Usually the round shape of the balloon restricts these to simple arches or walls, but on occasion more ambitious "sculptures" have been attempted. A pump is usually used to inflate these balloons.ĭecorators may use helium balloons to create balloon sculptures. Since the pressure required to inflate a balloon is inversely proportional to the diameter of the balloon, these tiny tubular balloons are extremely hard to inflate initially. The balloons used for sculpture are made of extra-stretchy rubber so that they can be twisted and tied without bursting. Sculptureīalloon artists are entertainers who twist and tie inflated tubular balloons into sculptures such as animals (see balloon modelling). Foil balloons have been criticized for interfering with power lines. The most important attributes of metallised nylon for balloons are its light weight, increasing buoyancy, and its ability to keep the helium gas from escaping for several weeks. These balloons have attractive shiny reflective surfaces and are often printed with color pictures and patterns for gifts and parties. īeginning 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. 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 the balloon to reduce the helium leakage, thus increasing float time to a week or longer. 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. However, a rubber balloon eventually loses gas to the outside. Balloons filled with air usually hold their size and shape much longer, sometimes for up to a week. These balloons are often thicker and have less porosity. However, some types of balloons are labelled "helium-grade". The enclosed helium atoms escape through small pores in the latex which are larger than the helium atoms. 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. These balloons are manipulated to create shapes and figures for parties and events, typically along with entertainment.įilling the balloon with air can be done with the mouth, a manual or electric inflater (such as a hand pump), or with a source of compressed gas. Often the term "party balloon" will refer to a twisting balloon or pencil balloon. Twisting balloons can be used to create decor centerpieces for events and to create a more unique look than can be provided by foil balloons. 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. The most common types of balloon decor include arches, columns, centerpieces, balloon drops, sculptures, and balloon bouquets. 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 the creation of air-filled balloon decorations due to the non-renewable natural resource of helium limited in supply. ĭecorations made of balloons with a combination of stacking and twisting techniques showcasing the deco-twisting style.īalloons are used for decorating birthday parties, weddings, corporate functions, school events, and for other festive gatherings. The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases. ![]() A balloon's properties, including its low density and low cost, have led to a wide range of applications. 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. Some early balloons were made of dried animal bladders, such as the pig bladder. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. ![]() For special tasks, balloons can be filled with smoke, liquid water, granular media (e.g. Balloons are given for special occasions, such as birthdays or holidays, and are often used as party décor.Ī balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, and air.
