Hey there kiddo! Have you ever seen a piece of wood that looks all black and burned on the outside? That's called charring!
Basically, charring happens when something (usually wood) gets heated up to really high temperatures. It gets so hot that it starts to turn black and become all crispy on the outside.
But why does this happen? Well, charring is actually a way to help protect that piece of wood from catching on fire and burning all the way through. The black and crispy outside layer kind of acts like a shield, and can help keep the fire from spreading any further.
Charring can also happen on other things, like food! Have you ever had a really crispy piece of toast? That's kind of like charring too.
So remember, charring is when something gets really hot and black and crispy on the outside, and it can help protect things from catching on fire!
