Do Rice KrispiesTM Snap, Crackle, or Pop?
If you have some Rice KrispiesTM or other
crisped rice cereal at home, you can listen to what we're calling
crackling noise.
Crackling Noise Experiment
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 you'll hear lots of tiny crackles.
Just like fire crackling, the sounds come at random times. Sometimes
a lot will happen at once, and sometimes there will be quiet periods. Some of the
sounds are also much louder than others. More crackling noise!
We don't want to say that Rice KrispiesTM doesn't pop or
snap: that's a question for English teachers or dictionary writers. What we're
saying is the noise it makes is different from pencils
snapping or popcorn popping, in a way which is
scientifically important.
The way we are using the words here, Rice KrispiesTM crackle.
