Card magic is a form of illusion that involves tricks and sleight of hand using a standard deck of playing cards. Magicians perform various techniques to create the appearance of impossible feats, such as making cards disappear, change, or appear in unexpected places. The art relies on misdirection, psychology, and practice to amaze audiences. Performers often use a combination of shuffling, dealing, and palming to manipulate cards without the audience noticing. Famous magicians like David Copperfield and Derren Brown have popularized card magic, showcasing its ability to entertain and mystify people of all ages.
