The reason a softdrink becomes flat is because after you've opened the bottle and drunk half of it, the container is not under pressure anymore so the dissolved co2 leeches out of solution, right? But if you had a lid with a little pump on it, like a tiny bike pump for example, or a balloon pump, and pumped it back up to an adequate pressure before you put it back in the fridge, would it prevent the co2 from coming out of the solution? or would it need to be carbon dioxide in the container, not just air?

If you keep an unopened bottle of pop for a long time, say a year or so, when you open it you will find that it has gone a little flat. I assume this is because of an escape of the pressurised gases, so the top seal must leak to some degree. Perhaps because the seal degrades after a while.

Re pressurisers are already available,


I found this one on eBay. We used to have one like this, but found that the bottles never really lasted long enough to warrent it.

Silly arse! I mean the contents of the bottle were consumed so quick it wasn't worth the p*****g around with the pump.

Well you knew this, I think you were just FOGGING me.

FOGGING? I am not old enough to remember what this means? Actually, I haven't been around long enough. Why did you do p*****g, I presume it is pumping?
