Cluster ballooning was inspired by Larry Walters's experience, although his was not the first. [ 1] On July 2, 1982, Larry Walters (April 19, 1949 – October 6, 1993) made a 45-minute flight in a homemade aerostat made of an ordinary lawn chair and 42 helium -filled weather balloons. [ 2] The aircraft rose to an altitude of about 16,000 feet ...
Balloonfest '86 was an event in Cleveland, Ohio, United States, held on September 27, 1986, in which the local chapter of United Way set a world record by releasing almost 1.5 million balloons. [ 2] The event was intended to be a harmless fundraising publicity stunt.
A toy balloon or party balloon is a small balloon mostly used for decoration, [1] 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 (3.9 to 11.8 in) in diameter.
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 ...
The US Army built the first helium extraction plant in 1915 at Petrolia, Texas, where a large natural gas field averaged nearly 1 percent helium. [6] The United States Navy established three experimental helium plants during World War I, to recover enough helium to supply barrage balloons with the non-flammable, lighter-than-air gas. Two of the ...
A balloon race that took place in Bremen, Germany, in 2009. A balloon release is a ceremonial event in which a number of hydrogen - or helium -filled balloons are launched into the sky. Balloon releases can be done as a prayer ceremony, to create a photo opportunity, to raise awareness of a cause or campaign, or as a competitive long-distance race.
Helium storage and conservation. Helium storage and conservation is a process of maintaining supplies of helium and preventing wasteful loss. Helium is commercially produced as a byproduct of natural gas extraction. Until the mid-1990s, the United States Bureau of Mines operated a large scale helium storage facility to support government ...
Inflatable. Balloons are the most common type of inflatable. An inflatable[ 1] 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 ...
