If you're a fan of bubbly waters but never knew the difference between the types, here's an explanation. The difference between club soda and seltzer water is how the bubbles got there. Club soda has a small amount of sodium bicarbonate, so it's a little higher in sodium. Seltzer's bubbles are added by injecting water with carbon dioxide. So it usually has no sodium (and no calories, either).
