Wow them with Shadow Cards from our Card Tricks category!
By way of demonstration the deck is split in half, one packet goes to a fellow, the other to a lady. The fellow glimpses a card in his half and removes it. He is asked to concentrate intently on his chosen card. The lady also glimpses a card in her half, but when she goes to remove it it’s not there. It never was! The card that the lady thought she saw is none other than the card being held by the fellow! Did she see another card altogether? Did the fellow’s intense thought cloud her mind? Only the Shadow knows!
