Magician spreads the cards, there are a variety of numbers and marks in a loose order Have the audience remember his/her favorite card, take the chosen one from the cards. The pattern on the back of the cards is all in blue. However, when the magician takes a glance at the back of the chosen card, it turns red!

More to happen... When the magician snaps his fingers, all the cards except the chosen one turn white! It is a big hit overseas!
