Claim One:
1. A pressurizable container for preparing therein a carbonated beverage from a water-based liquid and carbon dioxide generating chemical reactants designed to rapidly carbonate the liquid and minimize transfer to the liquid of the resultant products of the chemical reaction, comprising: a. a wide mouth bottle having an opening at the top thereof therein providing access to the contents thereof; b. a carbonation chamber, insertable into said opening in the wide mouth bottle for holding therein the chemical reactants and for substantially isolating the resultant chemical products of the chemical reaction to prevent their adversely affecting the palatability of the beverage, said chamber having upper and lower compartments formed in said carbonation chamber, with a separating wall therebetween, and a tubular passageway centrally positioned in said separating wall and extending therethrough, said upper compartment for holding therein the chemical couple and a quantity of water to promote the reaction and said lower compartment having a bottom sparger surface for releasing the generated carbon dioxide into a beverage in the container, said sparger having controlled porosity to provide a first rapid flow of large bubbles through the liquid and a second moderate flow of small bubbles which rapidly carbonate the liquid and means for preventing the transfer from the upper to the lower compartment of the resultant chemical products while allowing a transfer of carbon dioxide to carbonate the beverage.
