How to swap the cards that are in the hands of different audiences

Show viewers deployed a fan in one hand and four kings, and in the other hand four eights. Over the last king of advance should be based on four sevens. Keep in hand eight so that the lowest point was closed by the forefinger and ring fingers, because of what the audience will think that it is seven. Emphasize all the spectators that you hold in one hand, four kings, and the other 4 sevens, although in fact it is eight. Then add seven fake and put them top of the deck. Then fold kings and put them on seven false. Thus, it turned out that these seven are at the top of the deck, as they were located after the last king. Spectators are all confident that lie on top of kings. Next, carefully remove the top 4 cards at the same time say, "I take the kings" and put them on the table. Ask any of the spectators tightly cover their hand. Do the same with the other four cards that are the real kings. Then ask those viewers who keep the card, if they know that in the cards under their hands, get an affirmative answer and ordered cards swapped. Check out the map and all the spectators make sure that your order is executed.
