Cream seems to be harmful to your health.
The reporter investigated some snowflake sprays used in festivals and found that there was no description of the main components in the cans. Several merchants said that the price of snowflake spray ranged from 2 yuan to 10 yuan, and the sales volume was relatively large during the festival. The relevant person in charge of the provincial quality inspection and supervision center said that there is no manufacturer producing snowflake spray in Kunming at present, and the center has not tested and analyzed the components of this spray. The reporter found on the Internet that such articles usually contain polyester acid, toner, surfactant and fast foaming alkane solvent. Whether these things are harmful to human body or not, it is wrong for many people to use them to enhance the holiday atmosphere.

Some people use scientific principles to find the material of cotton in diapers, a kind of "polymer water-absorbent resin", which will instantly become artificial snow when added with water, even at room temperature of 25 degrees.
Or? Will cotton candy and a little sequins have the effect of water and snow?

Artificial snow is a high-tech chemical product, a high-molecular chemical substance, which means long-chain molecules. Artificial snow uses its permeability to water (water molecules penetrate into it). When water molecules come into contact with polymers, they expand from the outside to the inside of the polymers. Polymer chain is elastic, but it can only be extended to a certain length, and can't be extended any more. The product is fine and granular, and the appearance after water absorption is the same as that of real snow. It is white, crystal clear, does not melt at high temperature, feels cool, discerning, nontoxic, harmless and pollution-free. This product can also be used for counter decoration, Christmas decoration, film and television, stage scenery, etc. Product description: 1Kg artificial snow can absorb 25Kg of water (the effect is the best at this time). After water absorption, when the paving thickness is 10 cm/3 cm/ 1 cm respectively, 0.3/1/3m2 of artificial snow 1Kg can be paved. The absorbed artificial snow can be stored for about 2-3 days under strong outdoor light, and it can be stored for about 10 days indoors (without direct sunlight). After losing water, you can sprinkle some water on the surface, and the artificial snow will swell again. ? Product packaging: three-layer moisture-proof plastic woven kraft paper bag, 20kg/ bag; Or bulk bags of various weights. Note: 1. What is the ratio of artificial snow to water when adding water? 1:25。 (In practical application, the water absorption saturation of artificial snow shall prevail)? 2. Add water or snow first. ? It is best to use warm water if possible. ?

Artificial snow. Under certain temperature and humidity conditions, the snow maker sprays high-pressure water through the nozzle to form tiny water mist. At the same time, the high-pressure air generated by the air compressor is mixed with the high-pressure water and sprayed through the nozzle of the nuclear reactor to produce seed snow particles. Due to the action of high-power fan, these seed snow particles combine with the tiny water mist sprayed from the nozzle during the spraying process to form the snow particles we need. Snowmakers can be divided into two categories: fixed and mobile. The stationary snow machine is mainly used in large ski resorts in alpine snow fields, which requires a central air compressor and a central water supply system. Snow production is large, but the cost is relatively high. The mobile snow maker is equipped with wheels, and only needs a simple air compressor and water supply system, so the cost is low.
