Mildly Interesting

I use a "Spärkel" carbonator. Instead of CO2 canisters, it uses packets of citric acid and baking soda to generate CO2 and uses a compressor to infuse the liquid.

Pros:

• You can either use their pre-measured packets if that's convenient for you, or do what I do and just buy a bulk amount of both the citric acid and baking soda.
• You can carbonate pretty much any liquid. Water, wine, flat soda, mixed drinks, you name it. The sodastream will explode and cause a huge mess if you try to carbonate anything besides water.
• They don't appear to be Israeli.

Cons:

• Because it uses a compressor, it needs to be plugged in to operate. It's pretty loud too!
• It takes longer than a sodastream. While a sodastream is almost instant, this will take 1-3 minutes depending on the level of carbonation you desire.
