Another common variation is to carry one of the two outside throws up and down rather than throwing it, which may be called the Dummy pattern, or "fake columns" (siteswap: (4,2)), which may be interpreted as adding a carry to the "lone" hand during the two-in-one. "Juggle two balls in one hand, but instead of throwing and catching the third ball with the other hand, you simply hold it in that hand, moving the ball up and down." The carried ball can then be moved in many different ways to complement the pattern. In a variation called Yo-yo (siteswap: (4,2)), or The String, the ball is carried up and down directly above one of the other balls to give the impression that the balls are connected by an invisible string, like a yo-yo.
