A balloon is a sealed bag filled with air or other gases. Balloons can be used not only as toys and decorations, but also as vehicles. If the balloon is big enough, the gas inside is lighter than the air of the same volume, and the buoyancy generated exceeds the weight of the airbag and attached objects (such as hanging baskets and hot air balloons), the balloon can rise. So it can be used to carry observation instruments and passengers.
Unmanned balloons loaded with equipment are often used for scientific research on the atmospheric environment at high altitude and sometimes for measuring cosmic rays. In most countries, cities and other places, people like to use balloons as festive supplies to decorate places on festivals to achieve the effect of rendering the atmosphere.
