This is a really “sweet” effect that keeps them guessing. Magician shows an unprepared brown paper bag. He reaches in and pulls out a RED lollipop. Replacing this, he then pulls out a LIME. The lime lollipop is replaced and a GRAPE one is shown. After replacing the grape, the magician produces a fourth lollipop which is LEMON. He decides to keep this one and hands the bag out to the audience. They are amazed to find the bag completely empty!
