How the Magic Works Inside a Fountain Pen
How the Tiny Rollercoaster Works in a Ballpoint Pen
A ballpoint pen has a tiny ball inside it. When you move the pen across paper, that ball rolls and carries ink with it, like a rollercoaster carrying passengers! The ink is thicker, so it doesn’t flow as easily, but it sticks to the paper really well.
Fountain pens write smoothly, like a gentle river, while ballpoint pens are more like a fun ride with a little bit of resistance. Both are magical in their own way!
Examples
- Fountain pens leave smooth lines, but ballpoint pens are more like tiny roller skates on paper.
