How to make soda flat ... quickly?

Is there a way to make soda go flat quickly?

Other than just leaving the can or bottle open and letting the carbonation fizzle out on its own, is there a way to speed up the process?

I know I can empty out about a 1/3 of a 2 liter bottle, re-cap it, shake vigorously, open and let out the carbonation. This will speed up the process somewhat.

But with a can, that's not really possible.

Any tricks out there? Thanks.

  1. heat will interfere with a liquid's ability to hold gas, so you could heat it up.

    1. May I ask as to why you need it to go flat? I agree with arifa, I actually boil coke with ginger as a homeopathic remedy.

        I am a long-distance runner and cyclist (currently training for a triatholon), and instead of Gatorade and other energy drinks, I prefer Coke because it has the sugar and the caffeine without the high cost and the funky taste and after-taste of those energy drinks.

        But because soda is carbonated, it is a bit difficult to down. Having it flat is much easier to swallow and easier on the stomach as well.

          You know that coke won't hydrate you properly, right? The corn syrup and caffeine can actually cause dehydration. Sports drinks have electrolytes and such that are specifically designed for athletes. Have you tried the Fitness Waters? They don't have that aftertaste.

          1. re: mojoeater

            I dilute the (flat) Coke. But, yes, I did not know that caffeine is a diuretic.

            That said, you really don't want to know what I do when I'm about to bonk ... flat Mountain Dew with a Twinkie.

            Cheers.

            1. re: mojoeater

              The idea that Coke causes dehydration is a myth. While corn syrup and caffeine are diuretics, the amount of water in the Coke overcomes the effect of the diuretic components.

              This doesn't help w/ the defizzing but have you tried vitamin water by glaceau? I can't drink the other sports drinks but I like it. They have different types that are supposed to be for different things but they've all been fine for me when I do anything long distance (meaning 1 1/2 hours or longer).

              http://www.bevnet.com/reviews/glaceau...

              It doesn't have caffeine, but you could take an exedrin w/ caffeine. Also, believe it or not, Mountain Dew was formulated for that purpose (extra energy for exercise--who thought to add carbonation to it?? Or, at least,that's what I learned in marketing class) and it has more caffeine than coke. What if you pour the coke into a water bottle in your belt and ran/biked with it? That would deflate it (don't fill it too high). If you start w/ it partially defizzed, by opening it earlier, then it wouldn't explode.

              1. re: chowser

                Thanks, but I find the Vitamin Water and Fitness Water stuff better for AFTER a long training session, and not very good during a long run or bike ride.

                The Coke (or Mountain Dew) has lots of sugar and caffeine which provides a nice immediate adrenaline rush (fake as it is ...).

                Cheers.

                1. re: ipsedixit

                  They don't provide as much sugar as the other drinks but maybe because I'm a small person that they've provided enough energy for me thus far. We'll see how it works when my runs get longer than 2+ hours. I'll probably eat at that point. I'm thinking the sugar and all from Coke and Mountain Dew would make my stomach seize up. I'm still working on gu, but it's just not chowhoundy no matter what flavor I've tried!

                  1. re: chowser

                    Yeah, I find all varieties of GU disgusting. Every time I see one of those, I think I should be up in the space shuttle or down in a submarine.

                  2. re: ipsedixit

                    Keep the soda warm and stir it around gently. This will encourage the CO2 to escape more rapidly. I'd stay away from the caffeine--you don't want to lose water. You may want to try that version of Coke that does not have caffeine.

                    You can also buy gels, but most people I've heard from don't like the taste. I used to eat breakfast cereal bars on my longer rides to prevent bonking. I also used to drink diluted Gatorade; I bought the powdered form because it was a whole lot cheaper than buying the bottles: about $4 for enough powder for 10 quarts.

                      My husband, a diabetic, carries glucose tubes that he says tastes/feels like cake icing.

                      And yea, I had the same question about "bonk" that purple goddess did! :-P

                2. re: ipsedixit

                  Fellow long distance runner and cyclist here... Props to ya! (Which one you training for?)

                  Personally I'm a water fan, but that said, do you take it in a sports bottle and have time to let it defizz the night before, or are you trying to get it to defizz rapidly when you purchase it along a ride or run...?

                  Have you experimented with Hawaiian Punch (love the fruit flavor) and no carbonation to contend with. Snapple flavored Iced Teas are also caffeine and sugar. I know you want to defizz Coke, but just thought these might also get you to the same place, if you don't mind their flavors, though I'm sure if you're like me, you've pondered everything...

                  1. re: ipsedixit

                    I'm training for the Nike marathon in San Francisco. Thinking of going for a tri in a couple of years. I don't care for the Gu or any other gels as well. I do like the Shot Blocks, good to suck on. I also use Cytomax. I don't like many of the sports drink, but can get just the right flavor when I mix it myself.

                    1. re: justagthing

                      I've tried those electrolyte jelly belly. It's too hard to chew and run and breathe at the same time for me but I've heard the Shot Blocks are good so I just bought a pack. Sometimes I'll take a few bites of a Luna bar (probably not ideal but I like how it tastes) and walk. Has anyone tried real food that works? I was thinking of trying something like bread and honey. There must be something that tastes good that gives you quick energy (I know it's not that much of a concern to most people who are running...). I wonder if there is something I can bake. BTW, we'll be doing marathons about the same time--I'm doing the marine corp in Oct.

                      1. re: chowser

                        It's funny, but during an actual race or marathon I can actually fight through a big energy drop.

                        It's during the training runs of 20k or more (or a century ride) when my body just screams for some simple carbs and lots of sugar. I don't like to eat anything that requires actual chewing, which is why my default has always been a Twinkie and some flat Mountain Dew or Coke.

                        1. re: ipsedixit

                          Twinkies and coke! That's so far out of the gu and gatorade rhelm. I don't do long distances yet so we'll see how it goes w/ the marathon. I'll keep twinkies in mind...maybe... I'm not sure if I could eat one.

                          1. re: ipsedixit

                            As a runner, I find that caffiene decreases output. Mountain dew, however, is way out there in termsof caffiene.

                            Alton Brown did a show where he made homemade power bars. I did a version of the crispy bar and it was good:

                            1. re: mojoeater

                              Thanks--I'll give those a try. They look like they'd be good for what they are but not the same as, say cheesecake. I just bought some Costco granola--full of whole grains, honey, dried fruit, nuts and it's pretty good. A little chewy, though, while running.

                    2. Pouring soda over ice helps unless you don't want it diluted. Pouring soda over anything bumpy and lumpy will help; it gives the carbonation more contact points on which to burst.

                      1. Take a warm can of soda and pour over ice - instant flat soda. I try to avoid this situation at all costs.

                        1. When we were little, and sick, my Nanny would serve us flat coke or gingerale (depending on "sickness"). She would put it in a glass and stir with a spoon for a few minutes, changing directions once or twice. It was also at room temperature.
