Why Do Sour Foods Make Us Pucker?

What Crafty Clover says in this video

Intro

Hey there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do sour foods make us pucker?

The Big Idea

Sour foods, like lemons, contain acid. Your tongue senses the acid, and your face reacts fast. That is why you pucker. It is a fast way to get attention.

Acid Hits the Tongue

Step one: acid hits the tongue. A bite of lemon puts acid on your tongue. Acid has a sharp, tangy taste. Sour foods include lemons, limes, and green apples.

Sour Sensors Fire

Step two: sour sensors fire. Special sensors on your tongue notice acid. They send a signal to your brain. Sour sensors are sometimes called acid sensors.

Cheeks and Lips Squeeze

Step three: your cheeks and lips squeeze. Your brain sends a quick message to the muscles in your face. It all happens automatically. Your mouth waters a lot, too, to wash the acid away.

A Closer Look

Let's take a closer look at the pucker. The tongue senses the acid. The face muscles squeeze your cheeks and lips. And your mouth ends up in a tiny round o shape, which is the pucker. Each step takes just a blink.

Quick Facts

Quick facts! A pucker is a reflex, not a choice. Some scientists think sour warns us about unripe or spoiled food. Many kids love sour candy anyway. Brush your teeth, because acid can be hard on them. Sour is one of the five basic tastes.

Think Like a Scientist

Now, think like a scientist! Ask a grown-up for a tiny bit of lemon. Stand in front of a mirror. Taste the lemon, and watch your face. Which parts of your face move?
