Initial Shock by Alex Latorre and Mark Mason (5144)

A spectator selects any card from the deck. They initial the face of their card, on BOTH ends.The rest of the deck is returned to the card box. The selected card is slid into the card box, so it protrudes for about half its length.

No switch of ANY KIND, this REALLY is THEIR INITIALED CARD.

You now write your initials on the card box. In the blink of an eye, your initials jump from the BOX, onto their INITIALED CARD.

You immediately remove the card and hand it to them.

Oh, one more thing… You also hand them the card box. IT’S FULLY EXAMINABLE.
Oh, one more thing… Nothing is PALMED or STOLEN away.
Oh, one more thing…INITIAL SHOCK USES A REGULAR NON GIMMICKED CARD BOX.
Oh, one more thing… It resets in 2 seconds and it is INSTANTLY repeatable with a DIFFERENT card every time.

A REAL MOMENT OF VISUAL MAGIC.
