A double lift is a popular card magic technique used by magicians to lift two cards as if they were one. This creates the illusion that the magician is only handling a single card, allowing for various tricks and effects. The method relies on sleight of hand and misdirection, making it essential for magicians to practice to achieve a smooth execution. In a typical double lift, the magician holds a deck of cards and secretly lifts the top two cards together. By maintaining the appearance of a single card, the magician can perform effects like revealing a chosen card or executing a card switch. Mastering the double lift is crucial for many card tricks in the world of magic.
