Hologram by David Stone

The spectator freely chooses a card that is “marked” on the back with a yellow sticker. You clearly lose the card in the deck and shuffle.

Then you explain that you are going to make the card appear on the top… and thanks to the sticker, everyone will see it !

Indeed, with no suspicious movement, the sticker seems gradually appear on the top of the deck! It even looks like a hologram, as if it was unreal. The only problem is… the sticker appeared in red! Whatever, you just snap the fingers and the sticker turns into yellow ! It changes color instantly and on demand ! And to prove that this is the same card as earlier, you immediately give it for examination !
