In-visible by Albert Ho

You deal the cards, they stop at ANY card & remember it. You'll fail to find their card. You introduce the "Invisible Deck", they take their "invisible" card & place it in the visible deck. They say some magic words & Snap! Their invisible card is now visible.
They DON'T tell you what their card is AT ALL.
You can do this any time, anywhere, any deck.
Totally impromptu.
No setup.
No special deck.
No stooges.
No pinky breaking, passes.
No difficult sleights of hand.
No jokes.
You can also do this when you want to give someone a mental or psychological experience.
