Did you know? This running little man isn't actually moving!
This is called Persistence of Vision: when our eyes see an image, the light signal remains on the retina for about 0.1 seconds. If multiple images switch quickly, the brain integrates them into a "continuous motion", creating the illusion of the little man running.
Why can't you see it sometimes?
- Insufficient light, unclear image transitions;
- Incorrect viewing angle, indistinct afterimage effect;
- Unsuitable eye movement speed, missing the best viewing opportunity.
How to see it more clearly?
- View under strong light or near a light source;
- Take photos or videos with your phone and slow down the playback speed;
- Keep your eyes slightly moving to feel the "instant magic" of the little man running.
This is a small model that makes science fun. Are you ready to experience it yourself?
