SodaStream question - What happens if you re-carbonate?

Yes it seems the pure water can be moved around with lots of CO2 in it,
but if there is flavour in there, its all bubbly.

The flavour, eg sugar seems to make foam, and I say eg sugar because the diet coke foams up without sugar !

I’ve used both mods. I started out with the paintball tank mod. We drink a lot of soda, so I’d refill three 24 oz tanks once a month. But more often than not, Dick’s would be out of CO2 when I went in, which got really old. Apparently their business model is to wait until they are completely out before ordering more. But anyway…

I finally got sick of it and ordered a Freedom One mod. This setup is awesome. A 10 lb tank lasts about three months, and a local home brewing company exchanges them for $15. And I’m in and out in less than two minutes, rather than waiting around at Dick’s while they slowly fill up paintball tanks.
