Keep the fizz in and the insects out with these Bottle Caps


Once you’ve opened those old-fashioned soda bottles or a beer bottle, there’s not usually a good way to keep a cover on your drink while you’re finishing it.  These Linden Sweden Bottle Caps will snap on the open bottle and keep the fizz in.  They’re also a great way to keep insects out of the drink at picnics, and to keep unwanted things out of your beer or soda while you’re at the bar or a party.  A pack of 10 Linden Sweden Bottle Caps in assorted colors is $6.57 from Amazon; Prime shipping is available.

    My understanding is that once opened…..there is no way to “keep the fizz in” unless you re-pressurize the carbonated liquid with carbon-dioxide. Even those pump gadgets will not work because it is pumping in an air mixture containing 21% oxygen.

    Jimmy, I wouldn’t think these would be suitable for anything other than keeping your drink covered while you finish it. It might slow down the loss of carbonation, but it’s not going to keep the contents bubbly for days after opening. Each time you remove the lid, a bit more of the carbonation gases will be escaping, so you probably shouldn’t take all day to drink it.

    It’s less a matter of “keeping the fizz in” and more a matter of “slowing the loss of fizz”. A good, sealed cap will slow the loss. The pressurized caps will slow the loss more.

    I’m lucky in that I have access to dry ice. I can re carbonate soda at my whim — or carbonate other drinks. Ever have fizzy milk? Yeah… it’s about as nasty as it sounds.

    Drop a bit in the liquid. As the dry ice sublimates it will infuse the liquid with co2. *OR* Put a tiny bit in a bottle and close it, it will infuse more efficiently — just be careful as it CAN go boom. I just leave the cap open enough so that you can hear the gas escape when the pressure gets too high.

      @jhon very cool. I always thought dry ice was poisonous… shows how much I know (or in this case don’t know).

    “very cool”. Heh. I see what you did there…
