A deck of cards is spread face up on the table, showing they are in no particular order. The cards are then dealt into a pile on the table, some being placed face up, some being placed face down. Following a SNAP of the fingers, the deck is spread face up once more, showing that all the cards are now facing the same way. Furthermore, the deck is now in suit and value order Ace to King.
This is also great to show your magician friends, as they will be astonished by this new method!
