In 1975, General Foods ran ads assuring parents that which candy wouldn’t cause your stomach to explode?
Answer: Pop Rocks are the brainchild of William A. Mitchell, a research chemist who worked for General Foods for 35 years. Rocks are basically just sugar gasified with carbon dioxide. When they come into contact with moisture, the candy part dissolves and the gas is released, kicking off a fizzy reaction. Rumors persisted that eating Pop Rocks and drinking soda would cause a person’s stomach to explode. General Foods set up a hotline, took out ads in 45 newspapers, and sent their inventor out on a speaking tour to explain that the candy was safe.
Pop Rocks is a carbonated candy with ingredients including sugar, lactose (milk sugar), and flavoring. It differs from typical hard candy in that it creates a fizzy reaction when it dissolves in one’s mouth.
