1. Make a semi-circular skeleton first, and fix the bottom with a bucket base. Place the ball gauge at 20 cm. Then the blue and white balloons are evenly inflated and knotted. Overlap the balloons on the semi-circular skeleton just made.
2. In this order, cross and overlap balloons in the same way until the skeleton is complete. The spiral balloon arch with ocean theme can be completed with a little adjustment.

A balloon is a sealed bag filled with air or other gases. Balloons can be used not only as toys, but also as vehicles. There are many kinds of balloons.
2. At present, balloons made of natural latex are mainly introduced, which can be used as decorations, arches of 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.
3. Now the balloon has become a beautiful landscape, and it is favored by people more and more! 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.
