Hey buddy, have you ever heard of a tinderbox? Well, it's a little box that people used in the olden days to help start a fire.
You see, back then, people had to start fires themselves and it wasn't easy because they didn't always have matches or lighters like we do today. So they would use the tinderbox to help them.
Inside the tinderbox, there are a few things that can help start a fire. There's usually some dry material like leaves, straw, or even some shaved wood. There's also some flint and steel. When you hit the flint and steel together, it creates a spark.
If you take that spark and put it onto the dry material in the tinderbox, it will catch fire. Then you can use that fire to start a bigger fire.
Isn't that cool? The tinderbox helped people survive and stay warm, even when they didn't have modern technology like we have today.
