KEEP THE FIZZ IN SODA POP

These days with a carton of soda pop costing  as much as a good t-bone steak or a gallon of milk you have to have a way to try and not waste it.
 If you you buy 2 liters of soda most time after you have drunk a cup or two out of it is goes flat. But if you will put the lid back on it , tight but not real, real tight and then shake it good  even if it does fizz it will get hard again and not go flat for at least 2 weeks.  Even a 16 oz. pop will keep by just doing this one simple thing.
But do not shake and shake as the bottle will get to tight and may explode. Let it settle down and do not take the lid back off after shaking it for a few minutes. When taking the lid back off to reuse it make sure you untighten the lid easy.
I have tried this many times and it does work even with the 16oz. sodas or pops as we Ky. people call it. You can keep a empty 16oz. bottle to use if you have a can of pop and just drink half of it. Pour it into the bottle , put the lid back on and shake it. I found this online somewhere in the computer world and gave it a try as we are always wasting pop and it will work. I have told many people about this and they can't believe that they have wasted so many pops. Just make sure it gets hard when you feel of the bottle. Give it a try and see if it works for you.
