Hot air balloon event. Hot air ballooning is the recreational and competitive adventure sport of flying hot air balloons. Attractive aspects of ballooning include the exceptional quiet (except when the propane burners are firing), the lack of a feeling of movement, and the bird's-eye view. Since the balloon moves with the direction of the winds ...
The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, [1] in a balloon created by the Montgolfier brothers.

By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
The first manned hot-air balloon, designed by the Montgolfier brothers, takes off from the Bois de Boulogne, Paris, on November 21, 1783. The first clearly recorded instance of a balloon carrying human passengers used hot air to generate buoyancy and was built by the brothers Joseph-Michel and Jacques-Etienne Montgolfier in Annonay , France.
The National Balloon Museum in 2009. The National Balloon Museum is a non-profit museum in Indianola, Iowa. It was founded in 1975 in short term locations, later gaining a permanent location in 1988. [1] All of the museum's exhibits are about hot air ballooning and gas ballooning. [2] The museum is in the shape of a hot air balloon's gondola. [2]
The drawer chooses a card out of a deck of special Pictionary cards and tries to draw pictures which suggest the word printed on the card. The pictures cannot contain any numbers or letters, nor can the drawers use spoken clues about the subjects they are drawing. The teammates try to guess the word the drawing is intended to represent.
This means that while the mass of lifting gas and mass of displaced air for a given lift are the same as at lower altitude, the volume of the balloon is much greater at higher altitudes. A balloon that is designed to lift to extreme heights (stratosphere), must be able to expand enormously in order to displace the required amount of air. That ...
