Why do some foods squeak when I chew them?

[Nippless]

Mushrooms, grapes, some kinds of peanuts and crunchy peanut butter are a few. What is it that’s squeaking?

[kk_fusion]

Friction, I suppose. Of the tire-against-road variety, though on a smaller scale of course.

Thanks for that Sunday funny.

Their souls are escaping.

You’re squeezing out air pockets.

Yeah, same reason anything under grinding stress squeaks: lack of proper lubrication at the point of the sheer.

And no, I’m not JUST kidding with that. It’s the real answer.

Halloumi is notable for making one’s teeth squeak.
