How to keep 2-liters of soda from going flat?

I like multiple settings, lie the beach, parties, peep shows etc

lie the beach? why would you do such a thing to the poor defenseless beach?

How about squeezing the bottle before resealing it, so there will be very little air left in it?

It took 20 years to figure it out.

Keep 2 bottles in your fridge. What you do is drink one till it's half empty. That's when soda starts getting flat. At that point, open the second bottle and do 50/50 mixes. The result, soda that is never flat. Repeat over time as bottles get half empty.

And yes, it does work and it works damn good.

Don't open it.

100% worthless, the gas does not escape through the seal. It's all a matter of pressures. For a new bottle a little gas escapes into the neck of the bottle and that equalizes the pressure between the void and the liquid, so no more gas escapes. When you open the bottle that built-up gas escapes (hence the hssssssssss sound when you unscrew the cap). When you reseal the cap there's no more pressure there, so more of the carbonation escapes the liquid into the void which is now larger than it was before since you poured out some liquid. When enough gas has fillled the void the pressure then is equalized again and no more gas escapes the liquid. The pump-caps accomplish the same thing, they equalize the pressure between the void and the liquid so that it's not the carbonation filling the void. The pump caps are a pain in the ass though. Luckily there's an easier way.

The void is the issue. As it grows more and more gas escapes into it every time you open the bottle. If you get rid of the void between the top of the liquid and the cap, the gas has nowhere to escape to and the liquid stays carbonated. And how do you get rid of the void? Simple. Squeeze the bottle. That's it. After you pour off a serving squeeze the bottle so that the remaining soda fills the space. That leaves nowhere for the gas to escape to, the pressure stays equal and the soda stays carbonated.

I've seen a lot of places on both sides of that argument and never saw a difinitive answer on if it really helps or not...

It doesn't work. Think about the pressure you feel when the bottle is full. That's the same pressure that is necessary to keep the CO2 in solution. If you squeeze the bottle, it will expand to its original shape due to the internal pressure.

Of course, if there isn't much CO2 available, the bottle will remain in its squeezed form. But the soda will still be flat.

LMFAO :laugh:

So I guess this is just one of those mpossible things....

I squeeze the bottle after it's partially empty to remove as much air as possible before recapping it. And when I get to the last dregs, I just dump it if it's flat. Throwing away 10% of a 2-liter bottle is still megacheaper than buying cans.

the grocery stores around here always seem to have a special on either coke products or pepsi, but never both. i just buy whatever is cheap in cans. 2-liters may be cheaper on a volume basis, but cans are always nice and fresh, and 12 oz of soda is all you really need at a time.

if you actually do the math, 2 liters aren't that much cheaper per oz anyhow.

don't open them.

Hahaha, so funny.
Oh, wait.

Put marbles in the bottle, so the level of the liquid is always up to the brim of the bottle. Make sure you keep the cap on tight.

Alternatively, when it starts getting flat - put a 1/4 teaspoon full of dry ice in the bottle, cap it and shake it up good. Then leave it to rest for a few hours. That should give it quite a punch.

 

[villageidiot111]

I just crush the bottle each time I close it, that way there is never much air in it.

Best sale price I normally see is $2.50/12-pack of 12oz cans.
This comes out to be $0.016 per ounce.
At 67.6 oz in a 2 liter bottle, that's $1.17 for a 2-liter bottle.

I normally see 2-liters on sale for $0.79 so it's a pretty decent savings.

What kind of car do you have, and how much do you spend on gas?
And how much alcohol do you buy at pubs and clubs?

Huh? You buy 2 liters and cans at the same store so it doesn't make any difference.

I think what happens is once you get to a point where there's only the bottom left there's enough air in there that it will go flat anyway no matter how tight it is. Best to try to finish it fast once it gets to that point.

You could also try to pump CO2 in it.

Edit: Damnit, a necro. I thought something smelled dead.

 

[Ancalagon44]

I used to squeeze the bottle so that there is less room for air in it.

These days, I just buy six packs, much easier. And I end up wasting less.

EDIT: Sorry, didn't realize that I was posting in a thread that had been necroed for advertising purposes.

Icap?

 

[Cerpin Taxt]

That product is shit. I won't even bother linking the Amazon listing for it (no free promos for fuck-faced spammers), but suffice to say it has one of the worst set of customer reviews of just about any product I've ever seen on Amazon.

 

[who?]

Slip a balloon into the bottle and inflate it to occupy the space.

This is one of those things that pisses me off much more than it should.

A SQUISHED PLASTIC BOTTLE IS NOT A RIGID CONTAINER.

Also NECRO SPAM.
