interjection

presto

PRES-toh/ˈprestəʊ/

Used to announce a sudden or magical-looking result.

The magician whisks away the cloth, and presto, a rabbit appears!

A text-free two-panel magic reveal: a magician first lifts a cloth to show a bare tabletop, then snaps the cloth away to reveal a white rabbit in the same spot.
Etymology

The image of “standing before” leads to “ready, at hand,” then “quickly.” In a conjurer’s cry, that immediacy suggests something appearing in an instant, as if by magic.
