In your right pocket, place a quarter and a penny.
Reach into right pocket, classic palm the quarter. Pull out penny
(and the quarter). Show penny with right hand displaying between 2nd finger and thumb,
palm up. Quarter can not be seen and hand should look empty except for penny.
Pretend to place the penny in the left hand but actually retain it and let the quarter
drop into the left hand. Close the left hand and move the right had away. You can
reach in a pocket for pen (or magic wand ), ditch the penny. Tap hand with pen open hand
to show quarter.
The sleight used is called a Cap Subtlety by David Roth & Gary Kurtz. They both have
great videos.
