I once had an ingenius little pump made specifically to replace the screw-on bottle cap. By pumping air into the empty space, the bottle was re-pressurized and the gas was kept from escaping. I haven't seen one of those since mine went missing and I was hoping to find a cheap way for multiple bottles. My fridge is full of a variety of flavours all openned and partiaIly consumed. With the party over, and company gone after the holidays, the "pop" will be flat before I can finish them. Recently I've tried to make soft drinks last longer in the fridge by squeezing the air out of the large openned (2 litre) plastic bottles. I reasoned that If the level of the carbonated soft drink inside comes up near the top where the original level was before it was opened, and as long as the cap was screwed back on tight, then the gas would have nowhere escape to. That theory doesn't seem to work as well as the old pump. Perhaps because the thin plastic in modern bottles blows back out? Any ideas?

Closing the lid with no air in the bottle is the worst thing you can do. The gas will escape to try and fill the bottle capacity because of the low partial pressure of CO2 in the empty space. I'm very interested in the pumps though...never knew they existed!

Probably not cost efficient but if you had access to dry ice you could drop a small piece in the bottle and tighten the cap. Too much though and it could cause the bottle to explode.

ONCE YOU OPEN THE SODA, TIGHTEN THE CAP BACK ON THE BOTTLE BUT DO NOT PUT IT IN THE FRIDGE. THIS WILL KEEP IT FROM GOING FLAT. TRY IT!!!

you keep the soda upside down in the fridge.i've just recently tried it and it works..now, i keep all my sodas upside down...the reason being is because there's air on top of the bottle and if you keep it upside down, the pressure for the soda is eliminated and thus keeping them fizz for a long time..

I think these are what you were talking about. Should work. I haven't used them before though
