The Card behind Window or the Card behind Glass is a great magic trick which turns people into believers once they witness what happens. There is a wild card stuck behind a glass – can be a joker or any other card. This card is in plain sight of all the spectators at all times and there is playing around with it from behind the glass.
After that, a card is chosen by a fully shuffled deck of cards and just by waving the hand over the card behind the window, it changes into the spectators card.
