A ballpoint pen can last for years because it doesn’t run out of ink or break easily.
How It Works Like a Snack Bag
Think about a snack bag, like the one you get at school. When you open it, the snacks stay inside until you take some out. A ballpoint pen has a tiny ball inside that rolls as you write. This ball carries the ink from the inside of the pen to the paper, just like how snacks move from your bag to your hand.
Why It Doesn’t Break Easily
If you drop it or squish it, it still works because the ball is protected by a little room inside the pen, kind of like how your snack bag keeps the snacks safe even if you shake it. This makes the pen very durable, meaning it can handle being used and moved around a lot without breaking.
So, a ballpoint pen is like a strong, smart snack bag that helps you write for a long time, no matter what!
