Black's ice-cream soda, which contained whipped egg whites, sugar, lime juice, lemons, citric acid, flavoring, and bicarbonate of soda, was a concentrated syrup that could be reconstituted into an effervescent beverage by adding ordinary ice water. In the United States, cream soda is often vanilla-flavored and is either clear or colored a light golden brown in appearance; but red, pink, orange, and blue are also relatively common color variants. In addition, in some places in the U.S. where the drink is made on location, especially
Carbonated drink Carbonated drink Carbonated drinks are beverages that contain dissolved carbon dioxide. The dissolution of CO in a liquid, gives rise to "fizz" or "effervescence". The process usually involves carbon dioxide under high pressure. When the pressure is removed, the carbon dioxide is released from the solution as small bubbles, which causes the solution to become effervescent, or fizzy. A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. Carbon dioxide is only weakly soluble in water, therefore it separates into a gas when the pressure is released. Carbonated beverages are prepared by mixing flavored syrup
