Can you imagine what happens when the classic cardtoon meets modern technology?
That's right the aswer is Q!
Q! is your personal assistant and he lives on your cell phone! Adults and kids love him. You already know the impact of such a charming and entertaining character.
Take your deck and spread through the cards, ask your spectator to pick any card and remember it. "Oh no, here it comes the I-guess-your-card-thing"- even before your spectator thinks this, You explain that you have a new partner assisting you today, and he is inside your pocket (intriguing!)
Take your cell phone and show them your little friend Q! He is going to find their card. He removes a card from the pocket, but.... it's the wrong card! The good news is that Q! Is very inteligent, and he has a digital tophat with magical powers. He places the wrong card inside the tophat and it visually changes to the correct card. Let your friend take a round of applause!
Ask if your spectator would like to keep it. Just send it to your spectators cell phone and they'll have remarkable souvenir forever!
