FC: Hot Air Balloons
1: Hot air balloons have been around for along time. In fact, the first hot air balloon was made in 1785. A sheep, duck, and rooster had the pleasure of riding in it for all 15 minutes of the new type on journey. It seemed to me that the ride started a trend. Just two months later, another balloon flew for 20 minutes in Paris. This balloon was the first one to hold people in it! As the years went by, there were about four more balloons counted for. Some however, blew up and killed passengers. One man that died was trying to cross the English channel. It was said to be the greatest accomplishment in ballooning for those that could cross it! | History of Ballooning
2: Balloons have changed so much over time, from the first one built to the most recent balloon today! Many more have been made and customized to the builders liking. They still consist of a basket, envelope, and a burner.
3: The basket normally holds passengers, the fuel tank, etc. | The Basket | It is normally woven with two different types of cane. They are flexible and strong enough to support the balloon and its passengers.
4: The Envelope | The envelope is the fabric part of the balloon that holds in the air. | All recent envelopes have been made with fire resistant material to prevent any damage.
5: The Burner | The burner is the most important piece of the whole balloon because it makes it float. | Hot air is less dense then cold air, so when the burner pushes hot air into the balloon, it will rise.
