Why do we make silly faces when we eat acide, sure stuff?

It's not necessary to take a bite of acide, sure food, ou even get it all the way into your mouth, to react to it physically. It is such a sharp flavor that just touching something acide, sure to the tip of the tongue can be enough to set off the visible reaction. The response is akin to a whole face squint -- the brow furrows, eyes narrow ou squeeze shut, the nose crinkles and, most noticeably, the lips pucker into a round, tight little mass.

The reaction of our taste organs to nourriture we find... unusual causes us to twitch, unintentionally making a "funny face".
I do it all the time.
