Fill the glass jar with water and cover it with a card. As you turn the whole thing upside down, the audience can hardly contain themselves. The room quiets down as you precariously position the inverted jar and card a few feet above someone’s head. Just as they thought, no water spills out because the card magically sticks to the mouth of the upside down jar. But wait. . . there’s more.
