Rice Krispies^TM Crackle!

If you have some Rice Krispies^TM or other crisped rice cereal at home, you can listen to what we're calling crackling noise. Get a bowl, fill it with the cereal, and pour on milk.

LISTEN CAREFULLY to the crackling noise. It's quiet, but if you put your ear right up next to the cereal (don't get your hair into the milk!) you'll hear lots of tiny sounds.

Just like popcorn popping, the sounds come at random times. Sometimes a lot will happen at once, and sometimes there will be quiet periods.

You'll notice that some of the sounds are louder, and some are really, really quiet. The sounds come with random sizes. Crackling noise happens when lots of short sounds come at random times, with some sounds much louder than other sounds.
