The main component of snowflakes or ribbons sprayed by "snow spraying" is polymer resin composite. According to the principle of similarity and compatibility, this substance can only be dissolved in organic solvents such as ethanol, methane, ethane, propane and butane, and these organic solvents are flammable, so Christmas snow sprays and ribbons made of this raw material are also flammable. In the production process, merchants usually liquefy these organic substances by pressurizing and cooling, and then seal them in bottles. So when the valve is pressed, these organic gases will spray snowflakes and colored stripes at high speed.

When using "snow spraying", citizens must pay attention to safety and stay away from all kindling. Do not spray in flammable and explosive storage places or near gas stations. Don't spray for more than 3 seconds, don't let children play, don't spray on people's faces; If you accidentally spray it on your eyes, rinse it thoroughly with water immediately or seek medical attention immediately.
