I have uncovered the Holy of Holies...

Ever wondered how to keep your 2 liters from going flat? Well, if you think about it, the answer has been right in front of us. 

At most restaurants the soda is stored room temperature. It is never flat, well, almost never. So, how do they do it? Well like I said, they keep it at room temperature, and they mix it at the source. Well, how does that help us?

Simply, try storing your soda on your counter even after you open it and i bet you it does not go flat, for weeks. I have tried this now with my favorite, Mountain Dew and it's fake cousin (King Soopers brand) and it works.

So, try it and see what happens. It will make it worth actually buying 2 liters!
