What's the difference between metal balloons and ordinary balloons?
The difference between metal balloons and ordinary balloons is that there is an aluminum film on the outer layer, and the luminosity and strength of aluminum are different.

There are many kinds of balloons. Now we mainly introduce balloons made of natural latex, which can be used as decorations and arches for the opening ceremony, printed with their own advertising patterns as publicity, printed with photos of married couples as congratulations, decorative balls, new people floats and so on. Now the balloon has become a beautiful landscape, more and more people's favor.

As a toy, balloon was once called "foreign eggplant". There is a small bamboo whistle at the opening of the balloon. When the balloon is filled with air, the exit will make a loud noise when it opens.

Balloons can also be used as decorations and transportation. 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.

Introduction to balloons:

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 in it is lighter than the air of the same volume.

When the generated buoyancy 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.
