A pencil writes smoothly because it doesn’t dry up like a marker does. Inside the pencil is graphite, which feels like powder. When you write, only a tiny bit of graphite rubs off onto the paper, not all of it at once! That’s why your pencil keeps working even after hours of writing.
Why It Doesn’t Dry Up
Think of a pencil as having layers of powder inside. Every time you draw or write, just a little bit of that powder comes out, like when you shake a bag of sugar and only a few grains fall out at once. That’s why it takes so long for the pencil to run out.
Examples
- A pencil works like shaking a bag of sugar, only a little falls out each time you write.
- If you use a pencil to draw all day, it won’t run out until the end of the year!
- Even after writing for hours, your pencil still has plenty left inside.
