The cereal is trying to tell you something! "Please don't drown me!" But because they don't speak English, and only speak Poppish, we don't listen! I'm taking a course in Poppish so I'll be able to understand my cereal!

Scientists are still doing the research. Just hang in there, Boop. LOL

Unlike the compact, hard walls of an uncooked rice kernel, the walls of puffed rice are stretched very thin, making each kernel quite fragile. When cold milk is poured on, the shock causes the walls to crack like a thin glass crystal. As the milk is (unevenly) absorbed by the puffed rice grains, the snapping, crackling and popping sounds come from the fracturing of the walls and the escape of air bubbles trapped inside the kernels.

You know me, science first then humor.
There's a little known reason as to why Rice Krispies make that supposed "Snap, Crackle and Pop" sound when you pour on the milk. Quite simply, it's because they're desperately pleading for their lives. You see, the fact of the matter is, this so-called popular breakfast cereal is actually a living organism. Scientifically known as Ricetisis Krispithecia, the Krisp-bug as they are more commonly called, is a miniscule, oval, hard-shelled beige insect that's unfortunately not used to being wet. (Although they are quite buoyant.) So, if you listen very closely, what you're actually hearing are their urgent, panicky cries for help: "Hey, how did I get in here? Help, I'm drowning! Help! I'm not a very strong swimmer. Someone please help me!!" ... I find that by simply submerging them under the milk for a few seconds with my spoon seems to shut them right up... Hey, let me tell you, with a little sprinkling of sugar, their soggy, bloated, lifeless bodies sure makes for some tasty eatin'.

Richard is right and the "snap, crackle, pop" sound of it makes our little kiddies want to eat it. That makes us happy.

It just does!

I guess there is some air in them and it sets free when they crack under the pressure of milk.

Crackle and Pop is when the milk reacts with the Crispies and the 'Crispie' piece collapse making the famous sound.

While Rice Krispies may be the noisiest cereal, other puffed cereals may also snap, crackle and pop when doused with ice-cold milk. Just as corn is popped into popcorn, rice, wheat, and other grains can be puffed up into fluffier versions of themselves. In the case of puffed rice, cereal makers oven-toast the rice, which has been conditioned with water. As the water turns to steam, rice kernels puff out like microwaved popcorn.

Meanwhile, if you pick up your spoon to eat your talking cereal and notice a few white spots on your fingernails, don’t panic. Some cultures see the white spots as a good luck sign, and even call them fortune or gift spots. There’s also the old idea that someone with a white spot on a fingernail is in love, or that the number of white spots equals the number of “sweethearts” a girl has. In an Alice Hoffman novel, a white spot appeared on a character’s fingernail each time he lied, a telltale sign like Pinocchio’s growing nose.
