Rice Krispies (called Rice Bubbles in Australia) is a brand of breakfast cereal that has been produced by Kellogg’s since 1928. They are made of rice grain which is cooked, dried and toasted. These kernels bubble and rise in a manner which forms very thin walls. When the cereal is exposed to milk or juices, these walls tend to collapse suddenly, creating the famous “Snap, crackle and pop” sounds. This is in contrast to puffed rice, which was introduced in 1904.
Snap, Crackle and Pop! are the cartoon mascots of Kellogg’s breakfast cereal Rice Krispies (Rice Bubbles in Australia).
