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

[who?]

If you squish the empty bottle and put the cap back on it won't reexpand. Seems pretty rigid to me. If the goal is to minimize the gas space inside the bottle squishing the bottle and putting the cap on should do the trick but I haven't actually tried it. Have you tried it Welshbloke?

Maybe they use a different type of plastic in the U.K..

What? A squished bottle filled with effervescent liquid won't expand when the pressure in the bottle increases?

Not if you keep squeezing it.....FOREVER!:twisted:

Are we talking about the fappening again?

Squeezing a bottle lowers the amount of non-pure C02 gas in the bottle thus limiting the drop in partial pressure of C02 which limits how much will come out of solution. Therefore, squeezing a bottle helps preserve the carbonation unless you go nuts with the bottle shacking it up.

This is precisely because the soda bottle is non-rigid. If the soda bottle was more rigid it would spring back to it's shape, plummet the pressure inside the bottle and cause all the C02 to escape the soda.

Put in dry ice.

EDIT: This may be EXTREMELY UNSAFE. But you will have a carbonated beverage, for sure.

holly necro batman!

a nearly 10 year necro..wow.

How many people here remember when glass bottles were the norm?

That's exactly what happens when the pressure in the squished bottle goes up due to the gas escaping.

Put in dry ice.

The Pepsi Boss, glass bottle with a styrofoam label. And they were 64oz back then, not 2 liters. Worst packaging idea ever, they weighed a ton. Of course I was about 5 years old at the time, so a 2 liter bottle of soda would have seemed heavy even if it was plastic.

Dr. Pepper tastes better in a glass bottle than in any other container.

Actually I was talking about the 16-20 ounce bottles.

Still relevant so no need to lock.

What if you put a cap with a long straw into the two liter bottle with a valve. Then have a small compressed co2 thing inside like on the Guinness cans.

When you press the button coke pours into your glass. It would be like a mini coke keg.

Just drop a metos in there after you have taken out the first glass of soda, works every time honest.

6 pack of 24oz bottles costs the same as 2x2L bottles so thats my solution.

I remember tghe glass Pepsi's with the Styrofoam labels. I think every one I drank I had to peel the label off. I don't remember the 64oz one but the 16 or whatever the normal size was, I loved them.

add some yeast and then bottle it and cork or cap the bottles. They will ferment, turning some of that sugar into alcohol, which will also increase the carbonation. Be careful though, because the bottle may burst if you are careless.

It's totally not cost effective to buy about 10 grams of dry ice just to do this. And unless you have a super expensive refrigerator, there's no way to keep dry ice around.

Buy a soda stream. I got one and also got 4 extra empty canisters. Just this last weekend, I bought 5 lbs of dry ice from the local distributor and refilled my canisters. It took some doing since I had to crush the ice first with a mallet.

Tips: Use a rubber strap wrench to hold down the canister and remove the brass valve. Use teflon tape, not teflon paste because the paste can fall into the canister eventually. When re-attaching the valve, undo the pressure release valve. It is much easier to attach the valve when there is no pressure.

Turn it upside down.

I've been using Fizz Keepers for over 15 years (yes, bought that long ago.) Lots of awesomeness in these things (especially if they make them now with the same quality.) Finally one broke the other day. Only downside is when using them in a bottle with little soda, it may take 20-30 quick pumps to add enough pressure to the bottle.

Safe to say it's flat by now no matter what you did.
