A packet of the sixteen royal face cards are show three at a time.
One of each are show in each set of three.
A jack, a queen and a king are shown in each packet of three.
After each packet is show the three court cards are placed faced down in three pile while the last packet of court cards are placed as follow.
The king is placed in front of one pile, the queen is placed in front of another and the jack is placed in front of the last packet.
A little magic and the strangest thing takes place. How the cards end up together is bizarre.
A fun routine, very good one to learn as an exercise to develop some basic handling a little more.
