Kelloggs has claimed that Rice Krispies 'snap, crackle and pop' since the cereal was first marketed in the UK in 1932. According to the original radio adverts the 'snap, crack and pop' sound was 'your food talking' – but science has a much more mundane explanation.
To make Rice Krispies, rice kernels (or grains) are cooked, dried and toasted. This causes the kernals to rise and expand so that the walls of the kernel become very thin and delicate. The milk being poured on the cereal makes these thin walls suddenly fracture and collapse – resulting in the famous 'snap, crackle and pop' noise.
However it's only 'snap, crackle and pop' if you live in the English speaking world. If you live in Sweden you will hear them 'piff, paff and puff' when you pour the milk. In Mexico they 'pim, pum, pam', in France 'cric, crac, croc' and in Germany they 'knisper, knasper, knusper'!
