Time travel is the manipulation of time, convincing the audience an event defying explanation occurred in the past or future. Mentalists achieve the time travel effect using psychological techniques, switching devices, or props that allow the performer to alter the sequence of events or predict outcomes as though the mentalist had traversed time.

Time travel is a premise in mentalism performances featuring predictions sealed before the show or revelations suggesting retroactive changes to reality. Time travel methods include sealed predictions, switching gimmicks, trick envelopes, or time-delay mechanisms that create the illusion of temporal manipulation or time distortion.

When mentalists combine storytelling, showmanship, and stagecraft, spectators marvel at the spectacle of time travel effects, experiencing a sense of wonder at the miracle of bending time.
