Magic Finger Optical Illusion

This simple optical illusion is a great distraction, and all you need is fingers and a blank wall.

1. Have the kids look at a blank wall. It should be at least six feet away.
   
   
2. Then they should hold their arms out in front of them and bend their wrists, so their two index fingers are pointing at each other. Tell them to keep focused on the wall and bring their fingers together.
   
   
3. A floating finger should appear between their two index fingers!
