Pop Rocks were developed in 1956 by General Foods research scientist William A. Mitchell and introduced to the market in 1975. Tiny air pockets of carbonation (CO2) are released when melted in your mouth and has a mild "crackling" sensation and "popping" noise. Contrary to urban legend and playground lore, Pop Rocks are completely harmless and a whole lot of fun!
