Balloon modelling or balloon twisting is the shaping of special modelling balloons into various shapes, often balloon animals. People who create balloon animals and other twisted balloon decoration sculptures are called twisters, balloon benders, and balloon artists. Twisters often perform in restaurants, at birthday parties, fairs and at public and private events or functions.
Two primary design styles are "single balloon modelling", which restricts itself to the use of one balloon per model, and "multiple balloon modelling", which uses more than one balloon. Each style has its own set of challenges and skills, and most twisters practise both styles. Depending on the needs of the moment, they might easily move between the one-balloon or multiple approaches, or they might even incorporate additional techniques such as "weaving" and "stuffing". Modelling techniques have evolved to include a range of very complex moves, and a highly specialized vocabulary has emerged to describe the techniques involved and their resulting creations.
Some twisters inflate their balloons with their own lungs, and for many years this was a standard and necessary part of the act. However, many now use a pump of some sort, whether it is a hand pump, an electric pump plugged in or run by a battery pack, or a compressed gas tank containing air or nitrogen. Twisters do not generally fill their creations with helium, as these designs will not usually float anyway. The balloons for twisting are too porous for helium and the designs are generally too heavy for their size for helium to lift.
The origins of balloon modelling are unknown. The 1975 book by "Jolly the Clown" Art Petri credits "Herman Bonnert from Pennsylvania at a magician's convention in 1939" as being the first balloontwister. [1] Val Andrews, in Manual of Balloon Modeling, Vol. 1, An Encyclopedic Series, credits H.J. Bonnert of Scranton, Pennsylvania as being the "daddy of them all". [2] Jim Church III states, "Frank Zacone from Youngstown, Ohio was doing a balloon act during the 1940s and had been doing the act for some time." [2] Another candidate for first balloon twister is Henry Maar. [3]
Modellers will use an assortment of balloons, usually in various colors. Balloon sizes are usually identified by a number: the most common size of twisting balloons is called a "260", as it is approximately two inches in diameter and 60 inches long. Thus, a "260" is 2×60 inches and a "160" is 1×60 inches when fully blown up. Although these are the most common sizes used, there are dozens of other shapes available as well. [4]
The most common methods for inflation are air pumps similar to bicycle pumps, electric air compressors, and the mouth. Inflating a balloon with the mouth is difficult and can be dangerous. Particularly well-trained and talented twisters, however, can blow-up several balloons at once, and some can even blow up 160s, which are much more difficult to mouth-inflate than the more common 260s, as their narrowness requires a great deal more strength and breath pressure to inflate.
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium, and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction.
A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or Presta. A third type of valve called the Dunlop valve exists, but tubes with these valves can be filled using a Presta pump.
A gag is a device used in sexual bondage and BDSM roleplay. Gags are usually associated with roleplays involving bondage, but that is not necessarily the case. The person who wears the gag is regarded as the submissive partner, while the other is regarded as the dominant one. People may wear gags for a variety of reasons. Some people derive erotic pleasure from a gag, either in a submissive or dominant role. When combined with other physical restraints, the wearing of a gag can increase the wearer's sense of helplessness and anxiety level within a BDSM scene by rendering them unable to speak during sexual activity, which some people enjoy.
A toy balloon or party balloon is a small balloon mostly used for decoration, advertising and as a toy. Toy balloons are usually made of rubber or aluminized plastic and inflated with air or helium. They come in a great variety of sizes and shapes but are most commonly 10 to 30 centimetres in diameter. Toy balloons are not considered to include "sky lanterns", although these too are or were used as child toys in some parts of the world.
A balloon rocket is a rubber balloon filled with air or other gases. Besides being simple toys, balloon rockets are a widely used as a teaching device to demonstrate basic physics.
A ceiling balloon also called a pilot balloon or pibal, is used by meteorologists to determine the height of the base of clouds above ground level during daylight hours. In the past, and sometimes today, a theodolite was used to track the balloon in order to determine the speed and direction of winds aloft. The principle behind the ceiling balloon is that timing of a balloon with a known ascent rate from its release until it disappears into the clouds can be used to calculate the height of the bottom of the clouds.
A rugby ball is an elongated ellipsoidal ball used in both codes of rugby football. Its measurements and weight are specified by World Rugby and the Rugby League International Federation, the governing bodies for both codes, rugby union and rugby league respectively.
The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits in the aorta, approximately 2 centimeters (0.79 in) from the left subclavian artery. The balloon inflates and deflates via counter pulsation, meaning it actively deflates in systole and inflates in diastole. Systolic deflation decreases afterload through a vacuum effect and indirectly increases forward flow from the heart. Diastolic inflation increases blood flow to the coronary arteries via retrograde flow. These actions combine to decrease myocardial oxygen demand and increase myocardial oxygen supply.
Hot air ballooning is the recreational and competitive adventure sport of flying hot air balloons. Attractive aspects of ballooning include the exceptional quiet, the lack of a feeling of movement, and the bird's-eye view. Since the balloon moves with the direction of the winds, the passengers feel absolutely no wind, except for brief periods during the flight when the balloon climbs or descends into air currents of different direction or speed. Hot air ballooning has been recognized by Fédération Aéronautique Internationale (FAI) as the safest air sport in aviation, and fatalities in hot air balloon accidents are rare, according to statistics from the National Transportation Safety Board (NTSB).
Wall studs are framing components in timber or steel-framed walls, that run between the top and bottom plates. It is a fundamental element in frame building. The majority non-masonry buildings rely on wall studs, with wood being the most common and least-expensive material used for studs. Studs are positioned perpendicular to the wall they’re forming to give strength and create space for wires, pipes and insulation. Studs are sandwiched between two horizontal boards called top and bottom plates. These boards are nailed or screwed to the top and bottom ends of the studs, forming the complete wall frame. Studs are usually spaced 16 in. or 24 in. apart.
The mouthpiece is the part of a horse's bit that goes into the mouth of a horse, resting on the bars of the mouth in the sensitive interdental space where there are no teeth. The mouthpiece is possibly the most important determinant in the severity and action of the bit. Some mouthpieces are not allowed in dressage competition.
A plastic worm or trout worm is a soft-bodied fishing lure made of elastomer polymer material, generally simulating an earthworm. Plastic worms are typically impaled onto a hook, and can carry a variety of shapes, colors and sizes, awith some are even scented to simulate live bait.
Japanese manga has developed a visual language or iconography for expressing emotion and other internal character states. This drawing style has also migrated into anime, as many manga stories are adapted into television shows and films.
Soft plastic bait, commonly known as soft lure, soft plastics, plastic bait, worm lure or just worm, is any of a range of elastomer-based fishing lures termed so because of their flexible, flesh-like texture. Soft lures are available in a large range of colours, sizes and particularly shapes, and are typically impaled directly onto a fishing hook like an ordinary bait.
Lawrence “Larry” Charles Moss (born September 25, 1970) is an American artist, writer and educator who works mainly with latex balloons. He is known, in the field of large-scale balloon sculpture as art installation, for creating technically and aesthetically challenging sculptures which often incorporate literary, art and pop culture references.
Henry J. Maar (1921–1992), known as "The Sultan of Balloons", was one of the pioneers in balloon twisting. He appeared for over a decade on episodes of the long running Bozo's Circus. While the origins of balloon twisting is impossible to prove, Emmy Award winning producer/director Joseph Maar has provided evidence that his father, Henry, may be the founder of balloon twisting. Larry Moss calls Joseph Maar's evidence "compelling" but warns that if Joseph Maar is correct then the history of balloon twisting would have to be rewritten. For example, the 1975 book by "Jolly the Clown" Petri credits "Herman Bonnert from Pennsylvania at a magician's convention in 1939" as being the first balloontwister.
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after wind resistance, of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle.
Insufflation is the act of blowing something into a body cavity. Insufflation has many medical uses, most notably as a route of administration for various drugs.
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, or light sources. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. Some early balloons were made of dried animal bladders, such as the pig bladder. 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 a wide range of applications.
