You show a magic window to your friends. It can be skewered by pencils, pen, needles…
You take a playing card, a business card or merely a piece of paper.
You borrow a pencil, a pen or a needle and you pass it through the card against the magic window.
However, when you remove the needle only the card has a hole. The magic window is not damaged.
