 Artificial Snowflake Course Presentation

 

 When a mass of air has reached saturation for ice crystals, it has not yet reached saturation for water droplets. At this time, water vapor in the clouds condenses on the surface of ice crystals, while supercooled water droplets evaporate, leading to the phenomenon of "adsorption" of water vapor from supercooled water droplets onto ice crystals. In this case, ice crystals grow very quickly. Additionally, supercooled water is very unstable. The moment it is touched, it freezes. Therefore, when supercooled water droplets and ice crystals collide in mixed clouds, they freeze and adhere to the surface of the ice crystals, causing them to rapidly increase in size. When small ice crystals grow large enough to overcome air resistance and buoyancy, they fall to the ground, which is how snowflakes are formed.

 

 

Experimental Objective: Understanding Artificial Snow

What is artificial snow?

•Artificial snow is a high-tech chemical product, the chemical properties of the polymer, artificial snow uses its permeability to water (water molecules penetrate into it). When water molecules come into contact with the polymer, they expand from the outside to the inside, and the snow powder becomes smaller particles. After absorbing water, the appearance is indistinguishable from real snow, which is pure white and crystal clear. It does not melt at high temperatures, feels cool to the touch, and has the feeling of snow.
Experimental Procedure: Add the snow-making powder to the box, and then add an appropriate amount of warm water in the ratio of 1:25 (the actual application should be based on the saturation level of the artificial snow). We will find that the snow-making powder rapidly expands when mixed with water, gradually turning into pure white and crystal-clear snowflakes.40
