The white fog generated at the moment of sublimation of dry ice overflows the whole performance stage, creating a wonderful effect like a fairyland filled with smoke, which is the charm of the dry ice smoke effect on the stage. Good dry ice stage smoke effect and proper coaxing of the stage atmosphere can not only bring the audience a dreamy feeling as if they were in the scene, but also leave you with infinite reverie. Therefore, it is a perfect combination of creativity and technology of stage designers and an indispensable expression method in stage art exhibition. Because the specific gravity of carbon dioxide is 1.5 times that of air, and then it flows down to the stage to form low smoke, so dry ice is used on the stage in this way; If you put dry ice on a large professional dry ice machine and spray it on the performance stage, you will have the feeling of stage spray, and the scene of being shrouded in smoke on the stage performance is made in this way. Several characteristics of good stage smoke effect The modern stage smoke machine is developing rapidly, with large capacity and long distance, storing a large amount of smoke, spraying distance up to 11 meters, and distributing smoke area up to hundreds of square meters. The stainless steel shell has beautiful and unique design, and has the functions of preventing dry burning, automatic temperature control, digital real-time temperature display and so on, with low noise, compact structure, convenient use and long spraying distance. High-quality dry ice co2 CO2 smoke effect has the characteristics of low temperature, persistence, white, overweight, dense and low smoke, no confusion and residue, long stay time on the stage ground and no floating. With the development of science and technology, it is particularly important to absorb and introduce advanced scientific and technical means on the stage in a diversified way. Especially, if dry ice is used properly, the stage art can be fully and maturely displayed, which will bring an incomparable artistic experience to the audience. Therefore, this kind of smoke technology is often used in stage, wedding, celebration, theater, film and television, and evening party to create a white smog-filled dry ice stage cloud fairyland effect. For example, some programs in the National Theatre use dry ice to produce smoke effect, and many film and television works have cloud smoke effect, which is also the function of dry ice.

A perfect stage designer should first have a detailed understanding of the scene space of the performance, and get the data of the stage space plan, profile and the height, width and depth of the theater platform. When entering the stage design desk work, fully understand the creative conception of the script, find out the representative characters' characteristics, plot changes, contradictions and conflicts, imagine the environment needed by the theme, establish the methods and means of expression suitable for the theme, and think about how to achieve the stage effect atmosphere consistent with the plot. At the same time, we should also consider the transformation of time and space, adjust the dry ice machine to a suitable position and control the smoke output, in order to serve different space and time, and even need to configure strongpoint, laser lights, various effect light, etc., to render the atmosphere of the scene, so as to achieve the perfect unity with the music, artistic conception and characters of the scene and reflect the theme of the performance. How much dry ice is needed for a performance depends on many factors.
