Coca Cola out of bubbles ? I'm pretty sure everyone had this problem. It's not tasty anymore. But stop throwing Coca Cola. There is a way how you can carbonate any drink, even still water and transform it into soda drink. You can recharge any beverage which is out of bubbles. In my case it's Coca Cola.
You need Coca Cola or any still drink, empty bottle, baking soda, veniger and small pipe.
