Abstract
Artificial snow at ambient temperature is used for skiing and is composed of grains of artificial snow at ambient temperature that include magnetic solid grains. The producing method comprises the following steps: (1) using a crushing apparatus to crush a magnetic material into solid grains; (2) using a mesh sieve to sieve the solid grains at a certain particle size; and (3) bonding a layer of material capable of modifying surface property to the surface of the solid grains obtained from sieving. A trail comprises the artificial snow at ambient temperature.
