This is one of my favorite routines with fingers.
"Please tell us a color." The freely named color is written on a single business card (or somewhere else). "Interesting... I bet I can influence you now to choose a certain finger for instance." You take a bill from your wallet. (The participant can bet as well.) You show your hand (or you draw a hand on the business card or another one):
"Please point to any finger." The spectator freely points to a finger, and of course, this is the one you wanted her to select.
- It is that direct: They announce their choice, and you conclude. There is no 'process', no force, no fumbling, etc.
- It works 100% surefire.
- It uses common objects and a minor preparation.
- Your participant will remember he or she was influenced, somehow.
