Why can fireworks be set off at the opening ceremony of the Winter Olympics?

Because fireworks display can play a role in rendering the atmosphere.

General fireworks are fireworks, and the fireworks used in the opening ceremony of the Beijing Olympic Games are a kind of luminous body, which is equivalent to the nature of a signal bomb and is only launched into the air in the form of a grid.

Each "fireworks footprint" consists of 32 fireworks bombs, and the overall pattern is novel and meaningful. 29 "fireworks footprints" step by step towards the "Bird's Nest", symbolizing that the Beijing Olympic Games is coming to us step by step.

Fireworks at the Winter Olympics

In order to uphold the concept of green, open, enjoyable and clean hosting of this Winter Olympics, the director's creative team specially planned the concept of "green fireworks" in the fireworks design. The fireworks design of the opening ceremony was firstly compressed from the duration of fireworks display, and the total fireworks display time was only 1.20 seconds, which greatly reduced the input of production materials and the pollution caused by fireworks display.

Secondly, in order to solve the smoke generated by low-altitude fireworks launch, all products use micro-smoke propellant, reducing the smoke by nearly 80%. In addition, in the arrangement, through the link time, high and low product coordination and other means. Leave enough time for the smoke to dissipate so that the remaining smoke will not affect the presentation of the next fireworks effect.
