How Were "Pop Rocks" Named?

From Wikipedia:

Pop Rocks is a carbonated candy with ingredients including sugar, lactose (milk sugar), corn syrup, and flavoring. The idea of the product was patented by General Foods research chemist William A. Mitchell in 1956. The Pop Rocks candy was first offered to the public in 1975. Around 1983, General Foods stopped selling the candy; some would believe this was because of an urban legend. A few years after, in 1985 Kraft Foods bought the rights to the candy product and re-marketed it as Action Candy through a company called Carbonated Candy.

The candy is made by mixing its ingredients and heating them until they melt, then exposing the mixture to pressurized carbon dioxide gas and allowing it to cool, trapping the pressurized gas inside.

When placed in the mouth, coming into contact with saliva, the candy breaks and melts, releasing the carbon dioxide from the tiny 600 psi bubbles, resulting in a popping and sizzling sound and leaving a slight tingling sensation. The bubbles in the candy pieces can be viewed when aided by a magnifying glass.
