A fountain pen is like a tiny water balloon that never stops filling up. When you write, the ink flows from inside the pen to your paper because of a little air pocket that helps push it along. It’s like having a helper inside your pen who makes sure the ink keeps coming so you can draw or write without stopping.
The Magic Inside
Inside the pen is a special kind of ink that likes to flow. When you press down on the pen, the ink moves up and out through the tip to your paper, just like when you squeeze a bottle of juice and it comes pouring out.
Examples
- Writing a thank-you note with a blue pen feels like magic, no buttons or batteries needed.
- The ink moves through the pen just like juice moves out of a squeezed bottle.
