How do I keep an open bottle of soda from going stale?
In either a 3 liter or a 20 oz bottle, how does one keep, after opening, the soda (coke, pop) from going stale and losing it's fizz?
Answers:
#1. Drink it!
#2. Put the cap on TIGHT, and don't store it more than a day or two.
I used to own a handy little device that you used instead of the original bottle cap, and it had a little pump on it that you could pump to pressurize the bottle to supposedly keep it from going flat.
I used to work with a guy that would squeeze his 2 liter bottle when recapping it, to get out as much air a possible, he thought that would help keep it from going flat, I never bothered to tell him he was in fact creating a partial vacuum, (the bottle strains to return to it original convex shape) thus drawing out the carbonation faster!

Facts!
Put a spoon in the opening.
Otherwise, you can find some special pressure corks at Linen and Things and Bed, Bath and Beyond.
They have a little pump on top that pressurizes the air inside the bottle.
Good luck
drink it really fast
keep it really cold. the gas will effuse slower at a lower temperature.
how about drinking it before it goes stale. that way u dont have 2 worry about it.
Don't open it, prick a little hole in top and suck it out.
i have use a tight saran wrap on open bottles of pop and beer and it does help with the longevity of the products.keep it in the fridge too, hope that this helps ;o}
How to Keep Fizz in Your Soda
The secret to keeping your soda alive with plenty of reusable fizz is to keep the soda cold... plain and simple. The higher the temperature, the less the carbon dioxide molecules will dissolve. (By the way, try letting the bottle of soda sit out in the sun before dropping in the breath mints and watch out!) It's especially important to keep the bottle tightly sealed while it is out of the refrigerator since the higher temperature makes the gas want to leave the liquid. Pour yourself a glass of refreshing soda, cap the bottle, and put it right back in the refrigerator. Keep it cold... keep the fizz.
my trick is good only for bottles that can be closed...hence it wont work on an opened can. As others have said, keep it cold. this slows down the diffusing process. also, with plastic bottles, what i do is squeeze it, making the liquid rise, thus pushing out alot of the air, then capping it tightly.
hope this helps.
You all are doing 2 much why get so technical just keep the lid on tight is all i do .You can open it 10 x but just put the lid on tight.
by closing the cap ya moron
It’s the age old soda pop question: “How do I keep my soda from going flat?” Usually it’s the dreaded 2 liter bottle that’s the culprit - at about the 2/3 or 3/4 empty point, you notice the difference in carbonation. Or perhaps you don’t feel like polishing off that 20 oz. of VAULT in one sitting. What’s a pop lover to do?
Contrary to popular belief, devices that pump air back into the bottle, such as the “Fizz Keeper”, don’t work. If you apply chemistry to the problem, you’ll discover that the best it can do is slow down the process of losing carbonation, but not stop it. This is because the CO2 will continue to escape into the empty air between the existing soda and bottle cap (where all the soda you drank used to reside) until an equilibirum is reached. And once enough soda is gone that a lot of the CO2 escapes into this air, your soda will be noticibly flat.
Another popular technique that doesn’t work is squashing your bottles. Trying to do this to your original soda bottle won’t do anything in the long run, because a vacuum will be formed, and eventually the CO2 will escape into the vacuum, inflating the bottle back to its original size.
Well I’m going to tell you how to solve this problem. What’s important is to get smaller bottles that are designed to hold soda (as opposed to water bottles, which are more flexible). I tend to use a set of four 8.5 oz orange plastic soda bottles from Wal-Mart (for their “Kid Soda” brand) for a “whopping” $1. Another option are 10 oz. glass bottles of Canada Dry tonic water (more expensive, but glass is better than plastic at preserving carbonation over many months).
After opening your pop, immediately, but carefully (so you don’t agitate it too much and lose more carbonation), pour what you won’t use into the smaller soda bottles. Fill them as close to the top as you can, then screw the caps on tight. Put in the fridge. You need to have as much soda in the bottle as possible so virtually no CO2 can escape into the area of air between the soda and the cap.
Using anything other than a bottle designed for soda isn’t advised (like water bottles, which are soft and have lots of ridges in them), because they’re more likely to expand as the CO2 attempts to escape, thus more carbonation will be lost.
