Jumping Joker Flush

Effect : The performer displays 6 cards – the Ace – King – Queen – Jack and 10 of Spades (a Royal Flush) and a Joker, which he says usually substitutes for any card in the deck.
The Ace is removed from the spread of 5 cards, and placed face down in a small window envelope, through which it is always visible. The Joker is added face up on the Fan of the other 4 cards.
The fan is squared, and the Joker turned Face down. The stack is now mixed, and the performer snaps his fingers,  asking the Joker and Ace to switch places.
When the five cards are now displayed, they are seen to be the complete Flush hand – the A-K-Q-J-and 10 of Spades. When the card from the envelope is removed, it is seen to be the JOKER ! The envelope is seen empty.
We supply all the required cards, the window envelope, and step-by-step illustrated instructions, for this routine, at a very modest price.
Easy to do, the only “move” required is a double lift, and the special props supplied with the routine take care of the rest.
