ABSTRACT:
A method for creating an ice-skating rink comprising an excavation in the ground lined with polyethylene and filled with salt water; a pump and sprayer used in the winter to build up a layer of salt ice on top of the salt water and to eventually fill the excavation with frozen salt water in this manner, with the pump drawing salt water from beneath the salt ice as the freezing process progresses; covering the salt ice with a layer of straw or layers of air supported reinforced plastic during the warm weather months; circulating air or water over the salt ice and then through channels cut into the ice of the ice rink; laying aluminum foil on the skating surface and freezing more ice over it; and providing an enclosed air supported bubble over the ice with a secondary air supported inner ceiling having an upper facing aluminum surface thereon to reflect infrared radiation coming from the main outer bubble.
