Balloon

A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications.

The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases.

Applications

Decoration or entertainment

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. As shown in the photo to the right, they can come in different colors like the rainbow such as red, orange, yellow, green, blue, purple, etc.

The Twenty-One Balloons

The Twenty-One Balloons is a novel by William Pène du Bois, published in 1947 by the Viking Press and awarded the Newbery Medal for excellence in American children's literature in 1948. The story is about a retired schoolteacher whose ill-fated balloon trip leads him to discover an island full of great wealth and fantastic inventions. The events and ideas are based both on scientific fact and imagination, and the descriptions are accompanied by illustrations by du Bois.

Plot summary

The introduction compares two types of journeys: one that aims to reach a place within the shortest time, and another that begins without regard to speed and without a destination in mind. Balloon travel is said to be ideal for the second kind.

The main story begins with the rescue of Professor William Waterman Sherman, who is picked up by a steamship while floating among a strange wreck of twenty deflated gas balloons in the North Atlantic. Sherman, a recently retired schoolteacher, was last seen three weeks ago leaving San Francisco on a giant balloon, determined to spend a year drifting alone. The world waits breathlessly to find out how Sherman could have circumnavigated the globe in record time and landed in the ocean with twenty balloons rather than the one with which he began his journey. After several days' rest and a hero's welcome, the professor recounts his journey before a captivated audience.
