You can get a used ball lock/corny keg, a carbonation cap, a co2 cylinder, and a pressure regulator, and make it 5 gallons at a time if you want. No support for Israel involved :)

Bit pricy, the whole setup you need will probably run about $100-200 depending where you get it, but you can put damn near any liquid in it and make it carbonated if you want. Wine, juice, water, sugar water, flavored sugar water, milk if you feel bold (tho at that point just make kefir, that’s nice and bubbly), beer, liquor probably..

Actually I just looked at the price of a soda stream and this isn’t that pricy by comparison.. so there’s that.
