Effect: Hold your two hands in front of
you at eye level. Point your index fingers
towards each other, as illustrated in the picture
above. Leave a little space (an inch or so)
between your two index fingers. With your fingers
at eye level, stare at and focus on a wall or an
object in the distance (a few feet away).
What You'll See:
You should see a finger with two ends floating in
between your two index fingers. If you are having
problems seeing it, try moving your fingers
toward your eyes (keeping them at eye level). Try
this illusion with your two index fingers
actually touching each other as well.
