A firepit is like a big plate where you can make a fire and everyone can gather around it. It's usually made of metal or brick and is put outside in your backyard or on your patio. You can burn wood in it and roast marshmallows or hot dogs over the fire.
You have to be careful not to get too close to the fire because it's hot and can burn you. And you should never try to start a fire in it by yourself. An adult should always help you with lighting the fire and making sure it's safe.
Firepits are great for spending time with your friends and family, and enjoying the warmth of the fire on a chilly night. Just remember to be safe and have fun!
