In the 17th century (1767), Joseph Priestly and William Painter created the first intentional carbonated soda water by inciting a chemical reaction between sulfur and chalk. The resulting carbon dioxide gas was infused into water, which he then drank (carbonated mineral water). This is the first known occurrence of someone drinking soda water and is thus the very start of the soda pop's long journey. That was the time when was soda invented.
