"sickness, or ""the bends"". The reduced amount of dissolved gas in the body means that fewer gas bubbles form during the decrease in pressure of the ascent. Another noble gas, argon, is considered the best option for use as a drysuit inflation gas for scuba diving. Helium is also used as filling gas in nuclear fuel rods for nuclear reactors. Since the ""Hindenburg"" disaster in 1937, helium has replaced hydrogen as a lifting gas in blimps and balloons due to its lightness and incombustibility, despite an 8.6% decrease in buoyancy. In many applications, the noble gases are used to provide"
"Balloon A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, air or water. 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.

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.

"Toy balloon A toy balloon or party balloon, is a small balloon mostly used for decoration, advertising and children's toys. 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"" (hot-air paper balloons), although these too are or were used as child toys in some parts of the world. According to The Journal of the American Medical Association, out of 373 children who died in"

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 option. Party balloons are mostly made of 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. Filling the balloon with air can be done with the mouth, a manual or electric"
"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 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"

Every toy balloon has an opening (or ""mouth"") through which gases are blown into it, followed by a connecting tube known as the ""neck"". Balloons are usually filled by using one's breath, a pump, or a pressurized gas tank. The opening can then be permanently tied off or clamped temporarily. Foil balloons are typically self-sealing. By filling a balloon with a gas lighter than air, such as helium, the balloon can be made to float."

Due to its relatively high boiling point (compared to helium and hydrogen), ammonia could potentially be refrigerated and liquified aboard an airship to reduce lift and add ballast (and returned to a gas to add lift and reduce ballast). Methane (density 0.716 g/L at STP, average molecular mass 16.04 g/mol) is the chief component of natural gas and is sometimes used as a lift gas when hydrogen and helium are not available. It has the advantage of not leaking through balloon walls as rapidly as the small-moleculed hydrogen and helium. Many lighter-than-air balloons are made of aluminized plastic that"

Because of this, when helium balloons are left and they float higher, as atmospheric pressure decreases, the air inside it exerts more pressure than outside it so the balloon pops from tension. In some cases, the helium leaks out from pores and the balloon deflates, falling down. ""Stories Behind Everyday Things""; New York: Reader's Digest, 1980.

The heater or burner is fueled by propane, a liquefied gas stored in pressure vessels, similar to high pressure forklift cylinders. Modern hot air balloons are usually made of materials such as ripstop nylon or dacron (a polyester). During the manufacturing process, the material is cut into panels and sewn together, along with structural load tapes that carry the weight of the gondola or basket.

The balloons are zero pressure difference balloons, and are vented at the bottom. They are only partially inflated when launched, and as they rise up, the lower atmospheric pressure causes them to fully inflate. The bottom of the balloon is attached to a parachute, which is then attached by steel suspension cables to the payload. A flight is terminated by firing an explosive squib which separates the parachute from"

The acid separated the water into hydrogen and oxygen gases. The iron filings absorbed the oxygen gas which allowed the hydrogen to go up through a pipe into a wash-barrel, which had another pipe to the balloon envelope. The freed hydrogen gas then filled the balloon, which had a lifting ability of 60 pounds per 1,000 cubic feet of gas. The balloon was held down to the ground by sandbag"

"Flogo A flogo (for "" 'floating logo' "") or foam balloon, is a shaped mass of lighter-than-air soap bubbles. They are not balloons, as they have no envelope, but consist merely of a raft of soap bubbles filled with helium. They are shaped by being molded repeatedly from the launching machine. It is possible to create foam balloons with a diameter of more than 1 meter. Identical foam balloons can be manufactured with the same machine in quick repetition. Foam balloons are used frequently for advertising purposes, since they can be manufactured easily in the form of company symbols. In"
"nineteenth and early twentieth centuries municipal gas works became common and provided a cheap source of lifting gas. Some works were able to produce a special mix for ballooning events, incorporating a higher proportion of hydrogen and less carbon monoxide, to improve its lifting power. Helium is the only lifting gas which is both non-flammable and non-toxic, and it has almost as much (about 92%) lifting power as hydrogen. It was not discovered in quantity until early in the twentieth century, and for many years only the USA had enough to use in airships. Almost all gas balloons and airships"
"soon after the Montgolfier brothers. There is no need to burn fuel, so a gas balloon can stay aloft far longer than a hot-air balloon. It is also safer if there is no flame on board, since the materials used to make aerostats are flammable. Hydrogen soon became the most common lifting gas for both balloons and, later, airships. But hydrogen itself is flammable and, following several major disasters in the 1930s, it fell out of use. Coal gas comprises a mix of methane and other gases, and typically has about half the lifting power of hydrogen. In the late"

After donning safety glasses and hearing protection a check is made to ensure the needle valve is fully closed. The main valve on the cylinder is then opened, followed by the regulator valve. Next, the needle valve is opened and the balloon begins to inflate. As the balloon reaches the correct size the inflation nozzle will begin to lift. At this point the needle valve is closed along with the regulator valve and cylinder vale. The string is"
