The Invisible Jokers by Alessandro Criscione
Imagine this...
Show a deck of card having no Jokers... 

The spectator selects any card from the deck, and the card vanishes! 

Now the magician says that he has two special Jokers... The Invisible Jokers! 

He states that he will place them inside the deck face up... 

When he snaps his fingers, the Jokers turn visible, face up in the deck. And between them is the selected card!
