Amazon.com Review

Unless you're prone to malaria, it's a decent bet you won't finish a bottle of quinine-laced tonic water at one sitting--likewise, that bottle of sugar- and caffeine-free Coca-Cola that was brought to a Pepsi Lovers' picnic. And if there's anything sadder than a fizzless, half-filled bottle of cream soda taking up refrigerator space, please keep it to yourself. How to preserve the fizz in that 1-, 1.5-, or 2-liter bottle that wasn't finished? Jokari has created a solution with the Fizz-Keeper pump cap, a simple device just over 3 inches tall that screws onto the bottle's neck, replacing the existing cap. By repeatedly raising and lowering the simple piston until the sides of the plastic bottle (it's not for use with glass bottles) don't compress, you've effectively created an airtight seal and equalized the internal pressure. As the name "Fizz-Keeper" suggests, it's all in an effort to ensure that Saturday's soda makes a gin and tonic effervescently refreshing, even on a Tuesday. --Tony Mason

Product Description

Nothing is worse than sitting down with your ice cold cola, only to discover that is flat. Using Jokari's fizz keeper pump, you can re-pressurize your two liter bottles so that they retain their carbonation. Simply press down on the easy to use hand pump, and make sure the seal is tight. With pumping, the soda's elongated life can now last for weeks.

5.0 out of 5 stars The Fizz Keeper Works! Please Read This, November 13, 2007

Sorry Palmer (and the American Chemical Society) I have used the Fizz Keeper for more than 5 years and I KNOW it works! The only time any of mine have ever failed is when they have cracked around the top rim or when I didn't pump them enough times. I have one pump which is still working after 5 years. With care, I am certain your Fizz Keeper will last as long.

Here is the best way to use them.

1. Don't put them on a bottle until you have drank enough so that the pump isn't sitting in the drink. The sugars in the soda can cause the pump to stick.

2. As much as possible, don't shake or get the pump drenched in soda.

3. As soon as you're done pouring your drink put the pump back on the bottle, pump the pressure back up and stick it back in the fridge.

4. As the amount of soda in the bottle drops, you will have to pump the Fizz Keeper more times.

Here's how many times I pump it: Top 1/3 10 to 12 times. 50% gone ... 18 to 20 times. 1/3 or less left, 30 times. If you don't keep enough air pressure in the bottle, the carbonation will come out of the soda as the level drops and fill the vacuum left in the bottle. I pump the Fizz Keeper until I find it hard to squeeze the bottle in at its sides.

Don't shake the bottle as you pump. This agitates the carbonation and causes it to leave the liquid. Place the bottle on something solid, like a counter, and then start pumping.

5. As you pump, don't bang your Fizz Keeper. If it's making a clapping sound as you pump. You are pumping it too hard. Don't try and draw a full stroke on it, partial (3/4 strokes) will allow it to last as long as possible. Once it starts to crack around the top rim it's done for and you'll have buy a new one.

6. Remove and rinse it with water after the bottle is empty.

I hope the above helps all who are considering buying this little marvel.

I have purchased and used almost all of the various soda keepers on the market and this is the only one I can recommend. You are gonna love it and use it often!

I thought I would add the following. Though Kurt Greske is correct about air being more soluable in water than the carbonation. In a "closed system" like a plastic bottle that process will take some time to occur. Unlike your lungs (which are an open system) the carbonation has to go somewhere; hence the process doesn't occur immediately. It takes some time. As long as you finish the bottle within a couple of weeks I doubt you will even notice what loss does occur. After all, I doubt any of us would want to drink from a soda bottle that was opened two months ago. All I ask the Fizz Keeper to do is extend the life of the soda a reasonable length of time. For me, that's two weeks, maybe less.

5.0 out of 5 stars Great Idea that really works!, May 4, 2004

Wow! It didn't go flat on me. This is one of those simple ideas that should have been thought of years ago when they first invented plastic soda bottles. Screw it on and pump it up a little. Your open bottle of soda will now last up to a week or more. Made right, they last a long time too. Have fun!

5.0 out of 5 stars It works every time for us, July 6, 2006

We LOVE this item -- our soda doesn't go flat, even if there is just a little soda left. Perhaps the other reviewer didn't pump it enough times? We've used this for over 5 years now, without problem -- except they're so HARD to find!

It seems to work by putting enough air pressure into the bottle so the carbonation doesn't have 'room' to pop and go flat. Please restock these!

UPDATE 12/5/2011: We still love these. They still work for us. We are still using the same ones, although one did break it seal and stop working after 4 years of daily use. I don't know how they work; I just know they do.
