A home carbonation device uses a tube to form a gas-tight seal between two separate existing soda-pop bottles. A threaded cap holds flanges on the tube tight against the opening of each bottle. The liquid to be carbonated is contained in one bottle, while the chemicals for producing carbon dioxide are placed in the second bottle. To keep the chemical reactants from reacting while the gas-tight seal is made, a tall thin cylinder in the second bottle acts as a barrier between reactants until the bottle is placed on its side, at which point the chemicals meet and react producing the carbon dioxide that passes through the tube and carbonates the liquid.
