I’ve often wondered if I could prepare my own carbonated water. I could save on buying commercial bottled water and also help the environment, especially by not buying water in plastic bottles.
A company called Sodastream has developed a home gadget that will carbonate tap water which you can then serve or store in bottles. It’s the size of most coffee makers or food processors. You can even add flavor to the carbonated water such as lemon lime, orange, etc.
Oddly enough, the bottle provided by the company is plastic! I think a much better idea would be to provide an aluminum bottle. That would make it a truly green product end to end.
