It is called the ‘Fizz Saver’ and it is one of the coolest must have contraptions for any party!

You twist the dispenser on to the top of a plastic 2-liter bottle, then flip the bottle upside down to dispense drinks. The soda will stay carbonated and you can pour it right from your fridge or place the dispenser on a table!
