Instructions: 1. Stare at the red dot on the girl’s nose for 30 seconds. 2. Turn your eyes to a plain surface (your ceiling or blank wall). 3. Blink repeatedly and quickly.
I could still see a "shadow" of the image when I closed my eyes for well over a minute. It wasn't until I stared at another object for 10 seconds that the image of the girl disappeared when I closed my eyes. I am somewhat surprised that it lasted so long.
Cool!!
