The Persistence of Vision (short story)
Okay, kiddo, I'll try my best to explain it in a way that you can easily understand. Have you ever looked at a sparkler on the Fourth of July or a flashlight in a dark room? What do you see? You see a trail of light left behind, even after the sparkler or the flashlight has moved.
This happens because of something called "persistence of vision." When you look at something, your eyes keep seeing it for a little while after it's gone, kind of like an echo. This is because of the way your eyes and brain work together.
Your eyes work by capturing an image in tiny little pieces, and then sending those pieces to your brain to put together into one picture. But the pieces don't all arrive at the same time. Some pieces come a little bit later than others. But your brain is so good at putting things together that you don't even notice the delay.
So, when you look at something, your eyes keep seeing it for a little while after it's gone because your brain is still putting together the image from all the pieces it received. This is why we see a trail of light after a sparkler or flashlight moves: our eyes are still seeing the light even though it has moved on.
Isn't that cool? Our eyes and brains are amazing things!
