Can you believe that making soda is very easy while at home itself? Crazy, right? You don't have to worry about the big ingredients because you can easily make soda at home with just a few simple ingredients which are available at everyone's place! Simply add one pound of dry ice to one gallon of water, stir, and you're done. The subsequent reaction produces vaporization, fog, and, yes, the type of carbonation required to produce carbonated water. Quick fact: In terms of mineral content, soda water is similar to sparkling water. The primary distinction between the two is that, unlike sparkling water, soda water is not naturally carbonated. When soda water is infused with minerals, it becomes carbonated.
