Balloon

From the Simple English Wikipedia, the free encyclopedia that anyone can change

A balloon is a bag that is usually filled with gas. This gas can be helium, hydrogen, or air. A long time ago, balloons were made out of animal bladders. Now small ones that are for decoration are made from a thin layer of stretchy rubber or other things.

Balloons are used for many purposes. Some are for decoration. These balloons are sometimes made to look like animals. Hot air balloons are balloons filled with hot air. They can be big balloons that can carry a basket with people and other objects inside. Balloons can also be filled with water. These are called water balloons.
