Two Card Transpo (Peter Duffie)

See:
Double Lift Project, Part II

Script:
Ok, I'll show you something interesting with a deck of cards, but you have to be able to remember two cards.

The first one's the queen of hearts which we'll put on top of the card box like this. And the other one's the really important one, the ace of spades, which we'll put down on the table, and cover with the card box and the queen.

And I want you to keep your eyes on the Ace of Spades at the bottom (as you place the pack on top) because I'm going to give the cards a little riffle like this and the ace comes all the way up to the top. So if that's come all the way to the top, that means that underneath the deck and the box must be the Queen of Hearts.
