Using marbles is messy.

Well better than using flammable gasses in your house or messing with a Nitrogen tank. A wine saver might be the simplest option really- probably "good enough".

Since we're into explosives, let's not leave acetylene out of the possibilities. Just a tiny bit of that would increase the size of your apartment tremendously!

Touché!

What if you lost your marbles? I think that's a given, due to how certain non-inert gases have been brought up. One spark, and there go not only all your marbles, but their former "container" too.

...Decades ago, there was nitrogen in a can (still available for wine drinkers), but that's not in my budget, either for wine or my print bath, so I was just wondering about something better, since my darkroom time is a bit more spread out now. ...

Don't know how safe it is for wine but works fine for chems and varnishes it's a little spendy and the can doesn't last very long -

There are also other blanketing gasses in a can that are not nitrogen, I don't know how compatible they would be for photo chems, I use it for
urethane rubbers and resins - https://polytek.com/products/polypurge-dry-aerosol-gas

Indeed.

On my budget, holding my breath wins, hands-down. As for the $12 for Bloxygen, as I usually remark only regarding items or services costing above $1,000, "That's a good bottle of wine!"

I suggest not bothering with any of this, including using your breath, which will do virtually nothing. Use some smaller bottles, or simply use a developer with better keeping properties.

I bought a box of 500 ml brown bottles from the Formulary, mix up 5000 ml of Xtol type developer on a stirrer, fill the ten bottles up evenly then if there is any space at the top I add distilled water to each bottle. It’s never more than 10 or 15 ml in each bottle and the solution lasted for way longer than it should with no degradation.

Nonsense! Just buy some glass marbles.

I was kidding, it would work though.
