The development of dry ski slope

Dry ski slope also called artificial ski slope is a ski slope that simulates the attributes of snow using materials that are stable at room temperature, to enable people to ski, snowboard or snow tube in places where natural, snow-covered slopes are inconvenient or unaviable. With the popular trend, let’s have a brief introduction of its development. 
It was in United Kingdom and Netherlands that firstly become popular while other European countries tend to have access to real snow fields. Great changes have taken place of in the shape and the materials of artificial ski slope. 
Early shapes and materials
Extruded plastic tiles were initially used to mimic snow to ski. The extruded plastic tiles provide grip capability by upward spikes. This artificial ski slope provided little grip and turning capability. The experience was also similar to skiing across ice. Due to bad users’ experience and products performance, this type of artificial ski slope was unpopular.  
Brush material 
With the brush industry continues to thrive, the next stage of in dry ski slope development happened. A well known material is dendix, a by-product of brush manufacturing. Dendix is similar to a short-haired brush with the bristles sticking upward. Since invention, it soon became popular throughout the world. Compared to the previous ski surface, it is a significant advancement. However, there was still a constant threat that it provided little or no impact protection to a slope user when falling. 
Recent materials
The most recent development of dry ski slope is the material provides both impact protection and slope lubrication. Besides, it also offers the ability to perform turns, erect jump, and brake. The ski experience is closer to the feel of real snow. The shape is similar to flammulina velutipes. The surface of dry ski slopes is abundant of small balls. These small balls make the snow board and dry ski slope in a point contact condition no matter ski in any angle ensuring the moderate friction.
