Other tricks, like the always well received "quick change," use bright flashes of light to leave a temporary "silhouette" of the magician in the vision of the audience-part of how human vision works is the temporary preservation of images, so that for between 0.1 and 0.5 seconds after an object moves, an image of it lingers; this is the main principle behind animation.
還有常用來炒熱現場氣氛的「快速換裝秀」，則是透過燈光轉換，讓魔術師的身影在觀眾眼中預留「視覺暫存」的記憶──人類視覺能將看到的影像暫時保存，當原本的物體移除後，之前看到的影像還會暫留在眼前（約 0.1 ~ 0.5 秒），這也就是卡通動畫製作的原理。
