I bought a seltzer maker a while back. It uses these 8gram Co2 cartridges to make soda. I used to put the empty ones in the recycle bin until I realized that they mat be of some use on my layout. But I’m at a loss as to what to do with them. Anyone have any ideas? And no...not to put them there🙄. Thanks

Create a conical seat to stand them upright, add pipeing, paint white, med green, or Leave as raw stainless, maybe give it a fence, and you have chemical storage tanks for out back at an industrial based business. Which end goes up and the tanks finish, is really a choice based on what's inside it as much as your preference.

It seems to me there was a Lionel, AF or Marx flatcar that used 2 CO² tanks like that; inline & on stands as a load.

I'd recycle them and move on.  

Unless my first glance at something like this sends a creative message....'Hey! I could make that into a _______ for the layout!!!'....collecting/saving things like this is what creates the junk piles in the house. 

You know those little coffee creamer cups with the peel-off tops?......they make dandy trash cans in larger scales (not my idea, someone else's.)  After saving just short of a bazillion of these, it suddenly dawned on me that they were pure trash themselves!.....and so they found a new home in the recycling container placed at the end of the driveway one day.

So, the other thing I've learned in life....if I received that first-glance creative message above...is that if I don't actually create that gizmo within a week or two, it will become this nuisance thingy that clutters my life....to the point that years later I'll see it on/under the workbench and say...."What the %#@$& am I keeping this thing for??!!".....inspiration long gone.  THEN it ends up where it probably should've ended up long ago!

I know, that's not what you wanted to hear re these spent cartridges...  Sooooo....

You could cut them in half....pitch the narrow ends.  Then paint the domed ends bright yellow, put some faces/hair fuzz on them, pack them into a gondola or behind the opening door of a boxcar, and....Voila!....MINIONS!!

Well, I might find some tubing of the same diameter and cut and splice them into longer tubes to make a helium car like this

or cut and splice them into smaller cylinders and make something like this Chlorine tank car

Tichy makes decals in S for both cars and the car bodies would be easy to construct from Plastruct structural shapes and sheet abs.

I have been meaning to make a chlorine tank car ever since I saw an article in the early 1970's about constructing one in a Model Railroader "dollar car" book (long out of print). Maybe I will get off my butt and do it.

They look a bit like the dummy tanks on a Lionel track cleaner but those tanks had flat bottoms. Never the less if you have a track cleaner misssing it's tanks the CO2 tanks would make a good substitute.  j
