Get prepared for your program, where no one can see, by sorting the cards to setup the very first ten inside deck so that they come in these order: 10, 9, 8, 7, 6, 5, 4, 3, 2, A. The fit (shade and sort) cannot matter. Wear them the deck face down and back in their particular pack. (This would be called "stacking the deck", plus it would-be cheating, if perhaps you were in fact credit cards from the deck as you fixed it, without shuffling them, but this is a trick...)
Attracting through the top ("without" shuffling the deck), place the cards, one-by-one, "face down" on a table so as, beginning on your right and including them toward your remaining, they is: the, 2, 3, 4, 5, 6, 7, 8, 9, 10, using a from the left end, and 10 in the right, but only you understand that.
Show a trusted volunteer from your audience that you would like him/her to go several cards, 1 by 1, from left end of this row off to the right end of row, without scrambling, turning all of them or taking a look at them. Clarify it once more. Switch from your volunteer, so you can't see which or what number of cards are relocated.
Reverse again as soon as your volunteer informs you that s/he has finished this movement.
Look at the very first card on correct end regarding the line without letting any person notice it; this tells you the amount of cards the volunteer moved.
