Origin of Pop

Soda was patented in the United States in 1809. It created bubbles by mixing water, bicarbonate of soda and an acid to make what was called "soda water."

The word "pop" was added in the mid-nineteenth century and supposedly reflects the popping sound that is made when a carbonated beverage is opened.

The original sparkling waters were naturally bubbly spring waters.  The most notable of these may be Seltzer water from Germany. Generic carbonated water, particularly the kind made at home with what is now referred to as a soda siphon, became commonly known as Seltzer even though it had no connection to the German origins.

Inventors from several countries tried to imitate natural sparkling waters by adding bubbles to still water. Various techniques were invented using different chemical and mechanical methods.

Since then, the simpler technique of combining water with pressurized carbon dioxide gas has come to predominate the commercial market. Despite the fact that sodium bicarbonate is no longer used in their manufacture, the term "soda" has remained attached to the name for drinks made from carbonated water.
