Abstract: Disclosed are synthetic structured mattresses for bird coop bedding. There is a slab/nesting pad made of a porous plastic foam. In one form the foam is suitable to permit liquid to readily drain through it when the slab is washed. An array of tufts are configured to encourage scratching thereof if a bird is placed thereby. In some forms an upper support surface of the slab may be formed with a depression or cutout suitable to position a laid egg at a defined place. The depression may be formed by molding, or by a two layer structure.

Abstract: A portable beverage dispensing system includes a supply of flat water and a supply of pressurized gaseous carbon dioxide. A first motorless carbonator is configured to receive a portion of the flat water and a portion of the carbon dioxide and to cause a portion of the carbon dioxide to dissolve in the flat water to produce partially carbonated soda. A second motorless carbonator is configured to receive a portion of the partially carbonated soda and a portion of the carbon dioxide and to cause a portion of the carbon dioxide to dissolve in the partially carbonated soda and to produce fully carbonated soda. The system also includes a dispenser for selectively dispensing the fully carbonated soda.
