What makes Rice Krispies snap, crackle and pop?

The sound track. Programmed into each of those little rice thingies.

Did you really mean this to be a general question? How unfortunate! I wonder if it would be legal to copy a question in the social section, especially ones like this!

It probably has something to do with milk entering spaces in the cereal and then they expand and break with those sounds.

Now wasn’t that exceedingly boring?

@wundayatta I did mean it as a general question. I wanted the real answer.

A Rice Krispie behaves like a piece of glass. If you hit it hard, it’ll break into a puzzle of a million pieces.

The high temperature at which the cereal’s cooked creates extremely strong bonds that hold the rice’s starch molecules together. The strong bonds make the rice act like glass.

During the cooking process, each piece of rice expands and a network of air-filled caves and tunnels form inside.

When you pour milk into your breakfast bowl, the cereal absorbs the milk. As milk flows into the crispy kernel, the liquid puts pressure on the air inside and pushes it around.

The air shoves against each pocket’s walls until they shatter, forcing out a snap, or a crackle, or, as you, know, sometimes a pop.

You can also see tiny air bubbles escaping to the surface.

@Cruiser Thank you! :D

The same thing on a micro scale that happens to torpedoed ships that sink during submarine attacks: chambers filling with liquid, bulkheads blowing out, and more chambers filling, etc., as the vessel sinks. Submariners like the ‘snap, crackle, pop’ sound, as it means they have been successful. Destroyer captains, on the other hand…
