Oooooh. Doesn't it suck when your fizzy drinks go flat? Though soda rots your teeth, and you really shouldn't have that liter of coca cola hanging around in your fridge, what to do when you've twisted open a bottle and can't finish the rest? Well you may think about picking up a SodaKeeper . The little bottle top helps keep pressure in your opened beverage, making all the nice fizzies stay in place for the next time you want to give your pearly whites a corrosive soak. Just pump the balloon at the top, and voilà, next time you order that pizza or need to pull a caffeine-fueled all nighter you'll have something tasty and bubbly fresh to drink.
