balloon

A balloon is a sealed bag filled with air or some other gas. Balloons not only as toys, decorations, but also as a means of transport. If the balloon is large enough, the inside of the gas is lighter than the same volume of air, resulting in buoyancy over the balloon and attached objects (such as the basket, hot air balloon, etc.) weight, the balloon can rise. So it can be used to carry observation instruments and passengers. Unloaded balloons are often used for scientific research on high-altitude atmospheric environments and are sometimes used to determine cosmic rays.

In most countries and cities and other places people like to celebrate the day when the balloon as a festive supplies to decorate the place, to achieve the effect of rendering the atmosphere.
