of latex balloons that descend into the sea pose a serious ingestion and/or entanglement hazard to marine animals because balloons exposed floating in seawater deteriorate much more slowly than those exposed in air. Balloon manufacturers will often state that
2035-486: The balloon collapse, it is also being pushed back out by the constant bouncing of the internal air molecules. The internal air has to exert force not only to counteract the external air to keep the air pressures "even", but it also has to counteract the natural contraction of the balloon. Therefore, it requires more air pressure (or force) than the air outside the balloon wall. Because of this, when helium balloons are left and they float higher, as atmospheric pressure decreases,
2090-456: The balloon is expelled out, and due to Newton's third law of motion , the balloon is propelled forward. This is the same way that a rocket works. Balloons filled with hot air or a buoyant gas have been used as flying machines since the 18th century. The earliest flights were made with hot air balloons using air heated with a flame, or hydrogen as the lifting gas. Later, coal gas and later still helium were used. An unpowered balloon travels with

Beginning in the late 1970s, some more expensive (and longer-lasting) foil balloons made of thin, unstretchable, less permeable metallised films such as Mylar ( BoPET ) started being produced. These balloons have attractive shiny reflective surfaces and are often printed with color pictures and patterns for gifts and parties. The most important attributes of metallised nylon for balloons are its light weight, increasing buoyancy, and its ability to keep

The most common types of balloon decor include arches, columns, centerpieces, balloon drops, sculptures, and balloon bouquets. With the increased aptitude for balloon twisting as well as balloon stacking, the rise of the deco-twister manifests itself as the combination of stacking techniques as well as twisting techniques to create unique and interesting balloon decor options. Party balloons are mostly made of

2310-487: The environment and cities. In recent years, legislation such as the California Balloon Law has been enacted to enforce consumers and retailers to tether helium-filled foil ( BoPET ) balloons with a balloon weight. This ensures that the helium-filled balloons do not float into the atmosphere, which is potentially injurious to animals, the environment, and power lines. Many states now have banned balloon releases. It

This is becoming an increasing problem, especially in Thailand which is responsible for 35% of the worlds natural rubber production. At the start of the 21st century, balloon recycling or reuse for other purposes was in its infancy. As of 2020, several balloon manufacturers have developed methods for effective balloon waste disposal , and some manufacturers use recycled balloons to produce other products, such as toys for pets. Once inflated with regular, atmospheric air,

The problem with this is that it can take at least 4 weeks to show substantial degradation of the polymer in the environment, and around 6 months in aquatic environments. This issue can have an effect on the wildlife on both land and in aquatic systems because animals will confuse deflated balloons as food, nesting material, or simply something to play with. When that happens, it can lead to negative effects for

When rubber or plastic balloons are filled with helium so that they float, they typically retain their buoyancy for only a day or so, sometimes longer. The enclosed helium atoms escape through small pores in the latex which are larger than the helium atoms. However, some types of balloons are labelled "helium-grade". These balloons are often thicker and have less porosity. Balloons filled with air usually hold their size and shape much longer, sometimes for up to
