Alka Seltzer

How did this discovery come about?
How did they discover that you could make something that fizzes in water?

It’s not hard. You combine a power that’s acidic with another that’s alkaline. When water is added, they produce carbon dioxide. The fizzing has little to do with the effectiveness of the medicine.

Actually, I beleve Alka Seltzer was predated by Bromo Seltzer, which was the same thing as a powder instead of a tablet.

Bromo Seltzer was invented in Baltimore in 1891.

There is evidently a Bromo-Seltzer Tower in Baltimore, in commemoration of this event.
