I do this force in a similar way that Seige has explained but rather than pull the top packet to the left once it is tilted i drag the bottom packet down and towards myself then tap the top packet on top (in a squaring action though this is purely for show) and then offer the top card of the bottom packet by pushing it forward with my left thumb. I don't even mention anything about the card they have seen the face of. The pushing forward of the card acts like a little mental force in itself "I must have said stop at this one" type of thing.
