Sparkling water without the shaking?

[mmesford]

I have a nice simple system. I store tap water in a plastic 2 litre bottle in the fridge. When we run low on sparkling water I connect a CO2 tank, through a regulator, at 30psi, to the plastic bottle and shake it for 60 seconds. I then decant it into two glass Gerosteiner bottles. This works fine. But it seems like we always run out when I’m in a hurry, or my shoulder hurts, or I’m tired, or some other lame excuse. We drink a lot of sparkling water so I have to make it almost daily. I just can’t help but wonder how SodaStream makes sparkling water without shaking. Is there some special adapter or cap that somehow injects the CO2 in a way that carbonates more efficiently? Is there some way to replicate that in my system? Thoughts?

two carbing caps? and some sort of quick cabr to have the water flow back into the first 2 liter as the pressure rises? kinda like easy shaking really....not sure just tossing something out...

Sounds mor complicated than a SodaStream. How do they do it? Also, what’s a carbine cap? What’s a carb?

What’s a carb?

but you'd have to use two 2 liter bottles i think to get the flow, because they don't make 2 liter sanke two valve caps....i think that's the soda machines work?

Sorry, spellcheck. What’s a cab? What’s a sanke? I’m getting confused.
