It is called the "Twist and Sparkle" It is basically a more affordable soda siphon. Williams and Sonoma are selling it for $49.95. From what I can tell you would add your liquid or anything that you wish to carbonate into the plastic bottle, insert a Co2 canister into the top, and screw the top on to add carbonation. It seems like it could come in handy when making cocktails, or any other carbonated beverage. I wonder if the little wand has to be submerged into the "liquid" or if the entire bottle would be carbonated upon the C02.
