Incense is like a special kind of smelly stuff that people burn to make a room or a place smell nice. It's kind of like a candle, but instead of giving off light, it gives off a smell.
People have been using incense for a very long time, maybe even thousands of years! People used to burn incense for religious ceremonies or to keep bugs away. But nowadays, people might use it just because it smells good.
To use incense, you light one end of a stick or a cone and let it burn for a little bit. Then, you blow out the flame and you'll see smoke coming out of it. That's when it starts to smell really good! You can put it in a special holder or just hold the stick as it burns.
Some kinds of incense smell like flowers, and some smell like spices. You can find all sorts of different scents at a store that sells incense.
It's important to be careful when using incense, because you don't want to accidentally start a fire or breathe in too much smoke. But if you do it right, incense can be a great way to make your room smell amazing!
