What is sniff?

"Sniff is when you use your nose to find out what something smells like."

Imagine you're playing with your favorite toy, and it starts to smell weird, maybe like wet socks or burnt popcorn. You don’t know what happened, so you sniff it, which means you bring your nose close and breathe in the smell.

When you sniff something, you’re helping your brain figure out what’s around you. Your nose has special sensors called smell receptors, which catch tiny bits of air that carry the scent. These sensors send messages to your brain, and boom, you know what the thing smells like!

You do this all the time, like when you sniff a cookie before you eat it or when you sniff the air outside to see if it's raining soon.

Just like how tasting food tells you what it is, sniffing helps you know what things are, even if you can't see them. It's like having a superpower that lets you smell your way through the day!
