What Is Persistence of Vision?
Magicians can do all kinds of neat stuff, like pulling rabbits out of hats and making objects mysteriously disappear. Science is even more powerful! For this science fair project, you’re going to see if persistence of vision can help you make a floating image of anything you want appear out of thin air.
So, what is persistence of vision? Here’s a hint: It explains why we perceive fast-moving objects as blurs. If you’ve ever watched an electric fan or the propeller on an airplane move, you’ve seen persistence of vision in action!
