You then spread the cards face up on the table where you can clearly see where the 4 Aces are (as they are the ONLY 4 face down cards).
Then, with just a magical gesture, the 4 Aces appear elsewhere!
Don't worry, your audience is thinking exactly the same as you are at this point -- those 4 Aces are just duplicates... Right!? The thought continues... They must be, as you can still see the 4 cards that are face down in the spread. Those 4 cards are the original Aces... Right?... WRONG!
One by one, you turn them over to reveal they are no longer the Aces -- they have, in fact, been INVISIBLY SWITCHED for 4 other cards.
This is the smoothest, most invisible switch possible!
