A Pinned Card Weirdly Swaps Places With A Card That Was Free.

This presentation shows a close-up account of a confined object changing places with a free object.
The magician secures a blank card onto a safety-pin, and hands it to a spectator for examination.
The spectator is then requested to draw anything on a second card.
The magician then causes the two cards to change places in an instant, leaving the spectator's card impaled on the closed pin.
Once again the cards change places, and both are offered for inspection.
