A balloon cannot be fully inflated without inflation. At this time, the volume of the ball is small. After the gas is filled, the volume of the ball becomes larger, and the air discharged by the ball in the air becomes more. The buoyancy of a ball is equal to the weight of the air it displaces.
It is most famous for the colorful ball-patterned objects in Yongzheng period of Qing Dynasty. The Palace Museum in Beijing has a colored ball jar and a colored ball bowl, both of which are typical works. Gan Long's enamel ball pattern is hollowed out to make a bottle of Jiaotai gourd, which is novel and unique.
Influence of rubber ball pattern on weight;
The mass of one liter of air near the ground is about1.29g, which is only equivalent to the mass of three paper clips. The light weight is almost negligible, but as long as the base is large enough, such as the total mass of air in a gymnasium, it is about equal to the weight of an elephant.
Secondly, the difference lies in the different pattern contents. In addition to flowers, there are dragons in the group pattern, and the ball pattern is mostly like hydrangea, so people in Qing Dynasty call it hydrangea pattern.
