Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

LPT: go get

  • a real CO~2~ cylinder with a CGA 320 valve (the 10lb size is plenty)
  • a CGA-320 CO~2~ regulator
  • some 1/4" ID reinforced PVC tubing
  • a carbonation cap + 1/4" barb ball lock disconnect (mentioned together because they're often sold as a set), and
  • a plain old empty 2-liter soda bottle.

That's everything you need to carbonate soda yourself without some proprietary bullshit device.

(I found the best price for the gas cylinder from a local company that resupplies restaurants etc. with soda dispensers, which is convenient because they can also refill it for you. The rest of the stuff can be found easily enough from Amazon or whatnot. I wouldn't buy the cylinder from Amazon unless I wanted aluminum instead of steel, for no good reason.)

Works if you have space to put a 10lb CO2 cylinder

There's also smaller 5# tanks

You have to make sure whatever you use is food grade. A paintball refill wouldn't have to be and could contain weird oils you wouldn't want to ingest.

Even better: get a soda keg, fill with water and charge with CO2. Seltzer on tap!

Better, but more expensive and space-consuming, especially if you want to store the keg in a fridge. One day I'll do it right (including storing the keg(s) in a mini-fridge in which I've cut a hole to route a line to a dispenser), but that day is not today. : (
