Buoyancy is an upwards force that the air exerts and this helps hot air balloons stay in the air. hot air balloons use burners to heat up the air inside the balloon. the burner is usually fueled with liquid propane. the burner mixes the fuel and air and ignites the mixture which creates a flame underneath the bottom opening of the hot air balloon. once the air inside balloon gets warm the balloon will rise. the pilot controls the balloon by releasing hot air from a vent at the top of the balloon.]]> 2018-05-29 00:15:07 UTC https://padlet.com/kcoster2/ydu77fh571tb/wish/264119729 kcoster2 https://padlet.com/kcoster2/ydu77fh571tb/wish/264417794 The first people to fly in a hot air balloon were Jean-Francois pilatre de Rozier and Francois Laurent d’Arlanders on November 21st 1783 in paris, france. their flight lasted 25 minutes. The hot air balloon they flew in was made by the Montgolfier brothers. The hot air is the first successful human carrying flight technology. Before the first human carrying flight there was another flight that happened 19th of September 1783. The passengers in this flight were a sheep, a duck and a rooster, this flight lasted 15 minutes.]]> 2018-05-30 02:48:42 UTC https://padlet.com/kcoster2/ydu77fh571tb/wish/264417794 kcoster2 https://padlet.com/kcoster2/ydu77fh571tb/wish/264444966 As hot air balloons were first invented to travel places to and from they are now more of a tourist attraction a lot of people like to fly in hot air balloons over beautiful scenery just to relax. but others have hot air balloon racers were a group of a lot of people come together and race in hot air balloons. ]]> 2018-05-30 06:45:29 UTC https://padlet.com/kcoster2/ydu77fh571tb/wish/264444966 kcoster2 https://padlet.com/kcoster2/ydu77fh571tb/wish/264450242 https://youtu.be/QGAMTlI6XxY]]> 2018-05-30 07:11:39 UTC https://padlet.com/kcoster2/ydu77fh571tb/wish/264450242 kcoster2 https://padlet.com/kcoster2/ydu77fh571tb/wish/264676090 At the time of their invention  hot air balloons were usually made of silk, which is suitable for the purpose. but it is very expensive  and difficult to repair. modern fabrics have replaced silk with more lighter and stronger options.Most hot air balloons are made out of nylon now. Tyvek  is sometimes used  with experimental balloons, but its flammability makes it unsuitable for most purpose.]]> 2018-05-31 02:33:16 UTC https://padlet.com/kcoster2/ydu77fh571tb/wish/264676090
