Rice Krispies (also known as Rice Bubbles in Australia and New Zealand) is a breakfast cereal marketed by Kellogg's in 1927 and released to the public in 1928. Rice Krispies are made of crisped rice (rice and sugar paste that is formed into rice shapes or "berries", cooked, dried and toasted), and expand forming very thin and hollowed out walls that are crunchy and crisp. When milk is added to the cereal the walls tend to collapse, creating the "Snap, crackle and pop" sounds.

Rice Krispies cereal has a long advertising history, with the elf cartoon characters Snap, Crackle and Pop touting the brand. In 1963, The Rolling Stones recorded a short song for a Rice Krispies television advertisement.
